Given the physiological limitations of the human body, when I first read this story and everyone was screaming about security, I was thinking how did he survive? I've done some skydives from 30,000 feet, obviously with full O2 mask, warm clothing, etc. And been to a few chamber ride classes. Whole security thing we can argue for eternity but comment of, "frigid temperatures cause a state of hypothermia, which preserves the nervous system." Now that's interesting.
I never would ever consider riding in a wheel well, first danger is those doors first lower prior to wheel retraction (if on one of those, drop you go). Then when wheel folds up, would know where to place yourself without getting crushed?
I remember in a magazine back in early 1970s or a long time ago, someone got a photo of a person falling from a airliner on takeoff. Apparently photog took a picture of an airliner taking off and happen to catch unlucky "hitchhiker" who fell from the wheel well.
