A commemorative service has been held to mark the 75th anniversary of Lancaster R5672 crashing onto the North Kelsey Road at Caistor.
The service was led by Canon Ian Robinson, and in attendance were Mr and Mrs Biddells, on whose garden wall the memorial is situated, and Tim Stone from East Kirkby museum, who assisted with much of the initial research into the incident.
Beverley Hines, a granddaughter of Harold Quinton, who perished in the crash, also attended the service, and good wishes were received from Marjorie Stonehouse, the twin sister of the captain WC Eric Campling, who at 99 plus was unable to travel.
It was at 16.40 hrs on Saturday April 8, 1944 that Lancaster 1 No R5672 from No 1 Lancaster finishing school, RAF Hemswell crashed onto the south east corner of RAF Caistor.
The aircraft was seen to do a low turn over RAF Caistor, then there was a massive explosion and the aircraft disintegrated just above the tree tops on the Caistor to Kelsey Road.
Fragments of wreckage were blasted over a large area.
