Narrative:
Avro Lancaster B Mk. I NN808/TW-L, 1660 HCU (Heavy Conversion Unit) RAF: Written off (damaged beyond repair) 20 June 1945 when crashed on approach near RAF Swinderby, Lincolnshire.

Lancaster NN808 was airborne from RAF Swinderby at 14:11hrs on a conversion training sortie with nine crew on board. At approximately 17:10hrs, while on approach to RAF Swinderby, with the port outer engine feathered, the port inner engine feathered itself. This caused the port wing to drop until it was nearly vertical, the nose dropped, and the Lancaster dived into the ground from an altitude of 50 feet, killing seven of the nine crew on board
