Slightly different Challenger question - what could have happened if the SRB breach had faced outboard, away from any attachment fittings or the ET? Would the SRB have failed completely prior to separation (leading to a similar outcome)? Would it have caused significant guidance issues? Would they have had more time to execute some emergency maneuver?
Would abort to orbit have been possible?
I realize this is impossible to answer definitively, but I find myself curious as to what could have happened.
