Bailout at 43,000

I haven't seen this film since 1957, and have been looking for it ever since. As there is no other information posted, I will report from memory (I was 11 years old at last viewing). This is a story about Air Force researchers trying to develop a safe ejection system for the new B-47 bomber. The navigator position required a rather unique ejection out the bottom of the aircraft. Added to this were the new human physiology problems of a man leaving a pressurized aircraft at extremely high altitude.

That's all I can remember. I've long thought it would be an interesting account of the development of new flight technology. John Payne was nearing the end of his film career at this time and about to go into television with "The Restless Gun," so this was probably a fairly low budget movie. The Air Force of course cooperated fully in movies like this in the interest of a larger share of the defense budget, so everything shown in the film is real, no cheesy miniature effects.
