ATB, the incident at Paris was an Embraer Tucano - the way I heard it, a member of the ground crew was standing on the seat when it was triggered - don't know if that is exactly the story. A friend of mine was at the show, though fortunately didn't witness the incident, and told me the story later.
I also once heard a scurrilous story involving a Sea Harrier, an airshow, a small child and a hangar roof, but I don't belive that one for a minute!
