12:46 - It probably could've been done, from a purely engineering standpoint (a number of bombers with multiple crew decks do manage to have ejection seats for all the crew, by building hatches and tunnels into the cockpit structure for the crew to eject through), but doing all that to the shuttle without prohibitive mass penalties (both from the seats and ancillary paraphernalia themselves, from the extra equipment and interlocks needed to keep the seats from going off while on the ground, in orbit, or during reentry, from needing more space elsewhere to place the systems and equipment that would've had to be moved out of the way, from the extra piping and cabling and whatnot necessary to keep that relocated equipment operational, from the extra structural-element beefing-up required to be able to reroute primary structural elements around the hatches and tunnels without weakening the orbiter's structure overall) would've been a massive headache, at best.
