I'm a current aerospace engineering student and the f-100 was the focus in one of our classes. The sabre dance wasn't due to loss of lift, but due to inertial coupling resulting from poor mass distribution. This channel somehow seems to keep up with the planes covered in this class and I love it!
Well, I'm not an aerospace engineering student and I don't play one on TV, but I think if go back and investigate the subject a little more thoroughly, you discover that the "Saber Dance" is indeed caused by loss of lift ... that is, loss of lift at the outer part of the wing while the inner part of the wing still lifting just fine resulting in an uncorrectable nose upward pitching moment. (I think you are confusing the "Saber Dance" with the F-100's tendency to rip itself apart in the early days because of it's undersized rudder which, thanks to inertial coupling, could very quickly lead to the aircraft yawing, pitching, and rolling at high speeds to the point where the airframe became overstressed.) All swept back wings are subject to this problem unless something is done to design it out of them, such as twisting the wings so that the outer part of the wing effectively flies at a lower AoA than the inner part, doing something to force the inner part of the wing to stall before the outer part such as through the use of stall strips, or putting fences or leading edge notches or dog tooths in to generate vortices that reduce spanwise flow towards the outer part of the wing to keep the outer part flying longer. In the case of the F-100, the "Saber Dance" was effectively fixed through the addition of a small wing fence near the training edge on the later F-100 variants (IIRC the F-100C) which I think clearly shows that inertial coupling wasn't the cause of the problem as you've apparently learned in class. And OBTW, the F-86 could also "Saber Dance", but it was never fixed ... pilot simply avoided getting into an attitude where it would occur.
That's quite interesting and indeed when I do online research your statements do seem to be the case. For the sake of continuing the conversation, I'll state where I was coming from. In my dynamics and controls class we had to derive equations of motion as they pertain to aircraft. These result in equations for pitch, roll, and yaw accelerations. The curious thing about these derived equations were terms that included motion velocities about other axes multiplied by differences in moments of inertias (for the sake of an example, the coupling term for roll rate acceleration would be [(Ixx-Izz)*roll rate*yaw rate/Iyy]. This implies that the severity of inertial coupling depends on mass imbalance. In the case of the f-100, most of the mass normally found in the wings of an aircraft (ie fuel tanks) were moved to the fuselage to allow for a thinner wing profile. These coupling terms were attributed as being the reason for the sabre dance with videos of this occurrence being shown in class. There was an emphasis on this occurring at low speeds, notably on take off with pilots being told to not use any rudder or aileron on take off to avoid this from happening.

