Narrative:
Avro Lancaster B Mk. III PB733/GP-P, 1661 HCU (Heavy Conversion Unit) RAF Winthorpe, Nottinghamshire. Written off (destroyed) 2 May 1945 when crashed at RAF Winthorpe, Nottinghamshire. Undercarriage collapsed on landing & DBR.

Took off from RAF Winthorpe at 22:58 for night circuit practice. Came into land at 23:08 but the pilot at the controls misjudged his height and levelled off too high. As a consequence, the bomber thudded on to the runway with such force that the oleos were completely smashed.

Flight Lieutenant A J Keins RAAF (Safe)
