About the SR-71 breakup
What wasn't mentioned was that the pilot survived the SR-71 breakup but his 2nd seater didn't.
The SR-71 was being flown with an unusually rearward centre of gravity and suffered an engine "unstart" during a mach 3 turn. The was enough to make it uncontrollable, resulting in a hypersonic tunble and partial disintegration.
Neither occupant ejected. The pilot was thrown through the canopy with enough force to snap his safety harness and regained conciousness free falling in his inflated pressure suit before making a parachute landing. Something similar happened to the other guy except that his neck was broken as he was thrown out of the plane.
This episode doesn't probe anything about hypersonic bailouts or space-diving because of the way the occupants were slung out of a tumbling, disintegrating aircraft.
