I recall doing a see-in for a singe seat OCU Jag back in 1984, after shutting down the pilot came round the nose and walked down the side of the aircraft. As I was helping the tanker driver get the hose on he suddenly appeared again and said "you may want to leave that just now, I almost shot myself down over the range and it went through the engine door...."
Sure enough, there was a nice little hole through the outer skin of the starboard engine, if it had gone through the inner skin it would have mangled the fuel management system
