SRB's burn from the entire length of the booster from the inside out.  The 
solid fuel itself insulates the outer skin of the booster from the high 
temperatures within until the booster is almost burned out. 

A side note on booster destruct : the news last night showed this occuring
through blowing the nose cone and nozzle off and splitting the booster
itself lengthwise. However, I have heard frome another source (the net?) 
that only the nose cone and nozzle are blown off, and the exhaust is 
shot out the front and back of the booster.  Does anyone know which is
correct?
