Mark Six, the old burning Kiowa story is a beauty all right - I bet the man in question wasn't laughing at the time though!
I'm not sure if this was after you left for greener pastures, but remember the infamous exercise at Shoalwater Bay when not one but 3 Hamel artillery pieces were totalled?
One was mysteriously pickled from under a Blackhawk for no apparent reason - the pilots both swore they hadn't been near the switches;
the second one was being hooked up for an NVG move when part of the ADE got hooked around the gun, and the pilot pickled it when it started to swing wildly from side to side;
and the poor old artillery lost one themselves when they were manhandling it around on a hill, it got away from them, rolled away and smashed itself up.
I don't think they were real cheap, either!
