Parachutes - really? If you got into a deep doodoo stall would you really have time to use them? Surely it would take a long time to get to the F/D door, get it open, get to an exit, jettison the door and jump out with sufficient height left for the parachute to open?
BTW, didn't one of the Concorde prototypes have an escape chute?
