Would that be considered boiling? I always thougt there was a different word for state changes when it's caused by pressure rather than temperature
It's always boiling when a liquid becomes a gas, different pressures just mean different temperatures are required as the boiling point changes. You may be thinking of sublimation when a solid becomes a gas without liquefying in between?
The odd thing is the speed of sound is slower the lower the pressure, so he well surpassed the speed of sound for the local air pressure.
I also thought it was cool that the only person he wanted on the radio was the previous height record holder who was an advisor on the project.

A ship has more mass behind it; It's comparable to how a rock falls faster than a feather. A person can't reach the speeds (in freefall, at least) that would create enough friction to make that much heat
Mass has nothing to do with it, air resistance is a big factor (as otherwise a rock and a feather fall at the same rate), but it's mainly due to entry velocity. He started within the atmosphere with very little velocity, whereas a ship already has considerable velocity when it hits the atmosphere.
