A couple of years ago, its still pretty new and he could still hold the record for the only person to basically skydive from space. He was so high up it made Martian atmosphere look breathable.
Joe Kittinger did it in 1960. Meet Joe Kittinger, The First Man To Kiss The Sky by Jim Clash, Contributor Mar 23, 2017, 09:02am Meet Joe Kittinger, The First Man To Kiss The Sky Joe Kittinger’s Death-Defying Leap From the Edge of Space by Elizabeth Hanes October 05, 2012 Joe Kittinger’s Death-Defying Leap From the Edge of Space
That's so cool. Five miles high is the tallest mountain on earth, the island of Hawaii, while the tallest mountain in the solar system is Olympus Mons on Mars at 50 miles high. That mountain is so tall, if you didn't know it was there, you would never notice climbing it or when you reached the top, because the slop is that gradual. So tall, that it sticks out of the atmosphere of Mars. Joe skydived from roughly 15 miles high, which is still debatably within the earth's atmosphere. The Red Bull sponsored drop was 80 miles up in the stratosphere, which is bordering on the edge of space, with the latest estimates being that our atmosphere is not quite as thick as we've assumed at around a 100 miles up. Past that, the air is so thin its ridiculous to call it air anymore.
The altitude for Kittinger in 1960 was about 19.3 miles (102,800 ft). The altitude for Baumgartner in 2012 was about 24.2 mi (127,572 ft). Sufficient atmosphere is present at that altitude to use a balloon as the launch vehicle.
Yeah, even the newer spy planes have limited altitudes and you would need a scramjet to go higher, but they are all classified and only flown at night, with the exception of NASA's experimental model. I would guess it will be someone like Virgin airlines that might pull off the next extreme high altitude skydive, and it would probably require a small capsule that can be ejected. Those jets fly so fast that the flame likes to ignite about fifteen feet behind the engine, and I don't know how slow they can fly in that thin air. The skin of these aircraft gets so hot, instead of aluminum they make them out of titanium and ejecting even someone in a spacesuit at those speeds would be insane. They would require some sort of shielding that allowed them to slow down first, with ablative shielding being possibly the best option, which would burn up before it hit the earth. The skydiver could eject out the back, use the shielding to slow down, then discard it and free fall.
