I could not agree more ! 👍🏻 this man is a rockstar of the engine and engineering world ! If you want to do truly great things in life, this is the man you want to be like. His love for this engine and everything to do with it is very clear and I am absolutely fascinated by anything about the Blackbird SR71 and I have been from the first second I knew of it’s existence , I could listen to him talk about it forever! 😄
Hey destin! Agreed. Love to hear from someone who knows what they're talking about; an expert in their respective field. I can tell he has a lot of pride for having worked with this engine, as well he should. The sr71 is just badass, no two ways about it. Plus the engineering that went into it is staggering.
The way he explains everything, with so much love for it, it makes me smile, and it's so much more entertaining, you can see how much he loves talking about it, amazing!
Yes he was great. If it wasn’t for men and women like them there would be no great air aircraft that saved America. Most of America only thinks of the pilots as the heroes. They are only the bus drivers of the sky. If it weren’t for the people who built those planes, and those who keep them ready to fly, there would be no famous pilots. Thank you for those who made the hero’s possible.
@@kandaman304The space shuttle was an engineering failure. Don't get me wrong I love The space shuttle and it's what made me fall in love with space exploration. But NASA was not given enough money and due to political pressure created a dangerous and inefficient space launch platform.
I agree. I'd also like to add the Ducati 996/998 as a worthy addition. The form of the SR71 and Ducati 986/998 both were the result of the engineering input necessary required achieve a specific result. Lockheed & Ducati both did not use one additional item/fastener or material that wasn't necessary to meet the desired outcome.
My uncle was in the Air Force during the Vietnam war and was a hydraulic man on the SR71 while stationed in Okinawa. He's told me some wild stories about the plane. He's still very proud to have been a part of the program.
What is cold war? It is a era that there is no limit for creativity and innovation, NASA used the main frame with 2 whole MB of memory , sent three men to the moon. Now, all we have is Jeff and his blue dildo.
Couldn’t have said it better myself. The 🦨 works program has proven itself time & time again. The SR-71 Blackbird being the cream of the crop for about 40 years +\- until the release of the Stealth. Love it!
The engineering behind this entire plane is incredible, considering just about everything was calculated by hand. This man in a gem. Great story teller.
Not unbelievable, sir. All of us that worked on technology's edge are extremely passionate about or airplanes and weapons systems. I had 17 total years on the F-111 and the amazing things it did was unfortunately overlooked by history and political leaders. Luckily there are some systems that received their accolades such as the Blackbird and rightfully so. There may yet be a plane that will equal its speed and ability but it will never be done in the same way, with gut innovation nor draw that same passion and awe.
@@paulholmes1303 Australia has not forgotten what the F-111 could do. We are now racing to get back the reach that it provided us and that we no longer have.
@@FishandHunt It is a twist of fate that the F-111 was the reason the SR-71 blackbird program was scrapped prematurely just before satellite technology took over quite a period later. "Probably the greatest leap of aircraft technology ever & designed with a slide rule. The fate of these aircraft were sealed in 1968 when, then Secretary of State, Robert McNamara ordered Lockheed to destroy all machinery and tooling associated with making these aircraft (so that no new aircraft could never again be made. It is rumored that McNamara did this to eliminate competition of his 'pet' project, the F-111). Thus no new parts could be made and, after the inventory of whatever parts were available, had to be cannibalized from existing airframes. The aircraft were retired in 1991 over many objections from many officials that the aircraft were still needed."
He is amazing. Many people like him and the passion he has is the reason the project has not been eclipsed today. I have had the pleasure of sitting in the cockpit at the museum of flight in Seattle. Absolutely phenomenal. Could not imagine traveling over 3 times the speed of sound in that. Also, Look up the SR-71 story from Major Brian Shul about "the king of speed".
@@azzajohnson2123 After retiring our F-111's in December of 2010 without a replacement for their long range strike capability and with a growingly aggressive and dangerous threat to our north we are concerned. Almost 12 years after their retirement we still have not got back to the capability that we lost on the day of their retirement. They were nick-named the 'pig' in Australia.
I was a aircraft mechanic for 30 plus years. Men like this were our Michael Jordan's. We were proud to be maintainers of these incredible feats of engineering.
I could listen to him talk about this engine all day! Pitched at a perfect technical level. This guy knows exactly what he's talking about. This engine represents an enormous technical leap.
@@982spyder5 Yes, if you compare the times when it was developed and built. If a plane capable of cruise at twice SR71's speed was developed today (with current technology, chips, CNC, lasers, sensors, etc, etc), it would be great. But, it is almost unbelievable that a plane like SR71 was designed and developed in late 50's with technology of that time. SR71 was a greater feat in its time, than the hipothetical Mach 6 plane would be today.
This is an excellent presentation, very informative, given by Arnie Gunderson, the world’s most knowledgable expert on the J-58, the engines which powered the SR-71. I flew the SR-71 for over 10 years and never had an engine discrepancy; I attribute that good fortune directly to Arnie!
You too must have amazing stories, although from what I understand from Arnie's funny story is that the _sled_ was not an aircraft to play around with: you got it up to designed cruise speed, watched the parameters and route, maybe marvel a bit at the dark sky and curvature of the Earth while sipping your lunch through the orifice in your space suit, and then decelerated back to comprehensible speeds for landing. From his explanation about the bypass air going around the core engine and being injected into the afterburner, I think this is by definition a stato-reactor, is it not? This J-58 would be then a combined turbo-stato-reactor in fact?
@@lxndrlbr Thanks for the observation, and you described the way we flew the SR-71 very well. All of those reactions were accurate. I don't know the technical term: "turbo-stato-reactor," so I couldn't comment on its applicability to the J-58.
@@bcthomas2h90 Sorry for the mistranslation (I am French) I meant a turbojet (compressor + ignition + turbine) in the core J-58 plus a ramjet (compressed air by inlet and aerodynamic pressure + ignition + divergent nozzle) in the nacelle. This design gives me a deeper appreciation for nacelle design!
I worked with Arnie in his years after the J58. We worked together on the 220E program among others. A truly great guy to work with, he even helped me get promoted to take his former position in Business Development. Hope you see this Arnie because I was so happy to see you out there spreading your knowledge and enthusiasm! Take care my friend!
