Hi, all of ya,

It's not just a failure to ignite. I read somewhere the maximum survivable
SRB ignition differential is 100 milliseconds. If one SRB ignites more than
100 mS late, the vehicle will come apart.

So I guess it's too naïve to think that the live SRB could somehow be
jettisoned, left to blast off on its own?

The exhaust from the jettisoned SRB would rupture and ignite the ET.
That, and the whole shuttle stack sits on the SRB skirts. A minor point
in light of the first problem, but the remaining stack would fall over.
