I guess technically, but Kelly is talking about an aircraft which implies the craft is still in atmosphere and therefore Mach can still be calculated.
The original thread was started by Neil deGrasse Tyson saying that Maverick would be "splattered" during ejection at mach 10. 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.
Yes, but the gardener guy is specifically talking about the ISS flying in a vacuum. So he is not wrong. I find the comment of that Bruno dude just condescending.
Just because an aircraft is capable of mach 10 in atmosphere doesn't mean that you would call that speed "mach 10" everywhere. Gardener is arguing semantics at best.