I lived in West Palm Beach while growing up. A neighbor across the street named Bob/Robert, great guy whom I miss talking to, mentioned one day that he had worked at Pratt & Whitney for the Blackbird engine, though I just can’t remember what he said he did for the project. I don’t think I ever knew his last name, or at least can’t remember it now 15 years later. Bob, even in his old age, used to ride his bike around Palm Beach county for 15-20 miles per trip. I used to always see him around random places on his bike then I’d get back home and chat with him for a bit. I wonder if you gents worked with him
@@kodylaird9342 interesting. Lots of interesting steels are amazingly used throughout Jet Engines. I can’t think of any c300 right off hand though. Seen everything from 1 1/4 Cr through m-152. British engine love that. Various 400 series throughout most US engines. Of course, my personal experience is mainly end of life I’m sure the newer generations are more composite and honeycomb materials where they can and especially in the bypass housings
I appreciate the fact that this man volunteers his time to talk about and educate people on this marvel of engineering. It also speaks volumes about how much he enjoyed his work!
This engineer does just a superb job of explaining the complexity of the J58 engine in layman's terms. You can tell he enjoyed his profession. Well done sir!
I have a pretty decent knowledge of piston engines, and a very limited knowledge of turbines. I've read about this engine as a part of a class and seen a lecture on it. Looked up some stuff. Thought it was impressive, but I moved on. There were a few moments in this video where the lightbulb went off because he explained it so well and it really sank in how genius this engine and the plane built around it were. This thing was... 20, maybe 40 years ahead of its time. I've heard that before but this is the first time I'm understanding how and why. It's suchhh a "simple" design, albeit with complex solutions to make that simple overall design work. Incredible.
@@MrBen527Agreed. Even someone like me with next to zero knowledge of jet engines was able to follow and understand his explanations clearly. Truly amazing to explain something very complex in simple terms!
He is one of the lucky ones. You can see the excitement in his eyes that he loved what he was doing. People often forget the most important thing in life when choosing a career path, doing something you love, and finding someone to pay you for it. Incredible story.
It's the worst advice you can give someone if you live in a strong capitalist society. Doing the work you love will never pay you well enough to live comfortably. The hard jobs with responsibility is what pays!
@@Vyker Not true. Reality is ironic. In my career Ive watched the hardest working people get pushed harder and harder with no pay increase in fact the got less pay while the laziest get promoted and increased pay. Myself being the lazy one lol. This guy's story is a dream and absolutely fascinating. Im jealous.
Well said! Same thing I told my boy. Pick a career that is realistic and can earn you a living but more importantly a job you love to do. Otherwise you will be miserable everyday working.
My father worked as a process engineer at Bendix Corporation in South Bend, IN. They helped develop the hydraulic fuel controls for this engine. He was very proud of the contributions he and his coworkers made to this project.
@Peter Angles hi BENDIX, has MANY revisions, @ ETEB, they are in ALTIMETERS, etc,,,you know RONSON LIGHTERS, ,eh ? Well they also made some real serious hydraulic systems for landing gears, that I only knew because I did much A/C WORK for then in the 60 s. & 70s those items were in main office, but in WOODBRIDGE NJ, they ONLY made aerosol can fuels, Stay well, 🇺🇸🇺🇸🇺🇸🇺🇸
@Peter Angles I was just going to say, I had an old Chrysler minivan (93?) that had a Bendix ABS brake system, and they had a recall for it failing. In the back of my mind I always dreaded getting that failure. There was no real repairs for it, if I recall correctly, because it was either prohibitively expensive, or it might fail again. I lucked out myself, but many others around me didn't.
Nice. My biggest contribution to aviation was pitching in $5 for fuel on the Voyager airplane that Dick Rutan flew around the world w/out refueling non-stop.
Those old school engineers were geniuses. Different times, different issues, different vibes. I am so jealous of these old timers, and I wish was born earlier in time. In many ways we do live in shittier times.
Still my favorite airplane of all time. This man is a National Treasure with the information he has and the service he brought to the country. Thank you sir!
This engine, with everything that happened around it, is part of this gentleman's life. You can see it in his eyes and see it in him, it's love. I really liked the "they paid me to work on this !!!" He is part of history himself.
Seriously... my Dad used to build P-51C/D down in Miami when country's would buy them for their Airforce programs in the early 60s, usually island or S. American countries. I thought that was just the coolest job when I was little, building & tuning up those Merlin supercharged beasts in the most beautiful plane of its time & almost all time ! Its crazy how the military would fit them in those moving&storage crates ! I thought that was a great gig... this is Lockheed's SR-71, it flat out, out ran Soviet Era missles, if they actually caught up to her they'd run out of gas... unreal, 70k feet & a space ship that could land, she's just gorgeous if you get to see her up close ! Breathe taking no doubt ! Glad this got posted, it really brought knowledge & memories back. Thanks
This engine is his legacy, it's what he will leave behind. Other than maybe his children, this is what he is most proud of, and he should be proud because it was a monumental achievement. You know you did something right when 45 years later in 2022, the air breathing jet aircraft world speed record that was set by the SR-71 in 1976 is still the world record, it has never been beaten. It also still holds the maximum sustained altitude record. While other aircraft have exceeded the record using "zoom" climbs where the aircraft technically coasts up to an apogee by first accelerating to a high supersonic speed, then trading the kinetic energy of forward motion for altitude.
Being a pilot all my life, I’ve come to realise the real experts are the ones that can explain the most complex scenarios or technicalities in the simplest of ways. And here is one of those rare gems. On a separate note, these guys developed the Mercury, Gemini and Apollo programs back when colour TV was barely available. Look just how good American ambition, industry and science was back then. Be proud of that heritage. It’s pretty astonishing.
It’s is and was. It’s unfortunate we forgot the one thing that allowed us this superiority, integrity. We always aimed to do the right thing. Sometimes we missed, but the objective was universal and the country united. We’ve also entered an era where stupidity is celebrated and rewarded. So minds like this may be few and far between moving forward.
Strongly suspect you're hearing a truly excellent engineer when they utter the phrase "I got to ." They are saying they are grateful to have played a part in creating and perfecting a thing that benefited us all. They are saying they were a member of a team. If they were leading it - as here - it will be mentioned in passing, again as a gift. Nearly every time - as in this case - they'll go on to humbly explain the amazing thing with immense expertise and eloquence. Thank God for truly competent people and their selfless service to mankind.
@@turrafirmaguitarchannel Heh. Many depict all military development as evil until something like Ukraine happens, then are quiet. I lived through and actually fought in the Cold War. This recon airplane may well be one reason big chunks of the world never became a glowing cinder.
People like this gentleman should been seen as celebrity not the guff we have around now. If it was down to me, I'd make sure social media was full of videos like this showing off the best in science, engineering, invention so you could inspire future generations. Thank you for a fantastic presentation.
Right?! I bet this guy doesn't have many Instagram followers despite being a living legend who was part of one of the greatest human accomplishments ever. That's just wrong. Seems we need to revisit our priorities.
