the day Grant passed away and it was announced, I shed a tear!he had so much fun with Tori and Kari!
Grant was the best of them imho. He really knew his shit and was thoroughly entertaining whilst explaining it all.
@@Rich77UK he was also on one of the cool tv shows when I moved here to denmark!Robot Wars on tv 2 Zulu!which he dominated!
Was about to say "I dont want to watch the Jato-episodes - Ive already recently watched both!". Never watched anything beyond season 8 back in the day, so very happy to learn that they did it a third time and that I didnt watch this one before!
You know the saying, third time's a charm
Forgot this episode existed.
Many TV channels.. simplydidnt wanted to be taken for that ride. that Mythbusters producers tried at the last few years of the shows era...
You can see it in an episode like this.. the majority is just old clips and postedit fluff..
Very little actual content... it was a moneymachine and the quality of the content had very little bearing... why many TV channels said no, and didn't purchase it.
Samre with "there your problem" episodes that also was old content, flipped and trying to be sold again..
same with "outtakes" that really wasn't outtakes and almost no meat on the bone, and mostly Adam & Jamie standing and destroying VHS tapes in 90 different ways.
Discovery new Mythbusters producers. that controlled the show in the later era.. was ported from some of Discovery reality TV shows where the moral bar on quality content, had no meaning.
That really hurt "Mythbuster" and why many viewers were okay with that show, being closed as it was drifted so far from the org.
Adam talks about it from time to time on his channel, though never mentions the discovery producers that dictated that sad direction.
@@JAKOB1977 Hadn't known that. thanks. Can can really see the drop off, even without the build team. Loved the earlier/mid episode in which they co-operated and did their own things, as well. Crazy still to this day people have questions about the show on Adam channel. Mythbusters inspired me in a scientific/critical(?) thinking way, but his channel inspired me in another "Artistic/maker" way... Hasn't changed much either, love his enthusiasm for what he does!
Exactly the same here
it still make me sad to see that car destroyed albe it in a glorius way
Indeed they could of used a Kia 😢
1. A curved ramp would have been more effective. You can see the physics in action in the side views. Hitting a straight ramp that steep _does_ get the front end pointed upwards, but when the rear wheels impact the ramp, it rotates the car forwards as it goes airborne. This also happens with a curved ramp, but it's less pronounced.
2. The rockets needed to be tilted forward a bit and/or positioned slightly lower. When they kicked in, the _front_ suspension compressed, suggesting the thrust was directed - or positioned - _over_ the car's centre of gravity. By directing the thrust _below_ the centre of gravity, the rear suspension would tend to compress instead of the front, partly/fully/over compensating for the forward rotation from the ramp.
Still. They made a car fly with rockets. _In real life._ That's straight up video game stuff that they actually got to do _at work._
Nah. The rockets were right. The big heavy steel bar at the front was the problem.
I agree. I recon if the road dipped down and curved up and hit the ramp. That car would have gone far
Yeah. The car barely touched the ramp and already had a downward trajectory at the end of it.
@@BabyMakR And engines are heavy as f#ck! Glad others see it.
@@BabyMakR right, but you can choose to compensate for that additional weight up front by rotating the rockets forward.
30:17 I love that the boys are super chuffed and Kari's just like, "phew"
After WWII the Granatelli brothers (Andy was head of STP later on) bought a bunch of surplus JATO rockets and a pre-war Grand Prix car which is where the 'myth' might have come from. The car had a cylindrical body so they chopped the tail and installed concentric rings of the rockets and had a dozen or so all wired to buttons on a panel for the driver to activate. Test day came and Andy was behind the wheel while the brothers followed in their Ford sedan. When he got up some speed...he hit a button and the rocket spewed some flame and smoke...but little thrust and they were disappointed....and the thought that it was a dud never crossed their minds.
So in frustration Andy hit all the rest of the buttons thinking it would make a better show...and the rest were NOT duds and the little car took off. He said he could see the bright light behind him from all the exhaust and the car got airborne enough to pass over a truck up the road a ways. Somebody did the weight/drag/thrust calculations that I don't remember off hand but something on the order of a quick 300 mph was possible. Somehow the car came down on its' wheels and rolled to a stop.
Andy was terrified that he'd immolated his brothers but in a few minutes they came up the road in the Ford. Grill melted, windshield mottled and paint all burned off the front end with the radiator leaking from the melted solder joints...but everyone was OK. Wondering if this isn't also the origination of the decorative flames on hot rods? Anyway...the whole story and many more are in Andy Granatelli's autobiography.
