Re: Is it possible to release the SRBs before they burn out?

With SRB thrust termination, I would think it would be possible to drop
them, then get off the tank. Would require a lot of work, but I would
think it's possible to detect a Challenger type failure and do something
about it in the 5-10 seconds from detection to failure. Personally, I like
talking about the what-ifs.

There have been a lot of interesting abort modes studied. One of the most
interesting was one that could handle the three engine out at liftoff
case. It actually made it back to the runway, three engine out RTLS. I
believe loads were acceptable too, as the vehicle never got above Mach 1.
But the region that this abort mode covered would have been rather small,
liftoff to 10-15 seconds, and it would have driven the Range Safety
Officer Crazy.

Well what do you know (section 3):

http://www.hq.nasa.gov/pao/History/rogersrep/v2appj.htm

"The Space Shuttle system design contains no capability to safely
accomplish a contingency abort while the SRB's are thrusting. There is
no capability to physically separate the SRB's from the stack while
SRB's are thrusting. Although the Orbiter can be separated from the
external tank (ET) during SRB thrusting, this action is not
survivable."

This statement is correct.
