[Servant of the Nine]

He won't be the first. A US Airforce Officer/researcher parachuted from a baloon at a similar height and went supersonic during the 1950s.

[Cold Heat]

Yeah, that rings a bell. Seems I read something about it many years ago.

Yikes. The highest altitude I ever jumped from was 13,000 feet, AGL, from a Beechcraft Queen Air. The O2 was a little thin up there, the sun was setting, and it was getting COLD. This was in Utah, where the elevation of the drop zone was 5,000 ft. No wonder I got to feeling a little light-headed before we jumped.
