The first one about farts does not seem probable...sky divers today don’t seem to have this problem, and how many paratroopers were dropping from 20k feet anyway?

Sky divers rarely go above about 15,000 feet. An unpressurized airplane cannot carry passengers above that, without providing supplemental oxygen.

But, this most likely applies to bomber crews. They would fly as high as possible, in an attempt to stay out of the range of flak.

If this were meant to apply to bomber crews, why wouldn’t the post refer to them as Airmen? instead of Soldiers?
