I am pretty sure there are ways to distinguish between plastique and various
petrochems exploding.  They explode quite differently.  For example sewer gas
probably would not destroy the sewer cap... instead it would knock it up into
the air.  On the other hand c-4 would frag the sewer cap.

It's the speed of the explosive reaction and the distribution of force that
matters. Petrochemicals burn rather slow, while c-4 is faster (the nitrate
groups are what do it).

I swear, I am learning so much from being on this list. Especially
from this thread. This is great.
