F-15 Eagle Spatial (Spacial) Disorientation: World Record G

The next short clip shows the cockpit/HUD view From an F-15 that the pilot became spatially disoriented. If I remember correctly it was broad daylight in clear visibility, a mitigating factor is the color of the sky and seas that day were very similar.




The fact the F-15 held together and was able to land safely is a testament of its durability. I can't remember exactly but it sustained like 15-20 Gs for about 2-3 seconds. For a fraction of a second it pulled something like 30-40 Gs. It held together but the wing skin had crinkled (technical term j/k) because the airframe was bent so badly. Unfortunately I have no external views. It pulled so many Gs that the tape pulled off the recorder head and lost sync for a bit, so the tape misses the highest G.

I think this might be the worlds record for the most Gs a manned airplane has pulled and landed safely.

As far as I know it was the most Gs a piloted aircraft ever pulled and was able to return safely (though the plane was badly damaged).

By riding the decelerator sled himself, Dr. John Paul Stapp demonstrated that a human can withstand at least 45 G's in the forward position, with adequate harness

46G "Sonic Wind" sled ride

Skydivers have survived after falling without a parachute or a failed parachute (streamer). The impact with the ground would probably be in the neighborhood of 100-200 Gs

I talked to someone who knows the guy and heard the story first hand. The guys name was Barney Shaw and he pulled 12.3gs on the recovery. At 15Gs, the wings would've come off.

Piloti337: If your claims are true about Barney Shaw then thank you. Understand why I am skeptical of some self-proclaimed expert like yourself that has repeatedly stuck your foot in your mouth. I think 12.3 G on the official textbook record is plausible. However I still suspect it is a lowball figure. That sounds more like the short but sustained value, it may not even be the peak sustained value, let alone the instantaneous peak.

[ATFSCrash]

Piloti337: Do you know what the G frame rate of the flight recorder of this particular F-15 is? Some of the flight recorders I have looked at have are very slow such as 1 fps; thusly the peak sustained G that is recorded could be slightly low and the peak instantaneous G could be entirely missed. I suspect my question has just elevated your level of understanding and have humbled your ignorant criticisms of me. However since the typical troll has no honor I expect no apology.

the 30-40G measure is instant G's that the plane may suffer, though it's not sustained. It's like the cheap electronic sound systems that say to support 2000Watts. I mean! an amazing $300dollar sound systems can barely produce 50watt in total (and that is LOUD), and the cheap chinese systems claim to produce 2000Watt or more but in PEAKs, not sustained RMS.

I think it's the same case for the airplane.

I was assigned to the 33TFW QA at the time. This was our F-15C which was deployed to south Florida. It was a new F-15, under 150 airframe hours. The G meter read about 12.6G, but the OWS (Overload Warning System)registered numbers in the mid to high teens on various areas of the airframe. Back in '77 or '78 (before OWS) when I was with the 1st TFW, a F-15A pulled and estimated 16G's. The wings were warped, though not visibly. But when measured it was very evident. The wings were replaced.

@ATFSCrash its funny, an air force mechanic has been telling me this story before i ever saw it on the web so i know your telling the truth.

Piloti337: Like a typical troll, flamer, con, bigot; you have taken my words out of context and attacked me. That is not my fault, it is yours, you only have yourself to blame. You need to learn to work on your reading comprehension and to be less prejudice. It seems you could use some anger management discipline/training as well.

[ATFSCrash]

Piloti337: This is real life; not Hollyweird or one of your arcade video games. Wings do not snap off at an exact given one dimensional value. As I said and as engineers say: it depends on the variables. Loadout; weight, airframe life, construction variations (IE longerons), loadout and configuration, temperature, etc. often there is damage or de-formation before a total catastrophic failure. Some of your comments and claims are absurd.

[ATFSCrash]

Piloti337: You need to learn the difference between instantaneous and sustained G. As I said my figures were estimates/speculation/guesses. Whereas you have used harder language and hard figures which you have repeatedly retracted after being confronted with the facts and continuing your education. The more of an education that you get the more that youll find that youre hypocritically jumping to conclusions and making a fool of yourself.
