Okay-you'll hear enough about this in the days to come, and, while I often agree with him, MichaelEdward is waaaay off-base.
First off, I'll point you towards this post.
The fact is, properly packaged, one gallon of gasoline , which weighs about 7 lbs., has ten times the equivalent weight of TNT-by international treaty, TNT is defined as having 1 calorie of energy per gram, while gasoline has roughly 10 calories per gram. What this basically means is that 50 gallons of gasoline, properly packaged, is the equivalent of 3500 lbs. of TNT-almost two tons.
The additional propane, as others have pointed out, is significantly worse.
Add to this the shrapnel, cell phone hookup and runaway driver, and you basically have one of the very same IEDs that are killing troops in Iraq.
Add the reports of "smoke" (probably propane vapor-scary!) in the vehicle, and you have a pretty urgent situation.
Apropos of everything else, the typical procedure for devices-the most common one-is to take the damn thing away from people and blow it up. Or just blow it up. The romantic notion of going in and clipping wires, while part of the training, is just not the usual procedure followed.Of course, in situ detonation and removal were not options in this case, so it had to be disarmed. The tech and his partner who actually had to do this, with what was probably propane vapor all around him, knowing that he'd either save some lives or be vaporized, is to be commended.I'd wager that none-or maybe one- of you can even begin to imagine how scary it was for them.