Haha I started in Engineering at Clemson, did well in engineering but the calculus and chemistry killed me because I didnt apply myself. Switched to Business Administration lol. Still got good use of my degree though, and enjoyed economics, finance, etc.
Maybe those 2/3 that did not make it should be assigned as whistle blowers. Engineers that make it are not perfect. But they sure get offered wonderful credentials which put them in an ivory tower. Unless you design a world trade center slab support or a Space Shuttle. Oops...
I studied engineering for a year before changing majors into an art degree toward a career in the technical side of entertainment. Part of me worried I would regret it but my career in entertainment has been far more rewarding and fulfilling than I ever dreamed back in those days. It would have been one thing to work on planes like this, but my friend who did become an engineer ended up working on washing machine parts for General Electric and his life has been nowhere near as exciting as mine.
I've worked with Arnie. He was always very passionate about his time at P&W and this program. Nice to see he has found a place to share his stories with everyone.
Not only stories but mainly wisdom! No one can replace these old guys who were used to live for their jobs. Men are no longer willing and allowed (by society and spouses) to have such an approach which was quite normal in the past.
@@maccedorejoice3981 because it's true lol they don't make gentleman like this anymore. Sure there is some brilliant minds up and coming but they aren't the same sort of disposition or have the same sort of passion, or knowledge of historical moments and milestones in history. This guy is like the encyclopaedia of this engine just from his memory and brain. Total gem!
I worked at Excello in Orlando, Florida from 1983-1986. In 1985 one of the plants up north went on strike and all the production equipment was moved to Orlando and set up to make the stage 1 and stage 2 compressor blades for this engine. I was the one chosen to do the set up and production of these blades. The forgings were made from titanium. Every time I go into an air museum and see the engine on the cart, there's a good chance I made some of the blades in this engine.
Meh dad, and I as well worked at excellent. When my dad retired, he got fucked for pensions that providence company bout out budny. Old polish guy the whole plant polish. Great engineering and grinding plus or minus 2 tenths. For civies that's 0.0001 to 0.00002 tolerance. That's insane I worked from 77 to 78 summer job program high school great place man too bad they sold out
Cool to hear this. I worked a brief time as an inspector at a titanium wing spar manufacturer on Long Island. Another example of how socialist unions and thinkers have undermined the nation systemically for decades. Stopping work that provides the very protection for our nation and now forced our best innovators and industrialists to walk away and set up abroad.
Mr Harnish, what alloys did they use to make the high-pressure turbine blades for this unique powerful engine, and what was the turbine entry temperature ?
This is the best talk I have ever heard from anyone on sr71 systems. I never got to meet him. A true HERO here in our view. This man and people in his company are ones who deserve medals. My hat is off to you sir.
I agree Mike. He is amazing. I honestly don't understand very much of what he was saying but I was glued to my phone just listening to him talk. It was impressive for sure.
Colonel Richard Graham (usaf ret) is often down at Frontiers of Flight at Love Field in Dallas/Ft Worth. he was my wing commander at Beale (9th SRW) and he commanded the wing that flew the SR-71, was 1SRS squadron commander that flew the SR-71 and a pilot of the SR-71. if you catch him when he's there, he has hours of knowledge and stories to tell.
I worked as an SR-71 jet engine mechanic from 87 till its retirement and have never seen anyone explain everything so clearly in such a short manner. Would have loved to have met him and learned from him while I was working on the J58. One thing I would tend to disagree with is that he states that working with the lines was easy. Not so much. Everything on that engine is built very durably and wants to fight you, especially when ops wants the plane back in a hurry and everything you touch is hot as hell. Let’s just say a mechanic’s world and an engineer’s world are two very different places. Great experience listening to him! I learned a lot.
It’s that way on cars too Like what jackass designed a car that you have to take the wheel and shock on one side to change the alternator or change the damn headlight It’s one reason . They don’t have to work on it
XRP When exactly would the information that Arnie is generously sharing with us be declassified. How does that work. Are the inner workings of this plane automatically declassified the same day the program was discontinued? Thank you for your time.
As a gear head, it warms my heart to know that some old school drag racers working at Pratt & Whitney had to brainstorm how to jump-start this monster.
I'm a gear head myself... a oldsmobile man ....was sad to hear about all the buick 400's and 430's I've also heard that 400 and 425 oldsmobiles were used as well for starter engines but I fully agree with the old man as he lived through this awesome time
The expansion factor was so great, fuel would leak all through the frame from the fuel cell at high speed. The J58 is by far the best engineering success design for super sonic travel. Amazing commentary.
This video is a treasure. I have read the book on the Skunkworks, and this perspective from the engine manufacturer’s engineer helps round out more of the story surrounding that program. I never thought about the challenges they had to overcome such as the extreme (cooling!) heat surrounding the engine, controls pre-dating computers, inventing alloys that I’ve just heard for the first time here, and 6” of longitudinal thermal expansion! We joke about “unobtainium” a lot, but this is what lots of government money and high priority can achieve. What an engineering accomplishment!
As a life long machinist I have worked with some of exotic materials mentioned in the video. Titanium cuts like stainless and is a joy to work with. Just don't start a delta fire in your chip bin. The cooling systems are reminiscent to rocket motors where they use the fuel to cool the nozzle and other parts from melting. I've seen the actual SpaceX drawing for the raptor engine fuel pump rotor and it is wild. I am so amazed by what people did back then with only slide rules and creativity.
This man gives an absolute masterclass in how to explain complicated engineering concepts in the most simplest way - and he does it with a smile. My 8 year old boy and girl is going to hear this guy when I play it for them and they're going to take their first step into the mechanical world!
I agree. Having studied engineering myself I can appreciate professors who could teach this stuff in such a way to actually make sense. More sense than reading a textbook full of graphs, theory and equations.
Thats what i want to go to school for. Im just concerned because im already 24yo and i didnt try in high school so my gpa is trash. Im in tech school rn for Mechanical Engineering Technology which is basically drafting and cnc programming with a little extra thrown in. Its free so figured id at least get that done. Im also a machinist so its a very nice addition to my current career. But still my goal is a bachelors in mechanical engineering. Hope i can make it and afford it.
So funny that he asked if there were any questions, and as an afterthought, told the most amazing stories ever. I could listen to this guys stories by the hour.
Video records like this are historical treasures that will be preserved forever for all subsequent generations to glean a bit of what it was like in earlier times. Thanks to all who take the the time to preserve this piece of history.
When I got hired at Pratt, there’s a sign hanging in the hallway of the engineering building that reads something like “through these halls walked some of the world’s best propulsion systems engineers”. I am paraphrasing, can’t recall the exact words, but It was such an emotional motivational sign to walk pass everyday going to my desk. I had mentors like this gentleman throughout my Pratt career and it made things a lot more exciting, just the love for the product
I remember that banner in the engineering building. Saddens me to see Willgoose turbine labs gone. & GOD do I miss watching the 727's leave from the runway when was working over in the Klondike.
