For example, you might record a
75mm Howitzer (when you want to play at being a B-25H pilot), a
'bombs-away' whistle/kaboom to wake up the neighbors, various engine
sounds (for example, a B-36 on takeoff from the CD available at
http://www.b-36peacemakermuseum.org/ or
http://www.cowtown.net/proweb/lastb36/), sonic boom, etc.

Can you imagine a late night take off from a grass strip in the middle of
Sheepville with the sound of a B-36 taking off? I bet the UFO 'experts' will
use it for 'proof.'
