I "flew" in a '78 Lincoln Continental Mark V once... (3 ton car) -- ramped over some steep rural railroad tracks. Lots of sparks.

There was the time we went out to a friend's land during a burn band and shot off fireworks in the middle of a field full of dry grass. Had to stomp out grass fires after each firework display
