My ROTC XO (and Top Gun movie "MiG" pilot) told me a story of someone shooting themselves down in a F-4 in the PI. I think it was him, but it's been a while since I heard the story, so I don't want to give a bad sea story. Whomever it was, the Sparrow left the rail and did its pitch up WAY too early and took out the nose gear. After landing, sliding to a stop and exiting the aircraft (which was apparently its own ordeal since the F-4 didn't have the juice to open the canopy), the local PI crash crew decided that NOW was the time to let loose with the water cannon, blowing the pilot off the top of the aircraft (again, I'm pretty sure it was my XO) and breaking his leg.
So yeah, shoots himself down with his own missile. Lands with no nose gear. Gets out of the aircraft, all without a scratch, then breaks leg on egress thanks to the crash crew. Pretty good sea story, though.
