Had a sortie in a p51B. Took a hit from a p47 but didn't notice anything fall off. It was a loud "BANG" (the kind that signifies you just lost a part of your plane) but I was fine, and kept flying. Moments later this nagged at me so I hit CTRL D and it said I had a pilot wound!!!
No blood on the canopy at all! Had I seen the blood I would have left for base faster. As it was I wasted time and bled to death while rtb.
Just FYI.
