Thanks. I sent a copy of one particularily thorough response to Ken Scofield, who was asking about this in the first place, and he still had the following comments. Many of you said that you just can't separate the entire shuttle from the SRBs & Tank while the SRB's are firing ... and I believe you ... but maybe someone could elaborate on the specifics. Please copy Ken directly (and me if you don't post) on your response as he does not have access to the net. Thanks.

Why not just jettison the entire shuttle craft from the tank/booster assembly? As I see it, the tank/booster assembly would just continue on its merry way until it self-destructed, but the shuttle could glide off into the sunset (sunrise?) and live happily ever after. Two arguments I've heard against this are: The shuttle would break up due to aerodynamic forces, and/or it would be burned up in the departing booster's firetail. Neither of these set well with me, because (a) the shuttle is designed to re-enter the atmosphere in excess of Mach 25, and (b) do so with skin temperatures of several thousand degrees. So, what's the big problem? You may post this one, too, if desired.
