Except this was done in a very densely populated area (according to the Swedish commentators in the video, it was around half a million spectators) and you can clearly see the buildings of Stockholm. I don't know the details, but by the looks of it, the pilot atleast tried to steer the aircraft towards the small hill before ejecting. If the airplane crashed on a building it could be a disaster and that pilot, who is a test pilot btw, knows this. But in EVERY other circumstance I totally agree with you. Don't try to save the aircraft, your life is always worth more than a broken aircraft. And even if we speak monetary wise, you as a pilot are still worth more than a single aircraft as experienced and skilled pilots do not grow on trees nor can be manufactured.
@@AtroFear I don't believe for one second that he tried to steer it away from the crowd. I was there and saw it from a different angle, and the nose was practically straight up when he ejected. It's the same pilot who crashed the first plane when landing (amazing that he survived that one), so he might have just panicked...
I was there, standing on the middle of Västerbron. It's a miracle that nobody died, there were lots of people everywhere, except where the plane crashed.
@@jonathanbank3130 same here to my girlfriend at the time hehe.-. had to run down to the water.. even took alot of pics but when i was gonna get them they said "all the pics was black" suuuure they probably sold them =)
The reason for the crash was that the pilot flew into its own turbulence. When the pilot tried to correct, he basically overloaded the flight computer. The Gripen as many other recent aircrafts is inherently unstable. A low level control loop stabilizes the aircraft, while a high level control loop interprets the commands from the stick. SAAB knew already that extreme movements of the stick would starve the low level control loop of processing power, but they could not see any reasons why a pilot would do this, so the pilot was not informed of this "unlikely" problem. When entering the turbulence, the pilot corrected as he would have done with previous fighters, so only the high level control loop was serviced, and the plane lost all stability. Then the engine flamed out, so there was nothing more to do than to eject. If the pilot had instead let go of the stick, the low level control loop would have made the needed correction, and the problem would have disappeared. After the crash, the flight computer S/W was changed to make sure that this problem disappeared.
APRichelieu Same shit as on MS Winshit... an application can use all the memory and processing power and deprive the system from ressources making it frequently freeze as soon as a particular application overflows... Why can't all these genii devote minimal ressources to critical systems? It seems so obvious to me...
The engine shouldn't flame out during high AOA and back slide. I don't know what Volvo's modifications applied on General Electric 404's engine. F-16 VISTA has General Electric F110 engine which can handle very high AoA, back slide and post-stall.
The engine flamed out because of the ejection seat rocket exhaust blew right into one of the engine air intakes when the pilot ejected. There is another video where this is seen more clearly, but you can also see in this video, if you pause and try to watch frame-by-frame - the engine flameout happens a few frames after you see the first smoke puff of the seat ejection.
For Gripen www.flightglobal.com/news/articles/saab-performs-gripen-high-alpha-trials-12697/ _Tests so far have been carried out at steady-state angles of attack of up to 28 degrees._
The steering system malfunctioned on both of he's flights and that was the reason for he's 2 crashes, he is a testpilot and gets to fly the early prototypes that is not sorted out yet so i dont think he has a very simple job, and no, he is no way near to be a noob.
Not likely. The plane /after the ejection/ behaved exactly as the "relaxed stick stability" predicts for slightly tail-heavy configuration. So neither the software nor hardware but only a pilot command seems to have caused the crash of the fully operational and functional plane. But I am not blaming a fighter/airshow pilot for trying something untried.
@Erik Mellander Read www.sciencedirect.com/science/article/pii/S1474667015332274/pdf?md5=89008a7c3fa4a6978d9460bba43737d2&pid=1-s2.0-S1474667015332274-main.pdf I quote from the PDF *The JAS 39 Gripen is a 26 degree angle of attack aircraft for the light external store configurations* and 20 degrees for the most heavy external store configurations. The variation of angle of attack with roll stick position is used to give roll command priority, when the pilot demands roll rate.