What they accomplished is truly amazing. “ HOW DO YOU EAT AN ELEPHANT? ONE BITE AT A TIME ! So many details to work out to make the engine run so efficiently. And they were loving it .
I could listen to his stories all day. So much passion and enthusiasm. And amazing storytelling. And this is only a single aspect of the program. Just wow.
I don't know how this ended up in my feed, but I really enjoyed this man's passion about the project. His explanations were fantastic - engineering, but without being overwhelming. Great video.
Wow. How cool is it to have an enthusiastic and passionate person describing such an iconic engine, but they were also an engineer on the team that built it? This looks like the textbook example of doing what you love for a living. This did not feel like a 24 min video! Keep bringing content like this!
This man obviously loves talking about this engine and he makes it easy for a layperson to understand. I'm also struck by how much that engine looks like an H.R. Giger sculpture. What a wonderful video.
I have watched countless videos on the SR-71. This would have to be in the top 3 informative and entertaining videos on the SR-71. I could listen to Mr Gunderson for hours. Thanks for posting this video.
@@feelinghealingfrequences7179 Here is one: ua-cam.com/video/6nuAZfKSvvg/v-deo.html Lots of technical tidbits, e.g. 90,000 feet. Not 80. Cruise at one mile every two seconds. With throttles advanced: One mile in 1.5 seconds. 3,520fps. = 2,400mph. When evading missiles: It will go a lot faster than the book says it will go. Sled Driver by Brian Shul is worth every penny.
That man makes me proud to be American. A true engineer …. After an illustrious career, he is still excited and enthusiastic about this amazing technology.
Arnie, in addition to being a legendary engineer, you're an exceptional storyteller. Thank you for packing so much interesting information into a short clip about this amazing engine. You and your engineering generation were brilliant when America needed it most.
This Gentleman is Incredible explaining everything. I never knew any of this and I've worked on aircraft engines, most notably the metal's involved and there complexity. Thank you sir for you knowledge and your service to America.
I am honored to hear this gentleman share what he can about his "job" working on water heaters. I sat and smiled the whole time beholding his joy and pride in his job, his country and his engine.
I was the last Tech. Lead on the fuel control systems on this engine. It was the highlight of my career more than 30 years ago. The people at P&W were the absolute best people I've ever worked with. Stan Dees was the head of the program in those days.
question mr engineear, why wouldn't a mirror close to the atmosphere, work? image they somehow get a big mirror very high up, a hot air balloon or something and then they could use a telescope [nasa grade telescope] to look at the reflection and spy on the soviets this way? could be a concaved mirror at a perfect mathematical angle. i know a satellite would be best, but if they are using planes this isnt too crazy
I would love to buy him lunch and listen to all his wonderful stories. He truly is a great engineer and loves what he was able to add to the program. His passion is contagious!
I am not an engineer but I love planes. I could listen to this guy all day. Not just because the subject matter but because you can see his enthusiasm, passion, and pride when he explains things. He makes it easier to understand.
Incredible! As an engineer myself, the talent and skills of these guys are only something I could dream about. Such passion and knowledge to share. Just fantastic.
I'm an engineer in the power industry and for the last 20 years, I've done startups on numerous gas turbine power plants. I can't get enough of it!! Awesome video!!
Thank you. An excellent talk. It is easy to tell that you loved your job and are very proud of the group's performance. I am a 71 year old USAF man, and I am proud of all of you that worked hard and excelled in your mission. Blessings.
This has got to be one of the most interesting things I've watched in a long long time. I never had the chance to go to school or work around such things, but yet I have a very good understanding of most of what he talks about here. The biggest thing that strikes me about the whole project that he points out, is that so many mundane things that I have had some experience with in my (common) life through physics, toolmaking, and engine building had created such an incredible and fascinating piece of machinery. I could converse with him for days!
What’s sad is that there is so much institutional knowledge that will be lost when these guys are gone; so much respect for the engineers. We tend to focus on the drivers and forget the many, many others that built it and made it work
One take, just like that. So cool to hear engineering stories after reading so many pilot stories from the blackbird program. Curious about engine technology today.
Forget influencers kids. These are the real heroes you need to emulate right here
Influemediocrity kids? Or influemoron kids? or influeadhd kids? or influecluess kids? or influedumb kids? or influeuseless kids? Yep!
Absolutely. Degenerate heroes for the kids these days courtesy of big tech.
This is in my saved videos… keeps coming around anyway !

The sr71 is just badass, no two ways about it. Plus the engineering that went into it is staggering.
what material they use for these jet engines because if so much power is put into them will it not burn???
SR71 program may be the coolest thing any airforce has ever done. I certainly can't think of anything more lunatic and fascinating
A man like this is a national treasure. His knowledge and experience is priceless.
These are the men behind American excellence in technology and innovation. Unfortunately, it's not cool to be a man anymore lol
why did two people say the words national treasure for some reason
It really is prizeless.
Literally the price of going to engineering school.
The original Scotty..."I'm givin' her all she's got!"
The way he explains everything, with so much love for it, it makes me smile, and it's so much more entertaining, you can see how much he loves talking about it, amazing!
I agree!
How can he not be passionate about it? He said spent 20 years of his life on it. But I agree it’s nice seeing people energetic about things like this.
Love your work and it isn't work
Yes he was great. If it wasn’t for men and women like them there would be no great air aircraft that saved America. Most of America only thinks of the pilots as the heroes. They are only the bus drivers of the sky. If it weren’t for the people who built those planes, and those who keep them ready to fly, there would be no famous pilots. Thank you for those who made the hero’s possible.
You took the mouth right out of my words. Beautiful job!
This man's value is 1000x of any "influencer" or politician.
Politicians don't create anything. Most of those parasites just destroy.
He should run for office. He smarter than 99% of people in the government. When they ask for info they come to people like him.
In my opinion, the SR-71 is the finest work of engineering blended with art ever created. This story is 100% amazing.
I would put that second to the Space Shuttle though.
@@kandaman304The space shuttle was an engineering failure. Don't get me wrong I love The space shuttle and it's what made me fall in love with space exploration. But NASA was not given enough money and due to political pressure created a dangerous and inefficient space launch platform.

I agree. I'd also like to add the Ducati 996/998 as a worthy addition. The form of the SR71 and Ducati 986/998 both were the result of the engineering input necessary required achieve a specific result.
Lockheed & Ducati both did not use one additional item/fastener or material that wasn't necessary to meet the desired outcome.