I assume that the roll equation of motion you are referring to is: Roll p = Sum( L )/Ix - qr*(Iz - Iy)/Ix + (r + q*p)*Ixz/Ix You can find this equation and the others I suspect you derived in Volume II, "Flying Qualities Phase", Chapter 9, "Roll Coupling" put out by the USAF Test Pilot School at Edwards Air Force Base which can be found online. The equations are given, but not derived, but are used in the explanation of roll coupling, and while perhaps not as detailed in nature as what you have run into, is in a form that is more easily understood by non-aerodynamicists like me. The chapter starts by saying the following: "Divergence experienced during rolling maneuvers has frequently been referred to as 'inertial coupling.' This leads to a misconception of the problems involved. The divergence experienced during rolling maneuvers is complex because it involves not only inertial properties, but aerodynamic ones as well. [...] "There are numerous contributions to the roll coupling characteristics of an aircraft. Only three will be considered here: "Inertial Coupling "The Ixz Effect "Aerodynamic Coupling "These effects occur simultaneously in a complex fashion. Therefore, divergence cannot be predicted by analyzing these effects separately." I'll leave the rest as an exercise to the reader, and since the paper was put out in 1989, perhaps there's something in your course that is more relevant to the "Saber Dance" ... but I doubt it. From my poor dumb prospective, it seems obvious to me if you accept what the videos of F-100 "Saber Dances" show, then those "Dancing" F-100s invariably get stuck in a nose high attitude prior to their eventual demise, which means that the sum of the forces and moments acting on them all balance out to be essentially zero. Inertial coupling may lead to unexpected/unintended motions (eventually leading to a wing dropping into the ground finally causing terminal fireball), but given that the pilot is presumably fighting for control through out the "Dance", what is causing the aircraft to remain nose high no matter what in the first place? The obvious answer (and yes, I know that "obvious answers" are often times wrong) is that there is a (nose) upward pitching moment. So where does this moment come from? Well in a properly designed wing made up of non-zero pitching moment wing sections, the pitching moment of the wing is invariably nose down (at least in The Good Old Days before computers), hence the reason for the horizontal stabilizer, and so we are looking for something that can alter the pitching moment of the wing ... like what happens in the case of a tip stall of a wing with a swept back planform. So to me, the tip stalling explanation for the "Saber Dance" that I've heard (I can't remember where I first heard of it) makes intuitive sense while inertial coupling simply does not.
@@lewiscole5193 you sir are correct, and I was a crew chief on them for 8 years and 68 69 inTuy Hoa, then became a rocket engineer with a BS in Aerospace Engr in 76. It was a maintenance nightmare compared to Voodoos we got after Nam
This plane has saved my fellow vets more than you can imagine as well as me more than once, Vietnam 1968 Tet was a huge act by nva vc these planes played a big part in our battle with them Thank You hun snoot for all of us still here because of you!!!!!!
I had a Substitute Teacher from 4th to 12th grade who flew Super Sabers over Vietnam. He said he never encountered any Migs, but he would always trail off when he was asked what he did. Idk what he did, but Mr. Price was the best Sub ever.
They dropped cluster bombs on Laos and cambodia in the Rolling Thunder bombing campaign. AkA War crimes that people are still being killed to this day from😢😢 im sure he was very ashamed, "Just following orders"
I flew 6 years active duty and 15 years ANG. Like many other USAF types, I flew all three of the fighters featured in this mini-documentary, the F-100, F-105 and F-4 in the '70s and '80s. The Thud was and still is my favorite airplane. And it is by far the most beautiful. But I have known pilots who also had flown all three who held that the Hun was the most beautiful. A few of these had also flown the F-86 Sabre.
Being a Vietnam era veteran I saw some of these planes at Bien Hoa Air Base. However some of those pilots didn't care about sonic booms. I was stationed at Long Bien and seen a lot of planes over the 13 months I was there. I still love to watch planes. During 1968 TET we were real thankful for those and the Huey copters.
Dust-Off boys saved my dads life in '68, not because of enemy fire, but because his patrol had gotten lost in a rainstorm, spent 3 days in the wilderness, looking for friendlies before a couple UH-1s appeared and threw down some supplies including a map, compass, food and medical equipment until they could get to a clearing several hours later, where the same choppers could pick them up
Not trying to show my age but when I was a young kid my dad took me to a airshow at Bunker Hill Air Force base in northern Indiana. I remember seeing F-100's in Thunderbirds colors and B-58 Hustlers in the scramble hump hangars. I have heard of P-38 Droop snoot which were the P-38's with a clear B-17 nose window and a Norden bombsight with bombadier in the nose. They were used to lead formations of P-38's for group bombing of targets in Normandy before D-Day.
Ah yes, bunker hill, formerly a Naval Air Station. Then an Air Force base for B-58 hustler supersonic bombers, Now Grissom air reserve base housing a KC-135 tanker squadron.
The F-100D is literally the worst jet ever it’s 10.0 so it always gets uptiered to 10.3 and it always just gets clapped so hard because it’s a slow, fat, flying piece of useless tin.
Friso S I know, I have the Chinese one and it’s so good. The lack of any uptiers whatsoever automatically makes you top dog every game, you are always the fastest and the most heavily armed jet of the BR facing jets as low as the lowly MiG-15bis at 8.7, the only counter to it in the Hunter FGA 9 and the Lightning F. 6
Friso S No it doesn’t get AiM-9E’s, only AiM-9B’s, but I prefer having that and only getting downtiered than having slightly better missiles but much stronger and tougher opponents at 10.3
My Dad's squadron was the first to receive F 100's. They were called the mach busters. It was an itchy twitchy plane. Dangerous business that early jet ere.
Yes, the Thud was the workhorse! Had the great pleasure and honor of knowing COL Konrad Trautman, 105 pilot, who survived years in the Hanoi Hilton. A fierce patriot and true gentleman, he had a quiet strength and presence that was almost other-worldly!❤RIP
May 1968, I was in the back seat of an Air Force FAC O-1A. We were over the steep mountains West of Pleiku. Circling the mountop where US ground troops set off orange smoke. 3 or 4 tight circles, turns banked so tight, I could see the mountaintop through the plexiglass over my head. Then he would dive straight down toward the mountain and fire a WP rocket. After the second circling set and the second rocket fired at the mountain side, he flew a little further away from the ground fire that was directed at us. Luckily we were not hit. Less than a minute later two F100's flew up the canyon toward the WP smoke and released their cluster bombs. The multiple cluster bomb explosions going up the hillside maybe 300 to 500 yards each. First and last time I hitched a ride with a FAC.
When I lived on Cannon AFB a F-100 did a low level Mach 1 pass over the base. That shattered many windows on the base. My father told me the pilot lost his wings over that incident. My friend and I jumped about 3 feet of the ground when the sonic boom hit us.
Incredibles. whe I was a kid back in late 60s our family would attend the Blue Angels air show at NAS Alameda CA. F4's in formation would make low level supersonic passes and it was awesome. All you saw were like quick snapshots of these jets coming at you and over and gone and BOOM!
Cannon was our last base when my dad retired. The EF-111 were retired too. F-16s moved in. With those high empty plains, the roar of the jets traveled a long way. I remember the F-100 static display out there too. Man, that base was awful.
@@beyond_the_infinite2098 They weren’t supersonic. Probably only about 480KTAS. It just seemed supersonic because you didn’t know any better. Intentional supersonic flight in populated areas is prohibited. Even for Blue Angels and Thunderbirds.
Funny, use to hear the booms occasionally as a kid in the late 60’s and early ‘70s on our central Tx farm. Always remember the antique china cabinet in my grandparents house rattle as a result❤
I remember my father building a plastic model of an F-100 for me when I was a kid. Years later when I was in the Air National Guard I got to ride in one.
Met an F-100 pilot who flew it on a tour in Vietnam, but 2 more tours flying Cessenas as a FAC. He enjoyed this more than the F-100, but it was the first fighter he qualified for.
@@robertstack2144 Tuy Hoa was a lot better. charlie didn't mess with us much. only hit once in six months. right on the beach. Danang was huge, Air Force on one side of the runway, and Marines on the other side. we got hit with rockets a couple times a week. bigger pucker factor.
Trained on the Hun, but was assigned to RF-4C, worked around F-105s but spent most of my time on F-111A and Fs. Saw a few Canuck F-104s from Cold Lake. Still love the sounds of Jets and smell of JP-4.
The main reason why the F-100A got grounded was the fact while the prototype had a relatively tall vertical tail, the first production F-100's had a shorter vertical tail, which caused all kinds of instability issues. It wasn't until the original taller tail design was restored that the F-100 finally became a decent fighter.
One of my earliest memories is watching the Thunderbirds flying their F-100s at McChord AFB in ~1964. It must have been the low show because I remember taking cover under a C124 Globemaster II wing at one point in the day. First time I felt sound in my chest.
@@T_bone yo stfu other people can have their own opinion on what is funny. Just because your opinion is different doesn't mean it's bad. Also this comment is like 4 months old.
@5:27 "... the Migs powerful triple cannons managed to knock one super saber out of the sky...". @7:00 " thru out the conflict ... no F100s were lost to enemy aircraft..." !?!
I got confused over that, the narration makes no sense. I suppose it is a mistake done when doing this script which is probably based on several sources.
A park in Glendale AZ in which I spent a lot of time in, has one mounted on a concrete pylon. Luke AFB brought it out in the early '70's and set it up there. Still there AFAIK.
@@MakeMeThinkAgain we'd hear sonic booms nearly every day coming from out there, usually doubles. Bombing range in SW AZ Gila Bend area, probably heard a lot of noise too. 💣
I just went and saw one of the last remaining F -100s left in existence. In Ft. Wayne Indiana. Looked inside the cockpit and talked to the mechanic who regularly services the aircraft. How Cool!
