Aircraft Type and Background
RAF Consolidated LB-32-2 Liberator Mk I / AM915
(This aircraft was built originally as USAAC B-24, serial 40-2353)
Type Nickname: "Lib"; "Lumbering Lib"; "Flying Boxcar", and others.
The Consolidated B-24 heavy bomber first flew in 1939. The
prototypes were equipped with four Pratt & Whitney 1200hp R-1830-33
Twin Wasp engines. Early production versions were fitted with P&W
1200hp R-1830-41 engines with GE turbo superchargers. Later
production versions (B-24Ds) were fitted with P&W R-1830-43 engines.
Later variants followed. Their maximum speed was about 487km/h
The RAF gained extra B-24s when they took delivery of an order
destined originally for France. Consolidated termed the B-24
aircraft destined for Britain 'LB-30As', as they had been modified
to meet British MoD and RAF requirements. The RAF assigned the name
Liberator to their new bombers (a name adopted later by the USAAF).
Three Liberators (AM915, AM918, and AM920) were converted from their military role to operate with BOAC in a civilian capacity. These aircraft were used to ferry priority passengers and crews across the Atlantic. The Liberator featured on this page was one of these aircraft.

Aircraft Accident Details
At the time of this accident, the Liberator was being flown by BOAC pilots in conjunction with RAF Ferry Command crew.
The Liberator had been enroute from Montreal in Canada to Prestwick in Scotland. However, as Prestwick was closed for maintenance, the aircraft was instructed to land at nearby RAF Ayr (Heathfield).
While receiving landing instructions, the pilot requested weather conditions for RAF Stanley Park or RAF Squires Gate near Blackpool. In view of the cloud cover prevailing over Ayr at the time, the pilot considered that it might be advisable to land at an alternative airport.
The Liberator flew over RAF Ayr (Heathfield) and then began turning to head southward for Blackpool. At the time, the pilot believed he was turning over water. In fact, however, he was circling over the Kintyre Peninsula. Very soon, the Liberator struck the east shoulder of Achinhoan Hill at the head of Balnabraid Glen and not far from Arinarach Hill near Campbeltown.
The aircraft disintegrated on impact, killing all 10 personnel on board.
