Finnish B-239 (serial no. BW-372) flown by Lt. Lauri Pekuri was damaged by a Soviet Hawker Hurricane and crashed in 1942 on Lake Big Kolejärvi, about 31 mi (50 km) from Segezha, Russia and was rediscovered in 1998.
A Finn flying for the Nazis in an American plane was shot down by a Russian in a British plane.
Nice. I missed the British plane detail.
