Default Delta IV Heavy Launch

That would require a catastrophic _rise_ in chamber pressure, not a drop.
If the chamber pressure drops on the SRB, it's not going to cause it to
explode.
(in fact, if it's severe enough it could cause combustion to cease in
the SRB - that was the concept used on the SRBs developed for the Titan
III C variant that was going to be used on Dyna-Soar and MOL, which had
blowout vents mounted at the top of the casing.)


That's actually a safety feature (of sorts), when the pressure drops
the combustion rate also drops. In theory this makes being around a
solid 'safer' and makes emergency response in the vicinity of a
recently violently disassembled solid 'easier'.
