This design is based on Lancaster “AJ-N” (serial number ED912) flown by Pilot Officer Leslie Gordon Knight, during Operation Chastise (also known as the “Dambusters Raid”). Operation Chastise was an attack on German dams carried out on the night of 16/17 May 1943 by 617 Squadron RAF Bomber Command, using special "bouncing bombs". Lancaster “AJ-N” successfully bombed the Eder dam, causing it to be breached and safely returned to base.
