In 1982 (iirc) an F-4D Phantom II from the Michigan Air National Guard collided with a private jet that was in restricted airspace near the North Carolina coast. The F-4D lost it's starboard wing up to the inboard weapons pylon. It landed safely and was later repaired by a depot maintenance team.
I saw the damage on this jet with my own eyes. Simply incredible that it made it home.
*edit* I was also on the flightline watching when this jet landed. Didnt think much of it when I saw it land, the F-4 was landing with its port wing towards me so I couldnt see that it was missing most of a wing. Only thing that made me (and the guys I was with) stop to watch was the firetrucks, ambulance etc that had been sitting and waiting. When this F-4 showed up, they all raced to the runway to meet it.
A few minutes later when our supervisor showed up in the line truck we asked him about the IFE that had just landed. Thats when we found out it was missing almost all of its starboard wing. A couple of days later that same supervisor drove us to the hanger it was in so we could see the damage.