Takes me back to when I could "disconnect" from my daily worries and just chill with Mythbusters. ❤❤❤
it always hurts seeing old cars in good condition get destroyed
they're going to hell for this
@@armandmunoz3089 lol you need to calm down bud
I do kinda wish there had been one last attempt as part of the final season where they balanced the CG of the car to get it to go a little further and with even more power with a slightly better ramp. It's probably not going to go *that* much further because it'll get aerodynamically unstable if it goes too fast but it pitches over in this one because the CG is too far forward by a little, not helped by the bounce too soon on the ramp. Balancing the CG is really hard as they're right you don't want it too far back but too far forward is also bad for distance.
It was a good place to close the myth though to be fair, and hearing Adam talk about how he feels on it makes me okay with the result, I just personally *really* want to see a JATO car actually do a JATO for more than a few feet
Same, noticed it drive immediately. That steel bar wasn't a great idea after all, was thinking to myself "Engines are pretty heavy... I don't know Was a good attempt and yes! Would have been amazing for the one of the finales! Forgot all about this episode.
@@DarkGodSeti Yeh. The rockets are heavy at the start but then are just steel tubes after they're burnt out. One person could have carried all 6 of those tubes in one trip without the grain in them. That's why the second one pitched down like it did. If the heavy bar wasn't on the front, it would have gone further before squashing.
100% agree.. a much longer ramp (or potentially a curved, solid ramp that used the suspension “squat” - see “car backflips”), where they’re firing the rockets while already on the ramp would have given them a much better chance, but ultimately the CG was the main issue with this one.
Love to see a do over with out the front counter weight.. had it not been balance the power at the arse end , and an upward pointed nose may have been different
The last car would have flown quite a ways if not for the rocket powered face plant into the dirt. It just had too much forward rotation coming off that damn ramp. I would've love to have seen this continue like a series where they progressively get better results. A car space program if you will.
"When this baby hits 88 mph..."
Wait a minute. I've heard this before!
As the car hit the ramp the front right steering and suspension took damage and partially collapse (highly likely when you effectively hit a kerb at 200 mph). The car veered left, the front right dug in and the rolled, then flipped.
The ramp run was hampered by a lack of speed. Supposed to be doing 88 mph at rocket ignition, but it nearer 45mph. Once on the ramp, the suspension bottomed out and the underside of the car ripped up the ramp. Once off the ramp the additional mass welded to the front fender dipped the nose and that was that. Too slow, too much mass, too soft suspension and CofG too far forward.
"Mythos testos"!🤣😂🤣😂🤣
Made my day! 😎👍
Try to run it on railroad with parallel wheels upside down and it will easy because of driver less and it will never disballance the car then it will reach on maximum speed 😊
“Is that a rocket in your pocket or are you just happy to see me” 😂
Awesome watch, but what would it take to fly the car into the mountain guys. That would be the true myth busting style and an epic historic ending to this myth. Observation-loose the front counter weight and give the rockets a controllable rear up-down tilt of 6-8 inches to control the trajectory of the vehicle in flight. We would all love to see that car fly
The back shot of the white car’s wheels reminded me a lot of “Back To The Future” when Marty travels through time!
You know it's about to get crazy when all mythbusters crew member are together....love your show. Piece ✌🏽
Holy fk, only ever seen the blue comment on tiktok😮
Now the blue shit 8s gone :(
Awesome!
I remember reading about the urban legend of the "JATO rocket-car" in (I think) "Wired" magazine back around 2000 or so.
It was *hilarious!* The article went on for about 4 or 5 pages and it was one of the best-ever articles in "Wired"!
3:32 probably one of the more wholesome moments of this entire show :D
As a former R/C car enthusiast/racer I can't believe Grant preferred a stick over a pistol wheel setup. Breaks my heart.
Grant was used to stick remotes from his Battlebot days. He was very precise without a wheel
@@asicdathens I know, but no matter how proficient one can get with sticks, for cars pistols can't be beat. I raced R/C cars and never saw anyone use sticks. Planes and helicopters (and skid steer battlebots) would be the opposite. Not a pistol in sight. That and too much steering dialed in made the thing "a challenge". 😀
Its really fun; I loved this show! But for me, to be busted, one would need to know the exact JATO rocket model used, and reproduce how he attached it to the car back in 1970. In 1981 my shop teacher told me this story and I still believe it flew into the mountain side....
Yeah... I would've preferred that they didn't need to put a lot of weight in front of the car; either half of it or none at all.
So that the rocket could thrust it at an incline because once it goes down, it's over.