Just pure science, the "artwork" is subjective and the science is objective. 😅

What is cold war? It is a era that there is no limit for creativity and innovation, NASA used the main frame with 2 whole MB of memory , sent three men to the moon.
Now, all we have is Jeff and his blue dildo.
The engine and plane were great. The time? Eeeh, not so much.
Remember, we were close to nuclear holcaust every other Saturday...
Couldn’t have said it better myself. The 🦨 works program has proven itself time & time again. The SR-71 Blackbird being the cream of the crop for about 40 years +\- until the release of the Stealth. Love it!
Without having read your comment, I also commented: "What a legacy; what stories. What an aircraft." Superlatives all around.
The engineering behind this entire plane is incredible, considering just about everything was calculated by hand. This man in a gem. Great story teller.

@@himanshusingh5214 what are you talking about, bro?
Me, fiddling with my 3D printer: "You know, I'm something of an engineer myself." 😏
This guy is a national treasure. Unbelievable how passionate he is about this project.
Not unbelievable, sir. All of us that worked on technology's edge are extremely passionate about or airplanes and weapons systems. I had 17 total years on the F-111 and the amazing things it did was unfortunately overlooked by history and political leaders. Luckily there are some systems that received their accolades such as the Blackbird and rightfully so. There may yet be a plane that will equal its speed and ability but it will never be done in the same way, with gut innovation nor draw that same passion and awe.
@@paulholmes1303 Australia has not forgotten what the F-111 could do. We are now racing to get back the reach that it provided us and that we no longer have.
@@FishandHunt It is a twist of fate that the F-111 was the reason the SR-71 blackbird program was scrapped prematurely just before satellite technology took over quite a period later. "Probably the greatest leap of aircraft technology ever & designed with a slide rule. The fate of these aircraft were sealed in 1968 when, then Secretary of State, Robert McNamara ordered Lockheed to destroy all machinery and tooling associated with making these aircraft (so that no new aircraft could never again be made. It is rumored that McNamara did this to eliminate competition of his 'pet' project, the F-111). Thus no new parts could be made and, after the inventory of whatever parts were available, had to be cannibalized from existing airframes. The aircraft were retired in 1991 over many objections from many officials that the aircraft were still needed."
He is amazing. Many people like him and the passion he has is the reason the project has not been eclipsed today. I have had the pleasure of sitting in the cockpit at the museum of flight in Seattle. Absolutely phenomenal. Could not imagine traveling over 3 times the speed of sound in that. Also, Look up the SR-71 story from Major Brian Shul about "the king of speed".
@@azzajohnson2123 After retiring our F-111's in December of 2010 without a replacement for their long range strike capability and with a growingly aggressive and dangerous threat to our north we are concerned. Almost 12 years after their retirement we still have not got back to the capability that we lost on the day of their retirement. They were nick-named the 'pig' in Australia.
I was a aircraft mechanic for 30 plus years. Men like this were our Michael Jordan's. We were proud to be maintainers of these incredible feats of engineering.
I could listen to him talk about this engine all day!
Pitched at a perfect technical level.
This guy knows exactly what he's talking about.
This engine represents an enormous technical leap.
Is this the zenith of American aerospace technology?
@@982spyder5 Yes, if you compare the times when it was developed and built. If a plane capable of cruise at twice SR71's speed was developed today (with current technology, chips, CNC, lasers, sensors, etc, etc), it would be great.
But, it is almost unbelievable that a plane like SR71 was designed and developed in late 50's with technology of that time.
SR71 was a greater feat in its time, than the hipothetical Mach 6 plane would be today.
He would have made a great teacher...

Its a shame this level of engineering and efficiency hasnt been applied to other areas of technology in our lives.(automotive/trains/power generation)
This is an excellent presentation, very informative, given by Arnie Gunderson, the world’s most knowledgable expert on the J-58, the engines which powered the SR-71. I flew the SR-71 for over 10 years and never had an engine discrepancy; I attribute that good fortune directly to Arnie!
You too must have amazing stories, although from what I understand from Arnie's funny story is that the _sled_ was not an aircraft to play around with: you got it up to designed cruise speed, watched the parameters and route, maybe marvel a bit at the dark sky and curvature of the Earth while sipping your lunch through the orifice in your space suit, and then decelerated back to comprehensible speeds for landing.
From his explanation about the bypass air going around the core engine and being injected into the afterburner, I think this is by definition a stato-reactor, is it not? This J-58 would be then a combined turbo-stato-reactor in fact?
@@lxndrlbr Thanks for the observation, and you described the way we flew the SR-71 very well. All of those reactions were accurate. I don't know the technical term: "turbo-stato-reactor," so I couldn't comment on its applicability to the J-58.
@@bcthomas2h90 Sorry for the mistranslation (I am French) I meant a turbojet (compressor + ignition + turbine) in the core J-58 plus a ramjet (compressed air by inlet and aerodynamic pressure + ignition + divergent nozzle) in the nacelle.
This design gives me a deeper appreciation for nacelle design!
@@lxndrlbr Yes, I would say that is a good thumbnail description of the process.
Please divulge the actual top speed.
I worked with Arnie in his years after the J58. We worked together on the 220E program among others. A truly great guy to work with, he even helped me get promoted to take his former position in Business Development. Hope you see this Arnie because I was so happy to see you out there spreading your knowledge and enthusiasm! Take care my friend!
Thanks for your service! What an amazing project
I lived in West Palm Beach while growing up. A neighbor across the street named Bob/Robert, great guy whom I miss talking to, mentioned one day that he had worked at Pratt & Whitney for the Blackbird engine, though I just can’t remember what he said he did for the project. I don’t think I ever knew his last name, or at least can’t remember it now 15 years later. Bob, even in his old age, used to ride his bike around Palm Beach county for 15-20 miles per trip. I used to always see him around random places on his bike then I’d get back home and chat with him for a bit. I wonder if you gents worked with him
@@-Ncrypt Sorry, I never worked the J58 program myself so did not know him
Was c300 maraging steel around then? Seems like it woulda been a perfect candidate for something like this engine
@@kodylaird9342 interesting. Lots of interesting steels are amazingly used throughout Jet Engines. I can’t think of any c300 right off hand though. Seen everything from 1 1/4 Cr through m-152. British engine love that. Various 400 series throughout most US engines. Of course, my personal experience is mainly end of life I’m sure the newer generations are more composite and honeycomb materials where they can and especially in the bypass housings
My grandfather used to run a machine at Pratt and Whitney!!! I miss him dearly. He passed many years ago! I'm not a cnc machinist!
I appreciate the fact that this man volunteers his time to talk about and educate people on this marvel of engineering. It also speaks volumes about how much he enjoyed his work!