I flew Grumman TR2 fixed gear single engine private planes out of Toledo Ohio and had the honor by pure chance to fly in the pattern with a ANG F-100 doing touch and Goes. I flew Left hand patterns with a 360 midway down the runway on my Downwind leg while the F-100 was flying Right hand patterns. The F-100 would do 2 T/Os for every one of mine. I was instructed by the Tower to do full throttle finals and Full Throttle take offs and climb outs. I was also required to Turn on to the Cross wind leg as soon as I concider to be at a safe altitude in order to get out of the F-100s way as he would already be on final at 140+ mph vs my ground speed of 86 mph on climb out. It was great to get in behind the 100 when it was on final and watch it fluttering like a 140+ mph falling leaf. Great experiance.
I served in Viet Nam in 1965-66 as the maintenance officer in the 416th TFS. We had F-100Ds, with one F 2 2 seater. One helluva plane, and one helluva group of guys. We were in the 3rd Tac Fighter Wing. We were first based at Tan Son Nuht. The rest of the wing was at Bien Hoa. There wasn’t enough hard surfaced ramp space there at first, so we operated from Tan Son Nuht until about March of 65, then moved to Bien Hoa. I still think about the guys I served with there, and miss the strong camaraderie. Courtesy of Half Vast Flying
I worked at a small regional airport in 74. One day alarms went off and a f-100 variant flown by airguard made emergency landing , as local base was having radar issues and he was running low on fuel. Most of our mechanics, radio men, pilots were all ex-vietnam , so we got charge examining the plane while there. It still had four 20 mm cannons, and pilot said he usually flew it around 600mph, and had mark on air speed indicator at 700mph. . When it left ,the afterburner flame looked as long as our 5k strip. I got to fly in B-17 and cobra while there.
Whila at Oshkosh Airventure in 2019, I talked to some pilots who flew the Wild Weasel mission in Viet Nam. According to them, the letters at the bottom of the patch shown at 6:14 stand for "You Gotta Be Shitting Me". Those guys are combat vets and heroes, and I believe them.
I remember having 2x Revell 1/40th Century series models - very crude by today standards - but, with the single piece pilot, seat & inst. panel carefully painted and their transfers applied - they really captured the look of the F100…!
@@superwout it means, "You Gotta Be Shitting Me" This was the reaction by most Wild Weasel pilots when they learned of the extremely dangerous nature of their mission.
My grandad flew the F-100 in Vietnam. They drew him out of retirement during the cuban missile crisis as an alert pilot - his plane armed with tactical nuclear bombs near the florida coast (which obviously never got dropped). He once had an anti aircraft shell lodged in his wing in Vietnam after a strafing run. It never went off - otherwise, I probably wouldn't exist. His squadron flew missions out of Da Nang - mostly strafing and bombing missions for ground support.
I was in Nam in '67 and my platoon accidentally strayed into Cambodia when we were spotted by two F 100's. They made several strafing runs thinking we were NVA and their cannons tore up the whole area. Fortunately, there were a lot of boulders there to hide near and no one was hurt.
One f these aircraft stood in as a Mig21 in the 1971 James Brolin movie "Skyjacked". I know this because my dad ponted it out to me. Saw in-theater, that's how old I am
"Higher then average accident rate" combined with no ground-level ejection was a killer. My next door friend's dad was killed when landing, and the plane pitched up and rolled over. My first time seeing a commander and chaplain show up at a door.
I kind of feel like the coolest Vietnam mission of the F-100 got over looked. The “Misty” Fast FAC missions were crazy and vital. I was lucky to participate in moving the last two seat F-100 from AMARG to National Guard Bureau headquarters.
From today's perspective it's impossible to imagine the level and the amount of loss that the USAF and US Navy had in their air fleets during the Vietnam War. Although now we have 70% less aircraft in our fleets, technology advancements make one Raptor, F-35 or Strike Eagle deadlier than a complete air wing of the Vietnam War aircraft. Advanced radar and order of magnitude more advanced air to air missiles also resulted in a very expensive aircraft that we fly today which could be to valuable to put into risky situations.
8:30 The USAF Thunderbirds were created in May 1953 and flew the F-100C and the F-100D Super Sabre jets. It was and still is a 5 pilots strong air demonstration acrobatic team!
Man, you have really expanded the Dark brand. I can't wait for Dark Table, a show based on the food people were eating during dark times in human history. 😆
I grew up 2 miles north of the main runway at McConnell AFB in Wichita KS. I remember watching the Thunderbirds fly their F-100s over my house every year. And yes, the "sonic boom" was always the best part of the show!
there's a Connecticut air national guard f-100 in the new England air museum and i had the honor of sitting in her. there's many beautiful aircraft there but she steals the show.
The George Welsh mentioned at 2:27 is the same 2nd Lt. George Welsh who was credited with shooting down Japanese planes during the Pearl Harbor attack, on Dec. 7, 1941. When the attack began, he and another pilot (2nd Lt. Kenneth Taylor) drove to a remote airfield and took off in a pair of P-40s. Both were awarded the DSC.
8:43 The pilots at Area 51 must have missed that memo. My uncle lives 35 minutes from the base, and his ranch gets damaged all the time from the jets going supersonic over his home. The first time I visited, I was started when a sonic boom woke me up in morning.
I'm so glad I found your Video subscription so worth it. Please keep up the great work. Also do you think we could get a video on a plane gets it's number designation
@@Rob-vv5yn There is a YTvideo about a 100 with a probable mig kill. You know that. The 100 did shoot down a jet bomber. This was not fiction and it did it with an AIM-9J missile. It was an accident. I remember when in Tuy Hoa Vietnam at the NCO club after a few too many two ANG crew chiefs got into a "your squadron can't do this, oh yeah, and you can't top this," where one of us blurted out "well at least we never shot down one of our own B-52's," which led to a brawl inside the club. The fellow squadron's pilot who I helped strap in the airplane i was crewing that flight one day, was flying the 100. He wore a metal flake blue painted helmet. His last name was like Van Synco as I can recall. Later after returning to the USA, and still crewing 100s or 101's he and thee other jocks were in the movie SKYJACKED, him wearing the blue helmet. I don't know how they got away with it.. A big red Russian Star is painted on the ctr fuselage of each 100 and you'll notice a yellow roadrunner on top of each 100's vertical fin designating the 188th NMANG
I can remember watching them perform as the Thunderbirds, at Homestead Air Force base south of Miami. They had a "hard light" afterburner, which lit off with a bang. So it made for a good airshow plane. Reading books written by pilots who flew the F-105's in Vietnam, they mentioned it had trouble keeping up with the 105's. They'd fly wild weasel for them on the way in on a mission to clear the path for them. So they slowed down for them so they could reach out in front of them. It's too bad they put the refueling probe on externally like they did, which was always hanging out in the breeze. Had to be a lot of drag.. Some later jets, like the F-14 had a retractable probe. I guess it took them a while to get that all sorted out.
@@Idahoguy10157 F-100 had 889 lost in accidents in USAF service out of 2294 built with the 193 Vietnam war combat losses that's 1082 lost over 50% of those used by the USAF since 257 new built were exported to allies. That's a higher accident loss rate than F-104's had in German service. Not that surprising for the first mass produced supersonic aircraft but still not something that you would want to fly back in the 50's or 60's.
@@Idahoguy10157 one of my earliest up close encounters with a fighter plane was with an F-100. There's one on a stick at a local park. I was mesmerized by it and wanted to know how it worked and what it took to operate it.
It never stops fascinating me just HOW MANY Cold War and Viet Nam era fighters and bombers came out in such a short duration of time. Love this channel, please keep filling my brain with information. Your whole thing reminds me of the Discovery and History Channels that I grew up with in the 80's and 90's.
I was going to suggest you cover the Century Series... but you did it right at the end. Still, maybe a comparison of the various aircraft would be interesting.
A historically important aircraft. Although one with a kind of scary service history. I think it says all you need to know, that the Air Force looked at their F-100’s in combat, then noticed the F4 Phantom’s the Navy was flying and said “can we order a ton of those?” The F-100 was a transitional plane. It’s replacement, the F-4 was arguably one of the greatest aircraft ever built and may have been the longest serving fighter aircraft worldwide. With some specimens only leaving frontline service in the 2010’s.
Capt. John Boyd USAF, an instructor pilot at the USAF Fighter Weapons School (which the Navy instituted as Top Gun), showed that the reason so many pilots were lost in the Hun was adverse yaw at low airspeed and high angle of attack. After that pilots were taught how to avoid it and many fewer Huns crashed.
At 5:28 it says, "...the MIG's powerful triple cannons managed to knock one Super Saber out of the sky and severely damaged another." Then at 7:00 it says, "No F-100 were lost to enemy aircraft." Seems to be a bit of a contradiction.
At least a couple other people have already noted this in the comments. To clarify, the narrator misspoke mixing up what happened with the F-100s and F-105s during the attack. In the April 1965 raid against the Thanh Hoa (AKA "Dragon's Jaw") bridge, a bunch of F-100s accompanied a bunch of F-105s where the former were acting as cover and the latter were effectively acting as bombers targeting the bridge. A bunch of MiG-17s blew passed the F-100s and attacked the F-105s with the result being that one F-105 was shot down right away while another was damaged but managed to escape only to crash before it made it back to base. Some of the F-100s attempted to engage the MiG-17s and one of the F-100 pilots, Don Kilgus, claims that he shot down one of the MiG-17s, but officially, this kill was never acknowledged. No further engagements took place throughout the war between any Vietnamese MiGs and F-100s and so officially no F-100s were ever lost in air combat and no F-100s made any aerial kills either. For more information on the attacks on the Thanh Hoa bridge, you can look at the Wikipedia entry for the bridge which can be found here: < en.wikipedia.org/wiki/Thanh_H%C3%B3a_Bridge >

