The need for full-motion control surfaces was discovered around the time — or soon after — the crash of the de Havilland DH 108 "Swallow" that killed Geoffrey de Havilland in England.
The need for full-motion control surfaces was classified top secret, and was one reason films like this one were not released to the public for many years after the event.
If the F-86 was taken supersonic, it would have been very risky to the pilot. I'm not saying it didn't happen; actually, the sound barrier had been closely approached if not broken by pilots of the P-38 Lightning, when in steep dives, during and immediately after WWII.
This is true of the F-86 models before the -E variant.
It was Yeager who, during flights in the X-1 that found that changing the angle of incidence of the entire horizontal stab (all-flying tail) allowed the aircraft to he controllable in pitch.
All models of the F-86E and beyond used all-flying tails.
My dad flew 86s
I shoulda asked him
He flew 100s and the crazy 104 as well....