Yep when retired you’ll do that I’m sure closely gardened secrets in there to
Does anyone know this mans name? He is my hero, I would have loved to be involved with him and his crew back then...!
I love how he asked for questions early on, but said, screw it, I have more stories... This man is a national treasure.
This engineer does just a superb job of explaining the complexity of the J58 engine in layman's terms. You can tell he enjoyed his profession. Well done sir!
I have a pretty decent knowledge of piston engines, and a very limited knowledge of turbines. I've read about this engine as a part of a class and seen a lecture on it. Looked up some stuff. Thought it was impressive, but I moved on.
There were a few moments in this video where the lightbulb went off because he explained it so well and it really sank in how genius this engine and the plane built around it were. This thing was... 20, maybe 40 years ahead of its time. I've heard that before but this is the first time I'm understanding how and why. It's suchhh a "simple" design, albeit with complex solutions to make that simple overall design work. Incredible.
Best explanation so far!!!
@@MrBen527Agreed. Even someone like me with next to zero knowledge of jet engines was able to follow and understand his explanations clearly. Truly amazing to explain something very complex in simple terms!
He's not just an engineer, he's a legend
He is one of the lucky ones. You can see the excitement in his eyes that he loved what he was doing.
People often forget the most important thing in life when choosing a career path, doing something you love, and finding someone to pay you for it. Incredible story.
It's the worst advice you can give someone if you live in a strong capitalist society. Doing the work you love will never pay you well enough to live comfortably. The hard jobs with responsibility is what pays!
@@Vyker Not true. Reality is ironic. In my career Ive watched the hardest working people get pushed harder and harder with no pay increase in fact the got less pay while the laziest get promoted and increased pay. Myself being the lazy one lol. This guy's story is a dream and absolutely fascinating. Im jealous.
@@jasonmillner6416 When I was young I was poor but after a lifetime of hard work I am no longer young.
@@randyhanson837 Amen.
Well said! Same thing I told my boy. Pick a career that is realistic and can earn you a living but more importantly a job you love to do. Otherwise you will be miserable everyday working.
This MAN is a legend !!
My father worked as a process engineer at Bendix Corporation in South Bend, IN. They helped develop the hydraulic fuel controls for this engine. He was very proud of the contributions he and his coworkers made to this project.
I'm sure he was, and rightly so.
@Peter Angles hi BENDIX, has MANY revisions, @ ETEB, they are in ALTIMETERS, etc,,,you know RONSON LIGHTERS, ,eh ? Well they also made some real serious hydraulic systems for landing gears, that I only knew because I did much A/C WORK for then in the 60 s. & 70s those items were in main office, but in WOODBRIDGE NJ, they ONLY made aerosol can fuels, Stay well,
🇺🇸🇺🇸🇺🇸🇺🇸
@Peter Angles That too! Bendix Aviation was a big part of the operation in South Bend too. They made aircraft brakes and struts, fuel controls, etc.
@Peter Angles I was just going to say, I had an old Chrysler minivan (93?) that had a Bendix ABS brake system, and they had a recall for it failing. In the back of my mind I always dreaded getting that failure. There was no real repairs for it, if I recall correctly, because it was either prohibitively expensive, or it might fail again. I lucked out myself, but many others around me didn't.
Nice. My biggest contribution to aviation was pitching in $5 for fuel on the Voyager airplane that Dick Rutan flew around the world w/out refueling non-stop.
I have heard alot of stories from pilots but never from the engineers. This was really awsome. These guys were as big of a hero as any of the pilots.
Pilot stories are boring, all of them bragging abouy accelerating away from interceptors or missiles.
Engineers and mechanica have the real stories.
@@DanSlotea I agree on that. But that makes me sound selfish, since am an engineer too.
I could listen to this man for hours on end. He's passion and knowledge for and about the plain is just astounding
You should hear what he has to say about the savannah!
@@triumphdollysprint wonder what his thoughts are on valleys and plateaus.
Come to Palmdale one day to the Joe Davies Airpark at Plant 42. There's an A12 and SR71 with a J58 on display.
It's the mountains where his knowledge peaks.
@@EasyMoneySG he gets pretty deep talking about valleys. Always seems pretty flat when discussing plateaus, but his knowledge is still expansive!
Those old school engineers were geniuses. Different times, different issues, different vibes. I am so jealous of these old timers, and I wish was born earlier in time. In many ways we do live in shittier times.
Their successors seemed to have gone to SpaceX.
Still my favorite airplane of all time. This man is a National Treasure with the information he has and the service he brought to the country. Thank you sir!
How are you doing, can I have your contact so that we can talk more?
@@maccedorejoice3981 looks like you’ve been making the same comments to others as well as me!
Fake account?
@@dibaz1 nope my account is not fake ,I just need a friend here , trust me
Exactly my thoughts, Kevin.
This engine, with everything that happened around it, is part of this gentleman's life. You can see it in his eyes and see it in him, it's love. I really liked the "they paid me to work on this !!!" He is part of history himself.
Seriously... my Dad used to build P-51C/D down in Miami when country's would buy them for their Airforce programs in the early 60s, usually island or S. American countries. I thought that was just the coolest job when I was little, building & tuning up those Merlin supercharged beasts in the most beautiful plane of its time & almost all time ! Its crazy how the military would fit them in those moving&storage crates ! I thought that was a great gig... this is Lockheed's SR-71, it flat out, out ran Soviet Era missles, if they actually caught up to her they'd run out of gas... unreal, 70k feet & a space ship that could land, she's just gorgeous if you get to see her up close ! Breathe taking no doubt ! Glad this got posted, it really brought knowledge & memories back. Thanks
This engine is his legacy, it's what he will leave behind. Other than maybe his children, this is what he is most proud of, and he should be proud because it was a monumental achievement. You know you did something right when 45 years later in 2022, the air breathing jet aircraft world speed record that was set by the SR-71 in 1976 is still the world record, it has never been beaten. It also still holds the maximum sustained altitude record. While other aircraft have exceeded the record using "zoom" climbs where the aircraft technically coasts up to an apogee by first accelerating to a high supersonic speed, then trading the kinetic energy of forward motion for altitude.
@@racerex340 I don't think many parents could rattle off that many facts and keep it interesting talking about their kids.
That engine and the whole A12/SR71 programs are the 8th wonder of the world.
Being a pilot all my life, I’ve come to realise the real experts are the ones that can explain the most complex scenarios or technicalities in the simplest of ways. And here is one of those rare gems.
On a separate note, these guys developed the Mercury, Gemini and Apollo programs back when colour TV was barely available. Look just how good American ambition, industry and science was back then. Be proud of that heritage. It’s pretty astonishing.