I bet it would've went further.
Great show. Perfect ending.
These guys always balls it up. Great concept for a show though.
i always wondered how they can just detroy that pimped up impala or how did it even end in scrapyard? that's insane! even if i had billions, i would never destroy a car like that
Adding weight to the front didn't work :(
Made it worse, since it'll just make it so the car starts pointing downwards when it goes in the air
I can tell you now the first white car with that weight on the front will not fly. But hey what the f**k do i know, it will flip and roll over . The red car will not fly either, it will drop like a stone, after the ramp.
Knew i was going to be right.
Any ramp will unfortunately cause an upset in the chassis. It needs to be sent up a long straight hill in order to stabilize its trajectory. I've jumped a few cars. The best jumps were over the top of a hill.
Yeah, these guys put an amazing amount of tech in this , but overlooked physics and mechanical engineering .
Kinda fun to see the MOMO Logitech wheel that they taped over so you can't see the logo. Also they put bolts through the original mounting clamp holes.
That was my first sim wheel and I'd know that button pattern anywhere.
Why not use a length of old railroad tract and latch it to the rail and send it down the rail into the ramp, they launch cars on rails in Alaska for fun sending cars off a clift
These guys must have gotten their training at Boeng
10 billion people = HATE YOU FOR DESTROYING A GREAT CAR =
Don't be so delusional. Are you going to say it was the greatest car GM ever built?
@@michaelbyrnee9584 ya not like a 67 stingray with a 427 or a yenko super camaro
its a 1973 malaise era impala they made 620000 of them
Those JTOS made such a cool noise
That was really spectacular and entertaining! No doubt!👍
It could have been even more if it actually flew... Uhm... you wanna give it one more try? Perhaps? Ok, here is what you need:
1. get the CG right in all 3 dimensions! (has been mentioned often enough in the comments already, though)
2. bundle the rocket motors as compact as possible, not in a 1x6 line. For a sixpack a 2x3 resp. 3x2 constellation would work. Ideally you would mount a seven-pack in a honeycomb constellation.
3. align the resulting thrustvector axis of that rocket motor pack exactly on a straight line to that CG
4. considering aerodynamic effects, a slight pitch-up of some 1° might be helpful (better ending up in pulling wild loops towards the sky than to the ground, right? ;) )
5. ramp: curved! (as already mentioned in the comments)
6. car suspension: as the bumps on the passage to the ramp add some serious angular momentum, the dampers should be set to max performance, especially on the rebound. The wobbly limousine setting of the dampers has almost nothing to oppose to that momentum. A curved ramp lowers this impact. You should find some adjustable dampers where you can set the rebound in motor sport accessories stores. Harder springs would also help.
I guess these suggestions are all I can offer to make it "fly" (better) when "aerodynamic helpers" are considered cheating. Key to success is the precision on determining CG and thrust vector alignment. This is basically a ballistic object with 3 (6) degrees of freedom all of which have to be tamed. However, at that speed aerodynamics count, too! So, bringing the car in a slightly pitched-up attitude towards the thrust vector could bring in a stabilizing effect - as long as the rockets push, of course! (CG vs CP) After that it's "wind's bride" - huiiiiii :D Maybe you wanna give it a try, I'd really love to see it fly! Good luck! 😍
adam failed to steer well! he lost focus, but jamie have more focus on the job at hand.
23:00 that sound like a skill issue :)
All the arm chair engineers are in here trying to tell a channel full of bootleg Mythbusters episodes what they did wrong like 15 years ago. Meanwhile, I’m sitting here enjoying a bittersweet memory. Sweet because it reminds me of a simpler time in my life. Bitter because, even if Mythbusters did a reunion (very unlikely), we will never, ever see these 5 together again. I am very fortunate to have gotten to see all of them in person.
Those two shorts: The five looking from the top of the ramp, and the five walking away from the sun; those images are etched in my memory as THE Mythbusters shots
Sorry guys but both cars were far to front heavy as demonstrated by the speed of the nose dive the moment the second car left the ramp!
Wrong, it's not about nose being heavy, though if it's preferable if you have stabilizers in the back it's about thrust vector being exactly at the center of gravity.