I assume that the roll equation of motion you are referring to is:
Roll p = Sum( L )/Ix - qr*(Iz - Iy)/Ix + (r + q*p)*Ixz/Ix
You can find this equation and the others I suspect you derived in Volume II, "Flying Qualities Phase", Chapter 9, "Roll Coupling" put out by the USAF Test Pilot School at Edwards Air Force Base which can be found online.
The equations are given, but not derived, but are used in the explanation of roll coupling, and while perhaps not as detailed in nature as what you have run into, is in a form that is more easily understood by non-aerodynamicists like me.
The chapter starts by saying the following:
"Divergence experienced during rolling maneuvers has frequently been referred to as 'inertial coupling.' This leads to a misconception of the problems involved. The divergence experienced during rolling maneuvers is complex because it involves not only inertial properties, but aerodynamic ones as well. [...]
"There are numerous contributions to the roll coupling characteristics of an aircraft. Only three will be considered here:
"Inertial Coupling
"The Ixz Effect
"Aerodynamic Coupling
"These effects occur simultaneously in a complex fashion. Therefore, divergence cannot be predicted by analyzing these effects separately."
I'll leave the rest as an exercise to the reader, and since the paper was put out in 1989, perhaps there's something in your course that is more relevant to the "Saber Dance" ... but I doubt it.
From my poor dumb prospective, it seems obvious to me if you accept what the videos of F-100 "Saber Dances" show, then those "Dancing" F-100s invariably get stuck in a nose high attitude prior to their eventual demise, which means that the sum of the forces and moments acting on them all balance out to be essentially zero.
Inertial coupling may lead to unexpected/unintended motions (eventually leading to a wing dropping into the ground finally causing terminal fireball), but given that the pilot is presumably fighting for control through out the "Dance", what is causing the aircraft to remain nose high no matter what in the first place?
The obvious answer (and yes, I know that "obvious answers" are often times wrong) is that there is a (nose) upward pitching moment.
So where does this moment come from?
Well in a properly designed wing made up of non-zero pitching moment wing sections, the pitching moment of the wing is invariably nose down (at least in The Good Old Days before computers), hence the reason for the horizontal stabilizer, and so we are looking for something that can alter the pitching moment of the wing ... like what happens in the case of a tip stall of a wing with a swept back planform.
So to me, the tip stalling explanation for the "Saber Dance" that I've heard (I can't remember where I first heard of it) makes intuitive sense while inertial coupling simply does not.

