On the night of 11th Feb. 1941, 79 Wellingtons. Whitleys and Hampdens set off to bomb Bremen and, of these, only 27 claimed to have reached the target. On the return 22 aircraft were lost when thick fog blanketed their home bases making navigation very difficult. Whitley V P5013 from 51 Sqn. at Dishforth got lost and the crew parachuted to safety, with the aircraft finally coming down near Hatfield, East of Doncaster. This Merlin X Single Stage engine was recovered at the crash site from 18ft of clay in 1987 and is now on display at the South Yorkshire Aircraft Museum/Aeroventure.