@@YPogorelov Perhaps but while the myth says the rocket engine was simply "strapped to the impala" it makes no mention of any modifications beyond that. While they are getting closer to the reproducing the results mentioned in the official police report it's clear that they still have more to do. As for the distance covered by the car once airborne this is probably down to guesswork or possibly unreliable witness reports. The only fact known to be true was that the car did hit half way up the cliff face. The difficulty they had controlling the car may have also been a factor that could have caused the car to leave the road before going airborne. From what I remember in America most roads away from the city have ditches that vary in depth and gradient some of these could have acted similar to the ramp they used. With everything the team have learned over the years I do believe that if they could get a copy of the original police report and see the pictures while studying the actual crash site and local vicinity they should now be able to show what really happened on that fateful day and finally lay this to rest. I look forward to their next attempt to perhaps they can finally close this legendary myth.
It wasn't so much about weight as the springs from the suspension causing it to bounce. I promise you, without the springs in play, there was a far better chance of straight flying
34:08 that's exactly how i do things and that's what i'd say. everything I BUILD, lasts a life time and then some.
my gaming chair's arm rests were flimsy and tiny, one broke off. i built them myself, i used pieces of wood to make them nice and wide, i put some carpet underlay on it to make it soft, then i took some leather off of old sofa and put that over, then i used flat pieces of steel and attached them to bottom of chair.
it's been about 8 years and it's still standing and i use my PC every day.
while all the default / stock stuff, like cars, chairs ..etc are falling apart so easily.
The center line of the rocket's thrust was higher than the centerline of the car's mass. So it tumbled forward. Needed a control spoiler.
Serious Mad-Max stuff....
Yeah... or the other Max...
_Carmageddon_ comes to mind...
Great game
I'm thinking more A-Team than mad max.🤔
Should have removed the springs from the suspension to avoid the flipping. Oh well, it was still fun to watch.
Ths gaise are The Best in The Tube💪💪👍👍👍
The amount of cool cars the mythbusters have cut up and crashed is beyond me 😂🤌
If only they'd have put the rockets lower, at or below the center of gravity...it would have nosed up and really flew.
34:21 the front fell off!
That's not very typical, I'd like to make that point.
That vintage of car is not unibody and is body on frame, so you can actually unbolt the entire front bodywork and it will come off in one piece
@@klonkrieger43 hit a wave....
I suggest a Jeto 4 with RC wings
Then it wouldn't be a car would it
Can we petition Ncap to include "rocket cars on a ramp" tests?? Please??
Nobody's talking about the speed rating of the tires ?
Just what I thought, as soon as the wheels leave the ground, the rockets want to overtake the car with a backflip, front flip or a side flip. A side flip it was
both attempts would work betterand be closer to the myth if not for Jamie's "proper balance"
First time watching mythbusters and they make me feel like they're from national geographic
Absolutely awesome 💯😎😎😎 and crazy ass well greatest show
Think the ramp failure kinda kicked the back of the car up a bit and that's what caused the rotation, nose down. When you jump a dirt bike you always want a nose up attitude, trust me nose down usually hurts you and you CC!
For me carnage is removing dried out concrete in a cement truck with few hundred pounds of explosives - one minute I see a cement truck then its like magic its gone!
The camber was all out of whack on that car, no wonder it couldn't go in a straight line
The wood ramp made the back bounce forward from the dip in the floor of the ramp. If it was metal you may have truly sent it.
The speed n weight of the first car flattened those sandbags instantly, it wasn't a bump at all 😂
The way the rockets were stacked the thrust was not in line with the centre of gravity of the car meaning asymmetric thrust, they should have balanced it like the rocketman sledge they made and it would have flown better.
Exactly!
i think they still messed it up. on 2nd test car fell down due the extra weight in the front, they shouldn't have added it.
Feels like there overselling the experiment 😮
You weighed down the front, according to the myth, it wasn't, so this is a fail
waaaaay too much weight in the front... twice...
The front bumper was a terrible idea
Overwhelming 😮
If you are going to jump a car, why did they not use the Dukes of Hazard suspension jump? Watching the frame of the car dig into the ramp hurts. The ramp only needed to be 12" tall and made of something very solid. The landing on top needs to be long enough for the suspension to react at the speed you are going. The CG of the car needs to be back near the rockets, for the car to be stable in the air, but the car will be hard to steer when on the ground.
my self i had figured not much more than 500 feet because of the alingment of the rockets.
With that much thrust it would be impossible to keep going straight without some kind of active stabilization such as retro rockets. It was doomed to crash into the ground.
3 issues... first car...stupid hydraulic suspension with extreme negative camber, waaaaay too much weight up front. R/F wheel folds under, should have put the springs back in. Second car... waaaaaaaay to much weight on the front AGAIN! I called it when I saw that monstrosity! It opened up the ramp when all that mass hit it kicking UP the ass end when it hit that gaping hole the front made, dooming ANY distance whatsoever. It basically pointed the front towards the ground when it left ramp. The only thing that gave it ANY distance was the inertia gained from all that moving mass. Could have/should have done better...