But the investigation made told that the planes computer had an error that made it possible to do stick manouvers that the actual aircraft could'nt handle. No matter what you say it was a malfunctioned system. Or did you do the actual crash reports? Much experts on here.
I have to say the Swedes know how to build Fighter jets as well as cars! The Draken was a thing of beauty! The Viggen was a big and tough brute! and the Gripen incorporates both! :D
@@DrLoverLover what do you mean crashes all the time??? yes of course several planes has crashed, the most infamous one was J29, but we have not lost more planes than the americans and russians and brits. Especially the Americans, their planes, with the exception of the Fenomenal F16, are just overhyped and patrioticed crap.
It wasn't the pilot's fault. The crash was caused by an comupter error, that gave him no control of the airplane and no other option but to eject. The pilot, Lars Rådeström should not be hold response for the crash.

I think they later concluded that he basically could have given the engine full throttle but as this issue wasn’t know before he couldn’t have known that and with the limited time he had on his hands he couldn’t really start to experiment with finding solution.
SWEmanque No couldn't have given it full power. See the flame from the engine. The unintended "Cobra" gave the engine compressor stall. And he still had Fligth control issues. Given his height he made the rigth call. That he shouldn't have give an airshow over an populated area is another thing.
yea dude, this was the same pilot who was involved in first Saab Gripen prototype crash in Fed 1989. So obviously he didn't want to take any chances with his life for second time. He got out as soon as he could.
I was there in 1993, my first and only time I'm Sweden. I was on Långholmen Island, probably less than 1/2 km from the crash site. We had to walk past it to get back to the car. The airshow continued, but most people were bummed out and just went home. Island
JAS 39A Gripen (serial number 39-102) crash on Longholmen on 8 August 1993 the crash was once again the result of pilot-induced oscillation (PIO)....After this crash L.Rådeström decided to retire as a test pilot at the age of 49. The usual retirement age of test pilots is 50, but in an interview he said that he "did not want to push his luck for just another year."
Both this crash 1989 and the crash 1993 where due to the bad programming of the FCS . It was later reprogrammed and the problem has not accured since. It was like driving o car on ice, over steer and you will have a backlash and then you will over steer again, ending in the ditch.
he blew up a 25 million dollar plus jet. Fire him......of course he could have stayed in motor pool for one year ...but article is 3 years old. let him keep his retirement....but flying NO....the question is ....where did this airplane land after ejection....and what damage did it do with the tanks full of aviation fuel......that exploded.
It's actually quite funny, this was the second Jas 39 Gripen that Lars Rådeström crashed. He was the most accomplished test pilot in Sweden, and you can not really put the blame at his feet for either incident.
I will admit it is nice to see this accident from different angles. I don't mean that in a bad way, but you are now able to see different angles of how it lost control and came down. I will admit it is funny when the crowd cheered thinking it was doing a "cobra!" maneuver.
when it were a big fighterpilot exercise in the U.S. last gear swedish pilot were there with 7 JAS 39 Gripen, they won every contest and battle. And it were aircrafts and contries from all over the world there. how the hell can you say that the Jas 39 gripen is bad. this film is from the 90s, the Gripen is much better now and one of the most greatest plan in the world
@@lemboisimsonni2272 A mixture of both. He was not allowed to participate in another test flight of the gripen, and at the same time, he didn’t want to in fear of it happening again.
I think I read somewhere that if a pilot uses the catapult chair twice, you are no longer allowed to be a jet fighter pilot because of the damages to the spine that happens when you catapults yourself. Someone is more than welcome to correct me.
Depends on how you look at it. This was, just like in 1989, a pilot-induced oscillation. Rådeström pushed the control stick to it's near limits very fast, which left the control system saturated. It couldn't move the control surfaces fast enough to comply. By the time they caught up, we was already pulling the stick in the other direction. So in effect, had the computer flown alone, it would have made it. Had the pilot had manual controls, he would have made it. But the two together...