It’s is and was. It’s unfortunate we forgot the one thing that allowed us this superiority, integrity. We always aimed to do the right thing. Sometimes we missed, but the objective was universal and the country united. We’ve also entered an era where stupidity is celebrated and rewarded. So minds like this may be few and far between moving forward.
Strongly suspect you're hearing a truly excellent engineer when they utter the phrase "I got to ." They are saying they are grateful to have played a part in creating and perfecting a thing that benefited us all. They are saying they were a member of a team. If they were leading it - as here - it will be mentioned in passing, again as a gift. Nearly every time - as in this case - they'll go on to humbly explain the amazing thing with immense expertise and eloquence. Thank God for truly competent people and their selfless service to mankind.
Truth.
You are right to a point. This was a military machine, debatable how much benefit humanity has derived from this exercise.
@@turrafirmaguitarchannel Heh. Many depict all military development as evil until something like Ukraine happens, then are quiet. I lived through and actually fought in the Cold War. This recon airplane may well be one reason big chunks of the world never became a glowing cinder.
@@generessler6282 Thank you, Gene. :thumbsup
Not a snowflake in sight
People like this gentleman should been seen as celebrity not the guff we have around now.
If it was down to me, I'd make sure social media was full of videos like this showing off the best in science, engineering, invention so you could inspire future generations.
Thank you for a fantastic presentation.
Right?! I bet this guy doesn't have many Instagram followers despite being a living legend who was part of one of the greatest human accomplishments ever. That's just wrong. Seems we need to revisit our priorities.
Well said.
Around 2/3 of engineering students will either drop out or change majors. Engineering is hard, but damn is it amazing. This guy is absolutely awesome.
90%droput rate here
Haha I started in Engineering at Clemson, did well in engineering but the calculus and chemistry killed me because I didnt apply myself. Switched to Business Administration lol. Still got good use of my degree though, and enjoyed economics, finance, etc.
My Dad was an aeronautical engineer. I got none of his math ability.
Maybe those 2/3 that did not make it should be assigned as whistle blowers. Engineers that make it are not perfect. But they sure get offered wonderful credentials which put them in an ivory tower. Unless you design a world trade center slab support or a Space Shuttle. Oops...
I studied engineering for a year before changing majors into an art degree toward a career in the technical side of entertainment. Part of me worried I would regret it but my career in entertainment has been far more rewarding and fulfilling than I ever dreamed back in those days. It would have been one thing to work on planes like this, but my friend who did become an engineer ended up working on washing machine parts for General Electric and his life has been nowhere near as exciting as mine.
Man I could listen to this guys stories for hours. He was extremely lucky to work on one of the coolest aircraft ever made

It makes me sad that when his generation is gone, we will lose a LOT of really interesting stories.
Why saying that?
Not only stories but mainly wisdom! No one can replace these old guys who were used to live for their jobs. Men are no longer willing and allowed (by society and spouses) to have such an approach which was quite normal in the past.
@@maccedorejoice3981 because it's true lol they don't make gentleman like this anymore. Sure there is some brilliant minds up and coming but they aren't the same sort of disposition or have the same sort of passion, or knowledge of historical moments and milestones in history. This guy is like the encyclopaedia of this engine just from his memory and brain. Total gem!
@@Jarek_73 your right
You should aspire to be the type of person you describe
I worked at Excello in Orlando, Florida from 1983-1986. In 1985 one of the plants up north went on strike and all the production equipment was moved to Orlando and set up to make the stage 1 and stage 2 compressor blades for this engine. I was the one chosen to do the set up and production of these blades. The forgings were made from titanium. Every time I go into an air museum and see the engine on the cart, there's a good chance I made some of the blades in this engine.
Meh dad, and I as well worked at excellent.
When my dad retired, he got fucked for pensions that providence company bout out budny.
Old polish guy the whole plant polish. Great engineering and grinding plus or minus 2 tenths.
For civies that's 0.0001 to 0.00002 tolerance.
That's insane
I worked from 77 to 78 summer job program high school great place man too bad they sold out
Cool to hear this. I worked a brief time as an inspector at a titanium wing spar manufacturer on Long Island.
Another example of how socialist unions and thinkers have undermined the nation systemically for decades. Stopping work that provides the very protection for our nation and now forced our best innovators and industrialists to walk away and set up abroad.
@@geokeyey1116 Dude, *NO ONE* cares! I’m serious.
Mr Harnish, what alloys did they use to make the high-pressure turbine blades for this unique powerful engine, and what was the turbine entry temperature ?
60 years later and the SR-71 still looks out of this world.
What a beauty!!!
This is the best talk I have ever heard from anyone on sr71 systems. I never got to meet him. A true HERO here in our view. This man and people in his company are ones who deserve medals. My hat is off to you sir.
I agree Mike. He is amazing. I honestly don't understand very much of what he was saying but I was glued to my phone just listening to him talk. It was impressive for sure.
Colonel Richard Graham (usaf ret) is often down at Frontiers of Flight at Love Field in Dallas/Ft Worth. he was my wing commander at Beale (9th SRW) and he commanded the wing that flew the SR-71, was 1SRS squadron commander that flew the SR-71 and a pilot of the SR-71. if you catch him when he's there, he has hours of knowledge and stories to tell.
I worked as an SR-71 jet engine mechanic from 87 till its retirement and have never seen anyone explain everything so clearly in such a short manner. Would have loved to have met him and learned from him while I was working on the J58.
One thing I would tend to disagree with is that he states that working with the lines was easy. Not so much. Everything on that engine is built very durably and wants to fight you, especially when ops wants the plane back in a hurry and everything you touch is hot as hell. Let’s just say a mechanic’s world and an engineer’s world are two very different places. Great experience listening to him! I learned a lot.
It’s that way on cars too
Like what jackass designed a car that you have to take the wheel and shock on one side to change the alternator or change the damn headlight
It’s one reason . They don’t have to work on it
Great perspective. Thanks for your service
Nice insights.
XRP When exactly would the information that Arnie is generously sharing with us be declassified. How does that work. Are the inner workings of this plane automatically declassified the same day the program was discontinued? Thank you for your time.
Welcome to aviation (joke). After working on GA I have come up with a saying, "the only thing easy about a plane is to crash it".
As a gear head, it warms my heart to know that some old school drag racers working at Pratt & Whitney had to brainstorm how to jump-start this monster.
Yeah but no more galaxy engines. No-one in this gang never flew a Chinook with the pony start turbine? It will split your ear drum but it works.
