 It was not until 1978 that any formal attempt was made to investigate the wreck, and its identity has not been absolutely determined.Amongst the wreckage a Royal Canadian Air Force cap badge was discovered, which suggests it may have been LA995 which lost during a flight on 28 September 1943.In 1955 the British government decided to incorporate St Kilda into a missile tracking range based in Benbecula, where test firings and flights are carried out.
