There's been a number of successful supersonic ejections of military pilots over the years. It's extremely dangerous and very likely to fail, but it's better than the alternative. The basic idea is a drogue chute stabilizes and slows the pilot.
Whether the same idea could be adapted to a whole plane I don't know, but I would be skeptical of just on the basis that you probably wouldn't trigger such a thing unless the plane has had a substantial failure such that it could overpower any drogue chute.
Lol! I up-voted you (seriously, I did) because this is close to the platonic ideal of a HN comment: egregious pedantry, plus a nerd-flex.
For those out of the loop on the nerd-flex, "Habu" was an unofficial, insidery nickname for the SR-71. It's the name of a venomous snake from somewhere with an SR-71 base (was it Okinawa? I think it was Okinawa), that the locals applied to the plane, because it (like the snake) was black and dangerous-looking.
i'd be willing to believe it's an economics thing more-so than a physics thing.
one could envisage a '747-like' sized plane with many passenger escape-pods similar to the pod from an B-58 Hustler -- but who would pay the astronomic cost for such a ticket?
and similar to what the other person in this thread mentioned : those escape pods won't help during takeoff/landing phases.
