This was sent to me by a friend recounting a story.

So we are up in the mountains at about 0100 hrs looking for a bad guy
that  we thought was in the area. Here are ten of us, pitch black,  crystal
clear night, about 25 degrees. We know there are bad guys in the area, a few 
shots have been fired but no big deal. We decide that we  need air cover
and the only thing in the area is a solo B-1 bomber. He flies around at 
about 20,000 feet and tells us there is nothing in the area. He then
asks if we would like a low level show of force.

Stupid question.   Of course we tell him yes.

The controller who is attached to the team then is heard talking to
the pilot. Pilot asks if we want it subsonic or supersonic.

Very stupid question. Pilot advises he is twenty miles out and stand by.

The controller gets us all sitting down in a line and points out 
the proper location.

You have to picture this. Pitch black, ten killers sitting down, 
dead  quiet and overlooking this about 30 mile long valley.

All of a sudden, way out (below our level) you see a set of four 200'
white flames coming at us. The controller says, "Ah-- guys-- you might want to
plug your ears". Faster than you can think a B-1, supersonic,  1000'
over our heads, blasts the sound barrier and it feels like God just  hit you
in the head with a hammer". He then stands it straight up with 4 white
trails of flame coming out and disappears.

Cost of gas for that: Probably $50,000
Hearing damage:  For certain
Bunch of ragheads thinking twice about shooting at us: Priceless.
