During the roll-out press conference last night, the Atlantis crew said that should the Shuttle become disabled during launch somehow, that the final crew member would get home something like 9 months later, having to wait his turn on the ISS for an open Soyuz seat.
But we all know that won't happen. Already got my name on the list for tickets. It really will be very sad to think there are no more shuttles. It is still hard for me to think that now two of those famous shuttles are out of service. No more Discovery, no more Endeavour, and soon no more Atlantis.
But we do have Orion to look forward to. Hopefully in five years or so we will see Astronauts going up in a new spacecraft from KSC.
