Well, I've crashed my ship into a station wall a few times, but I don't count those as deaths, since if your ejection system can't work then, what the heck is the point of them?
In combat I've only been shot down once in combat, though I've had my thrusters blown out by a pirate in another instance (but I repaired and moved on). And another time I let myself get shot down for the sake of a GalNet Youtube video I was putting together.
Since I'm using my own version of Ironman via the Pilot's Ejection Table (

But yeah, I've rammed stations stupidly a few times, always because of a stupid boosting maneuver gone wrong, and almost exclusively in an Asp, because it flies like a brick.