I had a Substitute Teacher from 4th to 12th grade who flew Super Sabers over Vietnam. He said he never encountered any Migs, but he would always trail off when he was asked what he did. Idk what he did, but Mr. Price was the best Sub ever.
They dropped cluster bombs on Laos and cambodia in the Rolling Thunder bombing campaign. AkA War crimes that people are still being killed to this day from😢😢 im sure he was very ashamed, "Just following orders"
The F-100 had great lines, really a beautiful plane.
I flew 6 years active duty and 15 years ANG. Like many other USAF types, I flew all three of the fighters featured in this mini-documentary, the F-100, F-105 and F-4 in the '70s and '80s. The Thud was and still is my favorite airplane. And it is by far the most beautiful. But I have known pilots who also had flown all three who held that the Hun was the most beautiful. A few of these had also flown the F-86 Sabre.
@@daveriley6310 thank you sir
It's a nice plane yes, very well balanced design. F-86 had something more elegant to my eyes, but well, I like both.
Being a Vietnam era veteran I saw some of these planes at Bien Hoa Air Base. However some of those pilots didn't care about sonic booms. I was stationed at Long Bien and seen a lot of planes over the 13 months I was there. I still love to watch planes. During 1968 TET we were real thankful for those and the Huey copters.

Dust-Off boys saved my dads life in '68, not because of enemy fire, but because his patrol had gotten lost in a rainstorm, spent 3 days in the wilderness, looking for friendlies before a couple UH-1s appeared and threw down some supplies including a map, compass, food and medical equipment until they could get to a clearing several hours later, where the same choppers could pick them up