Living on the Edge... And the system that he so hard tried to fuck up. Probably saved his life. Twice. No judgement - life lessons (as a test pilot who is not Chuck...) Well he crashed also.
Jag stod mitt på Västerbron med kompisar. Tanten bredvid mig säger till sina barnbarn när Rådströms fallskärm vecklas ut ”Titta barn dom släpper ut ballonger”. Alla springer därifrån, jag och mina kompisar springer till kraschplatsen. Kanske inte jättesmart så här i efterhand. Vraket var utbrunnet när vi kom fram och det var bara ett skelett kvar.
It's amazing that this crash didn't killed Gripen project. Considering the time, USSR no longer exist, relationship with Russia was on upward turn, Swedish politicians could just shut this project off and purchase some 50 F-16 as replacement of old jet.
This was crazy tho, for those who don't know what happened was that the fly by wire system failed and the pilot lost control, as you can see he does a cobra like maneuver and loses control.
It's well below the ejecting hight and what you don't see on this video is that it's very close to a 4 way lane bridge w. 20000 spectators. The plane crashed about 100 feet from those people. One women was badly burned, no one died. From then on, no airplane shows was allowed ever in Stockholm city.
Bnox.pk, the same reason caused the first prototype to crash upon landing in Feb 1989 and was flown by the same pilot who was flying this Saab in this video.
It is a light weight fighter .It does not need that engine as the current engine provides enough thrust to travel twice the speed of sound.

Exactly! Kind of fascinating, I've flown Gripen simulators and it's impossible to replicate this, I tried! The problem was fixed .... Sadly. You can't get anywhere near that alpha anymore :(
Stay up in the air? The Gripen has had 8 accidents during it's active service, of which none were fatal. If you want to I can find quite alot more videos of your F-18's slamming to the ground then the Gripen.
Min moster var där med sin kompis men en röst sa något och någon osynlig tog tag i henne och sa åt henne att söka skydd och att springa iväg fort. Då sa hon det till sin kompis att vi måste springa planet kommer att krascha. Så de springer så fort därifrån och när dem står på en säker plats kraschar planet och delar av planet landar exakt där dem stod och det var ett par bredvid som blev väldigt skadade.
If he had put on full gas, I think he could have rescued the aircraift and flying back to the base. Yes there was a "glitch" but he was a test pilot and they must be always very clever in every situation
Considering their was a flameout at the same moment he ejected, he would had no time to recover at that altitude. The pilot wasen't at faulth since this crash and the crash before was due to errors in flight controls software.
The flameout you can see when he bails out was because of the rocket blast from the ejection seat, the engine air intakes are right beside the cockpit. On the other hand, it looks like the plane was completely stalled at that point, so it's doubtful that he could have gained enough airspeed again before hitting the ground.

@hitmannor1983 I hope you're joking right now, the Spitfire is both slower, less armored, less weaponry. The JAS 39 Gripen is among the most agile aircraft in the world and could quite easily shoot down an F-18.

Poland, Norway and Belgium has selected F-35A over losers in Finland Flag 2012.
I read elsewhere that it was a failure of the fly by wire system. That system should automatically negate PIO and make it impossible unless switched off. If all aspects of the system fail, the plane will do just what you saw here; fall out of the sky.
I think he could have saved the aircraft. If he had waited a few seconds he could have stabilazed it an go into a landing. But today JAS Gripen is the safest aircraft and maybe the best for the money in all the world
"Fly by wire" the pilot moves the stick and the COMPUTER moves the control surface, those computers rely on sensors all over the airplane to make the maneuver the pilot wants while maintaining control of the airplane. If the sensors or the computer fail the plane literally stops flying. ALL MODERN JETS have fly by wire.
I think it was cause the pilot had no control of the aircraft as there was a severe malfunction of the flight control system. I know that a lot of pilots stay with the aircraft until the last moment to avoid civilian casualties but I think in this instance there was really nothing he could to do avoid this. And since he had no control of the aircraft, he ejected to avoid being trapped in the aircraft as it came down. Well that's what I believe anyway.
