Can you say FAE (fuel air explosive)? The key is not confinement,
but rather the speed of ignition, rate of burn & the concentration
of the flamable material to the oxident.

For the best, & prehaps most detailed explaination of this
try rec.pyrotechnics.

Would you like to tell that boy's family about his "alleged" death?  It
rattled buildings at least 65 miles away, because I live out in west Houston
about that far from the Brenham Oilfield site where it happened -- and it
was strong enough to wake me up.  Are you going to say that four million
people here imagined they heard an "alleged" explosion?  "Alleged", my ass.

Which it did, and it's almost a shame that YOU weren't there when it
happened...

Well, why don't you exert some effort for once and come on down here and see
for yourself -- or would that be too much trouble because it just might
conclusively prove that you have no earthly idea what you're talking about?
Be sure and tell those burn victims at Hermann Hospital here that their
injuries are "alleged", too...I'm sure they'll appreciate your concern.

No, but I can say "Killeen" :-)

Actually, there are Texans on the net who might have heard this
explosion if it could be heard for 140 miles. Both Austin and
Houston are apparently with 100 miles of Brenham.
