Scott Kelly responds saying he went on a space walk from the ISS at mach 25. The gardener is technically right that mach numbers don't really apply in a near vacuum. It's also kind of off topic because we know the Darkstar is in the atmosphere and not in space, and therefore there is no "re-entry". But Scott is right that the real issue would be heat and not getting splattered. I also want to point out that we don't actually see Maverick eject, and it's likely that he would have been ejected in a capsule (like in several real aircraft like the B-58) rather than just thrown out of the plane in his pressure suit as Scott suggests. permalink fedilink source parent