@hitmannor1983 What makes this jet bad? It's high tech, good manoverability and great weapon system.. The US, considered having the best AF in the world, have F-18 as their main jet fighter. Tech and weapon system wise their both very similar. But in the air F-18 is as manoverable as a fridge against GRIPen.
kovy.free.fr/temp/rafale/pdf/12332.pdf Swiss damning report against Gripen C vs Swiss F/A-18C From Swiss, _The Gripen has been assessed unsatisfactory for this type of mission. The main weak points of the Gripen were insufficient Range/Combat Radius and its aircraft performance_.
thediplomat.com/2020/04/flankers-vs-gripens-what-happened-at-the-falcon-strike-2015-exercise/ The Su-27 on the other hand, benefits from greater engine thrust and better sustained kinematic performance/turn rate than Gripen-C. SU-27SK has a superior sustain turn when compared to Gripen C. From China's SU-27SK vs Thailand's Gripen C, the low wing loading argument means little when Gripen C's engine is weak.
Pilot induced oscillation i believe was the cause, very common problem if you aren't careful with fly by wire control systems. Also if you look on current Gripen's they have tiny-tiny wings behind but higher then the stabilizer on each side to give better control at certain attack angles.
The aircraft had a big software flaw. Think of if like windows vista and so the aircraft failed to filter his reactions and so did overdo the manouver. And Stalled you can see the engine not getting any air so it pumped it self to death.
thanks for the note Melancholy,but if positively was not a pilot mistake this accident was an even worst fact for Gripen because that flight was not an "extreme flight envelope check" ,but an exhibition with a production aircraft . I guess Saab engineers have wisely resolved "teething problems" of Gripen. :)
Looking for a different angle I think he lost too much of airspeed the plane became instable. Just see the wings turning, then stalls. It is like he pulls then far too much and it looks like the engine also stalls just before the ejection. You can see a flameout from the nozzle. Just guessing.
He didnt attempt to do a cobra, the flightsystem was spazzin out, this plane was in development. And since it did a cobra so low with basically no speed, there is no way to get the plane back after that.
it wasn't his fault and I also happen to know he didn't lose his job. friend of my father who also were in the airforce. Lars was mostly pissed off by the whole event because his mother in law was there watching. typical.
Jag var i Kungsan och hörde planen åka fram o till baka när någon sa att ett plan har kraschat på söder... vilken tur att den landade där den landade...
What a fighting aircraft looks like out of control.. kind of looks like a wild horse trying to buck of the rider.. it worked but the horse/plane died :/
Well, that depends how you look at it really. Could an ace pilot in a spitfire take down an F-18 Rookie? No, because the aircraft is at fault here. The F-18 has both superior electronics and all-out better weaponry system. The Spitfire has nothing of that, most readings are hydraulic, no lock-on warnings and no flares. It's screwed. I stand my ground though, the JAS 39 is more manouverable due to it's delta wing buildup and it has more Thrust to weight then the F-18.
Delayed ejection has killed many pilots. This guy ended the day breathing.
Airframes are replaceable, human lives are not.

It's amazing that this crash didn't killed Gripen project.
Considering the time, USSR no longer exist, relationship with Russia was on upward turn, Swedish politicians could just shut this project off and purchase some 50 F-16 as replacement of old jet.
From disaster to success
20 år sedan? Jisses, nu känner jag mig gammal! =)
Å den kommentaren var också sju år sen... tiden går snabbt!
Vad händer?! Hur kan jag vara över 40 nu?! :O
Jag da
This was crazy tho, for those who don't know what happened was that the fly by wire system failed and the pilot lost control, as you can see he does a cobra like maneuver and loses control.
Haha the guy in the end is like "wtf stop interviewing me!"
93. Jag var där, framför stadshuset och såg hela spektaklet.
It's well below the ejecting hight and what you don't see on this video is that it's very close to a 4 way lane bridge w. 20000 spectators. The plane crashed about 100 feet from those people. One women was badly burned, no one died. From then on, no airplane shows was allowed ever in Stockholm city.
