Angus Johnston was born on 6th June 1921 in Little Harbour, Prince Edward Island, he was the son of Daniel and Mary Johnston (nee McAuley). After leaving school he had worked as a carpenter and labourer. His father died when Angus was young and by the time Angus joined the RCAF his mother had remarried Mr Peter Mossey, also of Souris, Prince Edward Island. Angus enlisted for RCAF service on 12th June 1941 in Halifax, Nova Scotia and trained as an air gunner in Canada, receiving his Air Gunner's badge on 25th September 1942. He arrived in the UK on 5th November 1942 and was later posted to 23 Operational Training Unit (23 O.T.U.) on 23rd February 1943 where he joined Thomas Kneale's crew as rear gunner. He then flew with Kneale pretty much constantly after this joining 426 Squadron on 14th May 1943 and until their deaths in the Yearsley accident later in the year. He was granted a commission to the rank of P/O on 18th September 1943. There is some confusion as to whether he was the rear gunner when the aircraft crashed at Yearsley though. He and Sgt Fortier may have switched positions in October 1943 with Gus Johnston becoming the mid upper gunner in the Lancaster.
At the time of his death following the accident at Yearsley he was on his sixteenth operational flight. He was twenty two years old and buried with other members of his crew at Harrogate Stonefall Cemetery, Yorkshire.