Not trying to show my age but when I was a young kid my dad took me to a airshow at Bunker Hill Air Force base in northern Indiana. I remember seeing F-100's in Thunderbirds colors and B-58 Hustlers in the scramble hump hangars.
I have heard of P-38 Droop snoot which were the P-38's with a clear B-17 nose window and a Norden bombsight with bombadier in the nose. They were used to lead formations of P-38's for group bombing of targets in Normandy before D-Day.
Ah yes, bunker hill, formerly a Naval Air Station. Then an Air Force base for B-58 hustler supersonic bombers, Now Grissom air reserve base housing a KC-135 tanker squadron.

The F-100D is literally the worst jet ever it’s 10.0 so it always gets uptiered to 10.3 and it always just gets clapped so hard because it’s a slow, fat, flying piece of useless tin.
@@rosstheboss1014 French and Chinese ones are 9.7 and just better because no uptiers.
Friso S I know, I have the Chinese one and it’s so good.

I was a Crew Chief on them in the Air Force. We used to call it the "Triple Threat". It could bomb you, strafe you or fall on you.
My Dad's squadron was the first to receive F 100's. They were called the mach busters.
It was an itchy twitchy plane. Dangerous business that early jet ere.
Ya my dad worked at DeHavilland in England when the Vampire was being tested.
I know the F-4 is most associated with the Vietnam war but the F-100 was the Vietnam workhorse.
And not the 105?
More like the F-105 thud, she did nearly 70% of all sorties in Rolling Thunder along with being a wild weasel plane too.
Yes, the Thud was the workhorse! Had the great pleasure and honor of knowing COL Konrad Trautman, 105 pilot, who survived years in the Hanoi Hilton. A fierce patriot and true gentleman, he had a quiet strength and presence that was almost other-worldly!❤RIP
May 1968, I was in the back seat of an Air Force FAC O-1A. We were over the steep mountains West of Pleiku. Circling the mountop where US ground troops set off orange smoke. 3 or 4 tight circles, turns banked so tight, I could see the mountaintop through the plexiglass over my head. Then he would dive straight down toward the mountain and fire a WP rocket. After the second circling set and the second rocket fired at the mountain side, he flew a little further away from the ground fire that was directed at us. Luckily we were not hit. Less than a minute later two F100's flew up the canyon toward the WP smoke and released their cluster bombs. The multiple cluster bomb explosions going up the hillside maybe 300 to 500 yards each. First and last time I hitched a ride with a FAC.
6:14 YGBSM = You gotta Be Shitting Me. We had the same acronym on our F-111's nose gear doors.
When I lived on Cannon AFB a F-100 did a low level Mach 1 pass over the base. That shattered many windows on the base. My father told me the pilot lost his wings over that incident. My friend and I jumped about 3 feet of the ground when the sonic boom hit us.
Incredibles. whe I was a kid back in late 60s our family would attend the Blue Angels air show at NAS Alameda CA. F4's in formation would make low level supersonic passes and it was awesome. All you saw were like quick snapshots of these jets coming at you and over and gone and BOOM!
Cannon was our last base when my dad retired. The EF-111 were retired too. F-16s moved in. With those high empty plains, the roar of the jets traveled a long way. I remember the F-100 static display out there too. Man, that base was awful.
@@beyond_the_infinite2098
They weren’t supersonic. Probably only about 480KTAS. It just seemed supersonic because you didn’t know any better.
Intentional supersonic flight in populated areas is prohibited. Even for Blue Angels and Thunderbirds.
Funny, use to hear the booms occasionally as a kid in the late 60’s and early ‘70s on our central Tx farm. Always remember the antique china cabinet in my grandparents house rattle as a result❤
I love hearing stories from my uncle about flying this in Vietnam. He always ends each story with "THAT WAS 50 YEARS AGO!"
The first Monogram 1/48th scale aircraft I ever built. Loved this plane.
I remember my father building a plastic model of an F-100 for me when I was a kid. Years later when I was in the Air National Guard I got to ride in one.
@@joevignolor4u949 That is kick ass!
@@TheDing1701 Actually I got two rides in an F-100. So it was double kick ass. Both were air-to-air combat missions dogfighting with other aircraft.

Met an F-100 pilot who flew it on a tour in Vietnam, but 2 more tours flying Cessenas as a FAC. He enjoyed this more than the F-100, but it was the first fighter he qualified for.

Your Grandfather was cool! You should feel proud.
The main reason why the F-100A got grounded was the fact while the prototype had a relatively tall vertical tail, the first production F-100's had a shorter vertical tail, which caused all kinds of instability issues. It wasn't until the original taller tail design was restored that the F-100 finally became a decent fighter.
One of my earliest memories is watching the Thunderbirds flying their F-100s at McChord AFB in ~1964. It must have been the low show because I remember taking cover under a C124 Globemaster II wing at one point in the day. First time I felt sound in my chest.