Didn’t know David beckham read the news in sweden
Foi problema de software do flight envelope. Pelo menos o software da cadeira ejetável funcionou direitinho.
Acerto mizeravi
wow gripen did a nice cobra with fly by wire or electrical command shut down... really impressed. however ikea has a good After-sales service.
Jag var nio år och stod i publiken (minns inte var) och när piloten sköt ut sig trodde jac för några sekunder att det var en del av showen.
I thought it was a part of the show. It looked Epic, so long as the plane isnt dumped into people.
I don’t think Gripens are meant to cobra
He tried to become Su-27 flanker but ended up ejecting from the jet.
Gripen needs to have Super Hornet's engine inlet design and GE-F414 engine upgrade for high AoA.
i think it was flight computer problem that lead to this crash .
Bnox.pk, the same reason caused the first prototype to crash upon landing in Feb 1989 and was flown by the same pilot who was flying this Saab in this video.
It is a light weight fighter .It does not need that engine as the current engine provides enough thrust to travel twice the speed of sound.
Exactly! Kind of fascinating, I've flown Gripen simulators and it's impossible to replicate this, I tried! The problem was fixed .... Sadly. You can't get anywhere near that alpha anymore :(
In the 60s and 70s we had 1500 airplanes ready to fight. Also on Roadbases. Airfields on roads. Nice . In the 60s and 70s .
Starts to oscillate.
Tries to pullout of it.
Suddenly 180 degree flip.
Pilot: "Fuck this I'm out"
27duuude 90 degree
Stay up in the air? The Gripen has had 8 accidents during it's active service, of which none were fatal. If you want to I can find quite alot more videos of your F-18's slamming to the ground then the Gripen.
Gripen introduced 13 years later. 2000 F-18 produced compared to ~300 gripen.
this was under the development of jas in the beggining of the 90s
O gripen caiu algumas vezes o fa/18 e su30 cai varias vezes todo tipo de caça cai filho é falha no sistema
The Gripen had small problems during its early days. Those are gone.
I remember this. Of course he survived, you can easely see that he ejected from the plane
George the guy yeah true. it would be dumb if he didnt
@@waduhek8931 There are the people that dont survive ejections actually. They are subjected to tremendous forced when ejected so yeah.
@@AceYoPro yeah ik that, but much higher chance than getting fucked in the airplane
i'm no expert, but to me it seems more like a stall with rolling wings after the pilot ejected than controlable aircraft as suggested
Pilot Induced Oscillation. He used too much force on the control column.
Ahhh, yes. Software. Oh, you like flying? Well, this zero just turned into a one and now your jet is a smouldering wreck.
Yeah, because that's how that works 😂😂
Min moster var där med sin kompis men en röst sa något och någon osynlig tog tag i henne och sa åt henne att söka skydd och att springa iväg fort. Då sa hon det till sin kompis att vi måste springa planet kommer att krascha. Så de springer så fort därifrån och när dem står på en säker plats kraschar planet och delar av planet landar exakt där dem stod och det var ett par bredvid som blev väldigt skadade.
Det där ör bara en fucking lögn det blev rapporterat att ingen skadades svårt
If he had put on full gas, I think he could have rescued the aircraift and flying back to the base. Yes there was a "glitch" but he was a test pilot and they must be always very clever in every situation
Lars-Göran Andersson gne it's more a fly by wire shutdown or electrical command shut down... so nothing to do except eject...
Softvaran var inte klar. Det var orsaken till kraschen.
Considering their was a flameout at the same moment he ejected, he would had no time to recover at that altitude. The pilot wasen't at faulth since this crash and the crash before was due to errors in flight controls software.
