This Avro Lancaster Mk I R5868 was on display at RAF London.
The Avro Lancaster is a British Second World War heavy bomber. It was designed and manufactured by Avro as a contemporary of the Handley Page Halifax, both bombers having been developed to the same specification, as well as the Short Stirling, all three aircraft being four-engined heavy bombers adopted by the Royal Air Force (RAF) during the same wartime era.
The Lancaster has its origins in the twin-engine Avro Manchester which had been developed during the late 1930s.
It first saw service with RAF Bomber Command in 1942 and as the strategic bombing offensive over Europe gathered momentum, it was the main aircraft for the night-time bombing campaigns that followed.
As increasing numbers of the type were produced, it became the principal heavy bomber used by the RAF.
