P47 Thunderbolt Crash, 30 September 1943

Two P47s of the USAAF collided over Holland.
One crashed at Herpen. The pilot, Lt. Col. Melvin F. McNickle, was captured and became a prisoner of war at Stalag Luft III.
The second plane crashed into the Zuider Zee. The pilot, Lieutenant James F. Byers, McNickle's wing-man, was killed. The wreckage was located in 1976.
McNickle's career has been extensively documented, here, and here.