The flameout you can see when he bails out was because of the rocket blast from the ejection seat, the engine air intakes are right beside the cockpit. On the other hand, it looks like the plane was completely stalled at that point, so it's doubtful that he could have gained enough airspeed again before hitting the ground.
yeah should have gone straight up like in dogfight
Um piloto da FAB (Força Aérea Brasileira) jamais faria uma barbeiragem desta, vejam o exemplo da Esquadrilha da Fumaça, que o Piloto salvou a eronave no braço, Bravo FABIANO, BRASIL!
Pilot: Stupid airplane, why don't they get me one that works properly?
Great camera...
Simon R this was 20 years ago
Jag stod faktiskt nere på berget, och hörde både explisonen och kände brand röken.. De var verkligen märkligt!! Jag tror bara vara 12 år då.. Men minns väldigt tydligt. På den tiden hade man filmkamera bara ingen iphone =S..
We are a small nation. can.t compete with US , Russia UK , or France but we have made a lot of great Airplanes !
@hitmannor1983 I hope you're joking right now, the Spitfire is both slower, less armored, less weaponry. The JAS 39 Gripen is among the most agile aircraft in the world and could quite easily shoot down an F-18.
Wrong,

_Overall, flying the F-35 reminds me a bit of flying the F/A-18 Hornet, but with an important difference: It has been fitted with a turbo_

Swiss damning report against Gripen C vs Swiss F/A-18C.
I read elsewhere that it was a failure of the fly by wire system. That system should automatically negate PIO and make it impossible unless switched off.
If all aspects of the system fail, the plane will do just what you saw here; fall out of the sky.
I think he could have saved the aircraft. If he had waited a few seconds he could have stabilazed it an go into a landing. But today JAS Gripen is the safest aircraft and maybe the best for the money in all the world
För lite luft under vingarna så någon marginal att vänta fanns inte.
"Fly by wire" the pilot moves the stick and the COMPUTER moves the control surface, those computers rely on sensors all over the airplane to make the maneuver the pilot wants while maintaining control of the airplane. If the sensors or the computer fail the plane literally stops flying. ALL MODERN JETS have fly by wire.
I think it was cause the pilot had no control of the aircraft as there was a severe malfunction of the flight control system. I know that a lot of pilots stay with the aircraft until the last moment to avoid civilian casualties but I think in this instance there was really nothing he could to do avoid this. And since he had no control of the aircraft, he ejected to avoid being trapped in the aircraft as it came down. Well that's what I believe anyway.
@hitmannor1983 What makes this jet bad? It's high tech, good manoverability and great weapon system.. The US, considered having the best AF in the world, have F-18 as their main jet fighter. Tech and weapon system wise their both very similar.
But in the air F-18 is as manoverable as a fridge against GRIPen.

Swiss damning report against Gripen C vs Swiss F/A-18C
From Swiss,
_The Gripen has been assessed unsatisfactory for this type of mission. The main weak points of the Gripen were insufficient Range/Combat Radius and its aircraft performance_.
thediplomat.com/2020/04/flankers-vs-gripens-what-happened-at-the-falcon-strike-2015-exercise/
The Su-27 on the other hand, benefits from greater engine thrust and better sustained kinematic performance/turn rate than Gripen-C.
SU-27SK has a superior sustain turn when compared to Gripen C. From China's SU-27SK vs Thailand's Gripen C, the low wing loading argument means little when Gripen C's engine is weak.
Pilot induced oscillation i believe was the cause, very common problem if you aren't careful with fly by wire control systems.
Also if you look on current Gripen's they have tiny-tiny wings behind but higher then the stabilizer on each side to give better control at certain attack angles.
The aircraft had a big software flaw. Think of if like windows vista and so the aircraft failed to filter his reactions and so did overdo the manouver. And Stalled you can see the engine not getting any air so it pumped it self to death.
...DAMN! what the hell happened?...
That seemed a very strange stall - he was flying horizontally...
...had he some malfunction?
why did the pilot eject so fast ?
I visit the monument in Stockolm. Lost of time. See VASA museum and go.................