That confused me too, Maybe it was knocked out of combat. Couldn't fight but it still flew back to base.
I got confused over that, the narration makes no sense. I suppose it is a mistake done
when doing this script which is probably based on several sources.
USAF never accepted that they lost any aircraft in air combat only to flak and SAM's.
A park in Glendale AZ in which I spent a lot of time in, has one mounted on a concrete pylon. Luke AFB brought it out in the early '70's and set it up there. Still there AFAIK.
Would be interesting to see a history of Luke and the aircraft flown from there. Lots of 104s, speaking of the Century Series.
@@MakeMeThinkAgain we'd hear sonic booms nearly every day coming from out there, usually doubles. Bombing range in SW AZ Gila Bend area, probably heard a lot of noise too. 💣
In high school a friend’s step-father was a retired Major who flew the F-100 in combat
I just went and saw one of the last remaining F -100s left in existence. In Ft. Wayne Indiana. Looked inside the cockpit and talked to the mechanic who regularly services the aircraft. How Cool!
I flew Grumman TR2 fixed gear single engine private planes out of Toledo Ohio and had the honor by pure chance to fly in the pattern with a ANG F-100 doing touch and Goes. I flew Left hand patterns with a 360 midway down the runway on my Downwind leg while the F-100 was flying Right hand patterns. The F-100 would do 2 T/Os for every one of mine. I was instructed by the Tower to do full throttle finals and Full Throttle take offs and climb outs. I was also required to Turn on to the Cross wind leg as soon as I concider to be at a safe altitude in order to get out of the F-100s way as he would already be on final at 140+ mph vs my ground speed of 86 mph on climb out. It was great to get in behind the 100 when it was on final and watch it fluttering like a 140+ mph falling leaf. Great experiance.
My family saw the Thunderbirds flying the F-100s at Forbes AFB in 1968 when my dad was stationed there. Great show and airplane.
I served in Viet Nam in 1965-66 as the maintenance officer in the 416th TFS. We had F-100Ds, with one F 2 2 seater. One helluva plane, and one helluva group of guys. We were in the 3rd Tac Fighter Wing. We were first based at Tan Son Nuht. The rest of the wing was at Bien Hoa. There wasn’t enough hard surfaced ramp space there at first, so we operated from Tan Son Nuht until about March of 65, then moved to Bien Hoa.
I still think about the guys I served with there, and miss the strong camaraderie.

i was with the 416th in 1970.
I worked at a small regional airport in 74. One day alarms went off and a f-100 variant flown by airguard made emergency landing , as local base was having radar issues and he was running low on fuel. Most of our mechanics, radio men, pilots were all ex-vietnam , so we got charge examining the plane while there. It still had four 20 mm cannons, and pilot said he usually flew it around 600mph, and had mark on air speed indicator at 700mph. . When it left ,the afterburner flame looked as long as our 5k strip. I got to fly in B-17 and cobra while there.

The F100 is the jet that you think of when you think about Cold War era supersonic aircraft, with it’s swept back wing design, it’s an iconic image
one of my all time jets. to me it just looks like a jet always in motion and ready to fight. A beautiful piece of machinery
I remember having 2x Revell 1/40th
Century series models - very crude by today standards - but, with the single piece pilot, seat & inst. panel carefully painted and their transfers applied - they really captured the look of the F100…!
As a young teen in the mid-60s, this was my favorite fighter aircraft! Visually, it is STILL a beautiful jet!
Theres an incredibly good documentary called "Hun Pilots" with interviews of the first pilots of the F-100. Highly recommend it.

My grandad flew the F-100 in Vietnam. They drew him out of retirement during the cuban missile crisis as an alert pilot - his plane armed with tactical nuclear bombs near the florida coast (which obviously never got dropped). He once had an anti aircraft shell lodged in his wing in Vietnam after a strafing run. It never went off - otherwise, I probably wouldn't exist. His squadron flew missions out of Da Nang - mostly strafing and bombing missions for ground support.
"brought to you by warthunder"
*cry in F-100 suffering*
I was in Nam in '67 and my platoon accidentally strayed into Cambodia when we were spotted by two F 100's. They made several strafing runs thinking we were NVA and their cannons tore up the whole area. Fortunately, there were a lot of boulders there to hide near and no one was hurt.

I was lucky to participate in moving the last two seat F-100 from AMARG to National Guard Bureau headquarters.
From today's perspective it's impossible to imagine the level and the amount of loss that the USAF and US Navy had in their air fleets during the Vietnam War. Although now we have 70% less aircraft in our fleets, technology advancements make one Raptor, F-35 or Strike Eagle deadlier than a complete air wing of the Vietnam War aircraft. Advanced radar and order of magnitude more advanced air to air missiles also resulted in a very expensive aircraft that we fly today which could be to valuable to put into risky situations.
8:30 The USAF Thunderbirds were created in May 1953 and flew the F-100C and the F-100D Super Sabre jets. It was and still is a 5 pilots strong air demonstration acrobatic team!