The fact is that it’s just not possible. There’s a reason rockets aren’t shaped like cars. Even if they got the weight perfect to theoretically fly straight, it’d still be a fluke if it worked. The car hitting a fly would knock it off course, let alone a little wind. It can’t steer itself. Rockets steer themselves even when going straight.
we are not away for flying cars, but there are other ways to make a car to actually fly and to control it in air
I hope to dear God they didn't leave the Mojave desert looking like that!
The right front wheel was obviously hanging loose way before this test.
they use a curved ramp in a clip in the intro for something less powerful, but for some reason they insist on using banked ramps for these high powered rocket cars - smh
If the rocket-car run has ever been done, it would probably not have been done with a car with jacked-up rear springs. When the car's tail is pushed up the thrust of the rockets pushes down, at an angle that presses the front wheels more tightly against the ground, and the effect is the opposite of what was said in the myth.
I can't think of an experiment more dangerous than driving a passenger car at the take-off speed of an aircraft to see if it will take off, even in a desert and using remote control. So I wonder if the tail of the car was jacked up for the very purpose of preventing takeoff. With normal suspension settings and enough speed, the car would probably have started shaking from the turbulence so badly that it would have gone out of control. There could have been a catastrophic roll-over if one front wheel got momentarily lifted off the ground by the turbulence, while the other one retained its contact with the ground.
They had the wrong ramp. It should have been a curve ramp not a straight line.
The first car would have done better if it kept the right wheel on. Second car: grave mistake - too much weight in the front. Should not have mounted that heavy beam. The V8 was enough weight; perhaps too much. I envision that it would otherwise have kept a better attitude once airborne instead of tipping down.
Big mistake to add a weight to the front, im sure the "original" didnt do it, so the car would pottentialy fly up way more.
It could, but there would be a high likelihood of it just doing donuts in the air and no going farther
@@pengu1139 well yes, that would be one possibility but regardless of, if it would do donuts in the air, it would deffenetly fly way further.
@@Votexforxme look at normal rockets if they start spinning they do not go further some even stay in place untill it runs out of fuel, same concept, it would be pretty dope to see nonetheless
@@pengu1139 it doesnt matter the mass would still mainly go in one direction, physics is something easy to understand.
@@Votexforxmeexcept that physics is also just a wee bit too complicated to really understand. We have good estimates in general, but simulating every last bit that goes into this myth is probably a bit much.
Realistically the center of thrust was above the centre of mass. That was clear the moment the car went in the air as it nosed down.
Obviously starting the rockets too late, not enough time to hit full speed.
*"THIS IS ROCKET LEAGUE!"*
Wings would have helped. At least get that thing airborne and for a bit of distance
The second car was way too front-heavy, they need to do it again and balance the cars better
I thought it would be a bit cheaper to use a 360% camera with a headset
RIP Impala
What about using the original engine from the Chrysler Swish (which was an actual jet engine) which will run on any fuel that you want.
9:36 Didn't anyone ever tell not to step under a hydraulic boom?
What about mounting the rockets on the roof? I feel like it would be more stable pushing closer to the middle of the car and if the original adrenaline junkie did a bad job mounting the rockets,maybe the roof warped after ignition pointing the nose of the rockets down making the front end very light...I would think the weight of the car would be under the rockets like a pendulum and with proper balance it would fly quite a ways. Freak accidents are just that. A series of extremely rare circumstances that all collide at once to create a mind blowing event the world can't believe.
Center of thrust would be above the center of mass making it just tumble end over end
Fucking hell man that poor 67 Impala
I’ve always felt like the Asian guy was a spy
If you guys could keep it straight and get enough speed before hitting the bump… it very well could have gone
Jet engine is not a rocket engine. 😂
Myth Max 2: The Road Buster
Center of thrust was above the center of mass, so car nose-dived.
He can't steer to save his life .
We need a revision! It needs wings, better center of gravity, and it will fly
Then it wouldn't be a car would it, did you even watch the full video he said he didn't watch wings or stability cos that's cheating because then it isn't a car
@@Liam1992 so what? They are mythbusters, never stopped them from going beyond limits
@@lowe_sa2976 so you didn't watch it all then lmao
@@Liam1992 what is your point. Say it or concede defeat.
If a hose fails while the beds up that could get dicey.
rockets were strapped on wrong angle