2:29 The flight computer stabilizes the plane as soon as the pilot let go of the stick.
No. It would of have pancaked eaither or if hte pilot was still in the cockpit or not. Lost of thrust.
de e inte sant... man.. man tror inte.. (ehh vafan ska jag stå här för)
skum snubbe i slutet :D
thanks for the note Melancholy,but if positively was not a pilot mistake this accident was an even worst fact for Gripen because that flight was not an "extreme flight envelope check" ,but an exhibition with a production aircraft . I guess Saab engineers have wisely resolved "teething problems" of Gripen. :)
Looking for a different angle I think he lost too much of airspeed the plane became instable. Just see the wings turning, then stalls. It is like he pulls then far too much and it looks like the engine also stalls just before the ejection. You can see a flameout from the nozzle. Just guessing.
@@tamasgutpinter342 What I know the fault was in the computer.
How do you crash this thing twice and live?
Crash from about 2:15 and on.
My father was standing in the bridge watching
Infact, nobody got serious injuries. That's pretty cool.
Except the pilot.
@@dennislindqvist8443 the pilot? He survived.
I thought he ejected too quickly.. or maybe he knew very quickly something was terribly wrong during that attempted cobra.
He didnt attempt to do a cobra, the flightsystem was spazzin out, this plane was in development. And since it did a cobra so low with basically no speed, there is no way to get the plane back after that.
it wasn't his fault and I also happen to know he didn't lose his job. friend of my father who also were in the airforce. Lars was mostly pissed off by the whole event because his mother in law was there watching. typical.
Herregud, finns det nån youtube video utan dina kommentarer?
@@MarcusN-kp1jn Det skulle jag tro 🤔
the "steering" was after a few seconds... when they begin whit the "fiber" steering every plane had that problem.
This was the bird strike crash
I wonder what flight computer they used, pentium 386 whit windows 3.11 dos.?
Most likely radiation-hardened PowerPC.
It was a bang and fire suddenly.🥺
Tragic.
Not the plane shoot down.... it is the pilot.
Слава Богу, пилот жив.
Vejam o que é capaz um Bom Piloto Fabiano da Esquadrilha da Fumaça em "Domingo Aéreo 2009 - AFA - Manobra Perigosa!" no yuo tube.
Jag var i Kungsan och hörde planen åka fram o till baka när någon sa att ett plan har kraschat på söder... vilken tur att den landade där den landade...
Thats a gnarly stall
he dident stall, there was a glitch in the computer that made him loose control
What a fighting aircraft looks like out of control.. kind of looks like a wild horse trying to buck of the rider.. it worked but the horse/plane died :/
Lmao , fly by wire failed for an unstable aircraft.
Can any one explain to me how that happened? Did the fly-by-wire computer break?
Funny screams at 02:23
You could tell its what happened. That shit's liable to kill a pilot one day. He must of pulled 9 g's instantly.
Yes, if it can stay up in the air.
They've been coming since august 8th, 1993, when this happened.
How fortunate for the people that it did not crash in a built up area with lots of people. It could have killed many people.
příčina nehody.jednoduchá pilot letěl nišší rychlostí než je pro přistání a letoun se mu propadl
1st question....did it hurt anyone?
alvin richover 1 Hurt and no deaths. It was a planefaulty that make this crash.
Please give me the total cost on that.
*****
No. just 4,4 million.
Not including the aircraft itself.
That is some 40 million.
@hitmannor1983 Yep a piston engine propeller airplane with a 7.7mm machinegun is better then a jet engine airplane....

oh shit what a spin
Well, that depends how you look at it really.
Could an ace pilot in a spitfire take down an F-18 Rookie? No, because the aircraft is at fault here. The F-18 has both superior electronics and all-out better weaponry system. The Spitfire has nothing of that, most readings are hydraulic, no lock-on warnings and no flares. It's screwed.
I stand my ground though, the JAS 39 is more manouverable due to it's delta wing buildup and it has more Thrust to weight then the F-18.
