Where in N-Africa was that 190? Time?
Saturday 02 Jan 1943, III/SKG 10 targeted Bone Harbor. On the egress over Cap Rosa they encountered Spitfires which managed to get below the fighter cover and attack the bombers (FW-190G's).
During the dogfight, the collision occurred. The Spitfire spun off into the ocean.
Collision occurred at Cap Rosa and the pilot egressed to Sidi Ahmed. 242 Squadron was the most likely RAF unit for the encounter.
All the best,
Crumpp
