To me, this means they waste some significant fraction of the SRB >thrust after separation. Is that really true? The SRBs may still be burning when they are jettisoned, but they may not be producing USEFUL thrust. If the thrust from an SRB is less than its combined mass and contribution to atmospheric drag, it is dead weight, and actually detracts from the useful payload, since the SSMEs must carry the difference. ===================================================================== Norman Kluksdahl ...!nuchat!moe