I've heard that oldsmobile 425 rocket V8's were used to jump start them but I can not confirm this information something I read over the years
I'm a gear head myself... a oldsmobile man ....was sad to hear about all the buick 400's and 430's I've also heard that 400 and 425 oldsmobiles were used as well for starter engines but I fully agree with the old man as he lived through this awesome time
The expansion factor was so great, fuel would leak all through the frame from the fuel cell at high speed. The J58 is by far the best engineering success design for super sonic travel. Amazing commentary.
This video is a treasure. I have read the book on the Skunkworks, and this perspective from the engine manufacturer’s engineer helps round out more of the story surrounding that program. I never thought about the challenges they had to overcome such as the extreme (cooling!) heat surrounding the engine, controls pre-dating computers, inventing alloys that I’ve just heard for the first time here, and 6” of longitudinal thermal expansion! We joke about “unobtainium” a lot, but this is what lots of government money and high priority can achieve. What an engineering accomplishment!
As a life long machinist I have worked with some of exotic materials mentioned in the video. Titanium cuts like stainless and is a joy to work with. Just don't start a delta fire in your chip bin. The cooling systems are reminiscent to rocket motors where they use the fuel to cool the nozzle and other parts from melting. I've seen the actual SpaceX drawing for the raptor engine fuel pump rotor and it is wild. I am so amazed by what people did back then with only slide rules and creativity.
Absolutely amazed about the expansion of this behemoth. Thanks to everyone at the AirZoo. (AZO)
You can tell that he's really proud of the work he did on this engine. I am absolutely blown away by the engineering of this engine.

True
When I got hired at Pratt, there’s a sign hanging in the hallway of the engineering building that reads something like “through these halls walked some of the world’s best propulsion systems engineers”. I am paraphrasing, can’t recall the exact words, but It was such an emotional motivational sign to walk pass everyday going to my desk.
I had mentors like this gentleman throughout my Pratt career and it made things a lot more exciting, just the love for the product
I remember that banner in the engineering building. Saddens me to see Willgoose turbine labs gone. & GOD do I miss watching the 727's leave from the runway when was working over in the Klondike.
Well considering this guy said 40x15 is 6000 some psi.. i would take that sign down

Probably the most informative narration I’ve ever heard on the SR 71 engines. Thank you sir thank you for working on those to make it happen.
The SR71 is an engineering marvel, and is one of the most awesome aeroplanes ever built.
And Still Is
Amazing what people can do when it comes to killing others. This only exists for military use.
As much as I love the SR71, the XB70 still takes the cake...

Don’t be toxic bro
This Gentleman is Incredible explaining everything. I never knew any of this and I've worked on aircraft engines, most notably the metal's involved and there complexity. Thank you sir for you knowledge and your service to America.
I think he is credible, why don't you think he is?
This man has so much knowledge and does such a great job sharing that knowledge. He would be a great teacher to the next generations of engineers.
I am honored to hear this gentleman share what he can about his "job" working on water heaters.
I sat and smiled the whole time beholding his joy and pride in his job, his country and his engine.
I was the last Tech. Lead on the fuel control systems on this engine. It was the highlight of my career more than 30 years ago. The people at P&W were the absolute best people I've ever worked with. Stan Dees was the head of the program in those days.
I expected a unilateral phase detractor retro encabulator video but this guy was legit. Mad respect
What a true guy, engineer, teacher, and very passionate about his work. Well done sir!
All I can say is wow.
I'm a 60 year old turbo-prop engine mechanic that had no idea of the challenges they faced.
Thanks for this remarkable video
Thanks to whoever made this possible. This is solid gold.
Incredible!!!
The explanation of the engine's works were amazingly good... but his stories are absolutely priceless.
Being an engineer in a completely different field, I admire this guy. What an inspiring love for his work.
question mr engineear, why wouldn't a mirror close to the atmosphere, work? image they somehow get a big mirror very high up, a hot air balloon or something and then they could use a telescope [nasa grade telescope] to look at the reflection and spy on the soviets this way? could be a concaved mirror at a perfect mathematical angle. i know a satellite would be best, but if they are using planes this isnt too crazy
I'm a Air Force veteran and the SR-71 is my favorite aircraft. I enjoyed every minute of this interview.
I have but the utmost respect for this gentleman. I wish I could listen to him for all of the amazing histories he has to tell.
I would love to buy him lunch and listen to all his wonderful stories. He truly is a great engineer and loves what he was able to add to the program. His passion is contagious!
Very interesting to listen too thanks Clayt and Cath
Not enough of these geniuses get to explain their super human experiences. It was so entertaining to listen to his story.
I am not an engineer but I love planes. I could listen to this guy all day. Not just because the subject matter but because you can see his enthusiasm, passion, and pride when he explains things. He makes it easier to understand.
Incredible! As an engineer myself, the talent and skills of these guys are only something I could dream about. Such passion and knowledge to share. Just fantastic.
I'm an engineer in the power industry and for the last 20 years, I've done startups on numerous gas turbine power plants. I can't get enough of it!! Awesome video!!
This is great!! It's clear that Mr. Gunderson loved working on the J58 and the SR-71.
One of the best engines, we never were supposed to know about. My fav plane.
Thank you. An excellent talk. It is easy to tell that you loved your job and are very proud of the group's performance. I am a 71 year old USAF man, and I am proud of all of you that worked hard and excelled in your mission. Blessings.
It’s absolutely mind-boggling that the development of this legendary bird began 65 years ago. Unreal.
If this plane made its debut today it might still be considered the most incredible plane in the air.
This has got to be one of the most interesting things I've watched in a long long time. I never had the chance to go to school or work around such things, but yet I have a very good understanding of most of what he talks about here. The biggest thing that strikes me about the whole project that he points out, is that so many mundane things that I have had some experience with in my (common) life through physics, toolmaking, and engine building had created such an incredible and fascinating piece of machinery. I could converse with him for days!
This man is truly a National Treasure. Thank you Sir for your dedication.
What an absolute master art piece of engineering. The SR-71 is my favorite plane of all time, since I can remember.
What’s sad is that there is so much institutional knowledge that will be lost when these guys are gone; so much respect for the engineers. We tend to focus on the drivers and forget the many, many others that built it and made it work
I assure you that the drivers never forget the maintenance folks and the engineers. Their expertise and devotion to duty saved our lives.
My Dad was a pilot. He said the ground felt that plane was theirs. They just loaned it out to the air crew temporarily.
One take, just like that. So cool to hear engineering stories after reading so many pilot stories from the blackbird program.
Curious about engine technology today.
There's no need for something breathing air to go this fast.
Satellites do everything this plane could now, and then some.
I couldn’t care less about meeting celebrities, but I would absolutely love to buy this guy dinner and just listen to him share his experiences.
