*boom* indeed.

You could see visable shockwaves knocking things and building over in there. That must have been one hell of a fire.

When I was a kid, my father was an EPA-sort on Fort Carson down in the springs.

One time he was doing a noise-monitoring study to determine how the noise from soldier's training on the firing range affects surrounding business/etc (some were chip plants and the like, very unhappy when there were seismic events from large bombs).

I got to go onto the bombing range when they were doing the study. We stood on a hillside while A7's dropped pairs of 1,000-lb bombs left over from Vietnam onto a derelict tank target on another hill about 1km away. The idea was to use ordinance that generally exceeds what they usually use to get a good baseline for the worst case scenario.

Noise docimeters were arranged throughout the area, including at various points in the city outside the base.

the planes would swoop in, deliver their payload (remarkably well-on target), there'd be a great mushroom cloud of fire, and then... *KERFOOOOOOOOOOOOOOM*, a shockwave that is much more felt than heard.

It was incredibly awesome.

I also ran around collecting magnesium sabots and hiding them in the truck for later fun with an acetylene torch and a garden hose, but that's another story.

Also found a nifty electrically-fired grenade simulator that hadn't gone off. Set that off in my back yard at midnight on New Years. All around the neighborhood is the *pop*pop*pop* of bottle rockets. I touched the contacts (wired through an extension cord) to the car battery and *KERBOOOOOM!*... the neighborhood got reeeaaal quite for a moment. Went out the next morning to find a snow crater.

I think I'm a little more horrified than awed.. man that's a huge waste of fuel. :(
