A letter in your October 2018 issue talked about a P-38 firing on a flight of fighters and bombers. Your comment asked for more info. Martin Caidin mentions an incident such as this at length in his book Flying Forts. If I recall correctly, a YB-17 was outfitted as a kind of “Q ship” and ended up shooting the P-38 down.
