On June 21, 1944 at 2258 departed from Dunholme Lodge airfield in England, the Lancaster ND552 with the mission: a bombing raid on the synthetic oil plant at Wesseling (just South of Cologne) in Germany.
The aircraft was part of a formation of 133 Lancasters and 6 Mosquitos. 37 aircraft were lost during this raid, a very high loss rate, one of the highest during the war.
Also Lancaster ND552 was lost after an attack by German night fighters, it crashed in a Coal Mines site near Lanklaar.
Probably Lancaster ND552 collided with Lancaster LM434-KM-P which crashed to Lanklaar.