I’ve seen one of the privately-owned Super Sabres here in Michigan. Single stage AB, startled a friend of mine during an airshow.
I grew up in Columbus, Ohio and remember the sonic booms from the F-100s at Lockbourne AFB (LCK)
It was aboard of one of those jets a test pilot have been doing the first ejection above the speed of sound.
He was badly injured but surviving
I grew up 2 miles north of the main runway at McConnell AFB in Wichita KS. I remember watching the Thunderbirds fly their F-100s over my house every year. And yes, the "sonic boom" was always the best part of the show!

@@robertstack2144 interesting story please explain always interested in history
@@Rob-vv5yn There is a YTvideo about a 100 with a probable mig kill. You know that. The 100 did shoot down a jet bomber. This was not fiction and it did it with an AIM-9J missile. It was an accident. I remember when in Tuy Hoa Vietnam at the NCO club after a few too many two ANG crew chiefs got into a "your squadron can't do this, oh yeah, and you can't top this," where one of us blurted out "well at least we never shot down one of our own B-52's," which led to a brawl inside the club. The fellow squadron's pilot who I helped strap in the airplane i was crewing that flight one day, was flying the 100. He wore a metal flake blue painted helmet. His last name was like Van Synco as I can recall. Later after returning to the USA, and still crewing 100s or 101's he and thee other jocks were in the movie SKYJACKED, him wearing the blue helmet. I don't know how they got away with it.. A big red Russian Star is painted on the ctr fuselage of each 100 and you'll notice a yellow roadrunner on top of each 100's vertical fin designating the 188th NMANG
I can remember watching them perform as the Thunderbirds, at Homestead Air Force base south of Miami. They had a "hard light" afterburner, which lit off with a bang. So it made for a good airshow plane. Reading books written by pilots who flew the F-105's in Vietnam, they mentioned it had trouble keeping up with the 105's. They'd fly wild weasel for them on the way in on a mission to clear the path for them. So they slowed down for them so they could reach out in front of them. It's too bad they put the refueling probe on externally like they did, which was always hanging out in the breeze. Had to be a lot of drag.. Some later jets, like the F-14 had a retractable probe. I guess it took them a while to get that all sorted out.

The "Sabre Dance"
HighFlyer .... all of the century series aircraft had issues
@@Idahoguy10157 F-100 had 889 lost in accidents in USAF service out of 2294 built with the 193 Vietnam war combat losses that's 1082 lost over 50% of those used by the USAF since 257 new built were exported to allies.
That's a higher accident loss rate than F-104's had in German service.

Love all the P-51 film 🎥 while you’re talking about F-100 Super Sabres.
The first aircraft I ever crewed in the AF. I remember well when they were being returned from SE Asia to the states. Many were shot up.
I used to think the F-84 was better looking, however the F-100 has really grown on me and I think it’s definitely the sleeker plane...what a beauty!
@darkskies you’ve gotta do a video on the A-10 if you end up doing another close air support aircraft. 👌🏼
Beautiful aircraft. Such perfectly simple lines, a classic early cold war jet fighter
At a museum I was able to sit in a decoy cockpit of it and it was amazing.
I was going to suggest you cover the Century Series... but you did it right at the end. Still, maybe a comparison of the various aircraft would be interesting.
I always liked the 100 from when I first read about it as a little kid loving military aviation.
A historically important aircraft. Although one with a kind of scary service history. I think it says all you need to know, that the Air Force looked at their F-100’s in combat, then noticed the F4 Phantom’s the Navy was flying and said “can we order a ton of those?” The F-100 was a transitional plane. It’s replacement, the F-4 was arguably one of the greatest aircraft ever built and may have been the longest serving fighter aircraft worldwide. With some specimens only leaving frontline service in the 2010’s.
PLEASE DO MORE OF THESE VIETNAM WAR ERA PLANES!
I like how some of the first footage of "F-100" production in the first couple of minutes are actually of P-51s, lol
Capt. John Boyd USAF, an instructor pilot at the USAF Fighter Weapons School (which the Navy instituted as Top Gun), showed that the reason so many pilots were lost in the Hun was adverse yaw at low airspeed and high angle of attack. After that pilots were taught how to avoid it and many fewer Huns crashed.
At 5:28 it says, "...the MIG's powerful triple cannons managed to knock one Super Saber out of the sky and severely damaged another."
Then at 7:00 it says, "No F-100 were lost to enemy aircraft."
Seems to be a bit of a contradiction.
At least a couple other people have already noted this in the comments.
To clarify, the narrator misspoke mixing up what happened with the F-100s and F-105s during the attack.
In the April 1965 raid against the Thanh Hoa (AKA "Dragon's Jaw") bridge, a bunch of F-100s accompanied a bunch of F-105s where the former were acting as cover and the latter were effectively acting as bombers targeting the bridge.
A bunch of MiG-17s blew passed the F-100s and attacked the F-105s with the result being that one F-105 was shot down right away while another was damaged but managed to escape only to crash before it made it back to base.
Some of the F-100s attempted to engage the MiG-17s and one of the F-100 pilots, Don Kilgus, claims that he shot down one of the MiG-17s, but officially, this kill was never acknowledged.
No further engagements took place throughout the war between any Vietnamese MiGs and F-100s and so officially no F-100s were ever lost in air combat and no F-100s made any aerial kills either.
For more information on the attacks on the Thanh Hoa bridge, you can look at the Wikipedia entry for the bridge which can be found here:
