served with 115 Air Transport Unit of the United Nations Emergency Force (UNEF), on the Sinai Peninsula, where he flew de Havilland Otters and Caribous. While with 115 ATU he acted as Under-Secretary-General of the United Nations Dr. Ralph Bunche's pilot. On 4 July 1964, Garrison captained the RCAF's final flight of the Avro Lancaster with Flight Lieutenant Ralph Langemann as co-pilot. Specially authorized by Minister of National Defence, Paul Hellyer, the flight was complicated by the fact that Garrison had never flown a Lancaster and had broken his ankle the previous day. It displayed at the Calgary International Air Show, an event created and coordinated by Garrison. After the flight, Garrison purchased the aircraft, KB-976, which is now included in Kermit Weeks' Fantasy of Flight collection in Florida. During 1965, Garrison, with authorization from Paul Hellyer and the help of RCAF 121 Search & Rescue Unit, salvaged a Vought OS2U Kingfisher from Calvert Island, British Columbia, It had crashed there on a ferry to Alaska during World War II. The aircraft was brought to Calgary, then restored by the Vought Aeronautics 25 Year Club and donated by Garrison to the North Carolina Battleship Commission . It is now displayed on the stern of the USS North Carolina. In his classic, Fighter Command Air Combat Claims, 1939–45 (1939–1940), John Foreman commented on the question of pilot temperament and ability. Foreman observed that Garrison had remarked, "In every squadron there were, perhaps, four or five pilots who exuded confidence. They knew that they were going out to shoot. The rest knew sub-consciously, that they would make up the numbers, mill about, and get shot at". Post-military career In 1960, Garrison obtained a contract to ferry 75 ex-RCAF P-51 Mustangs to new owners in New York. Milt Harradence took time off from his law practice to accompany Garrison on the trips. Flying mainly without radios, they navigated by following the Canadian Pacific Railway tracks eastward. Harradence and Garrison acquired two Mustangs as part of their compensation and registered them RCAF 9221 44-74435"CF-LOR" and RCAF 9223 44-74446 "CF-LOQ"; the first of their type registered in Canada. During 1961, while ferrying surplus RCAF Mustangs from the old BCATP airfield at Macleod, Alberta, Garrison spotted a number of Lancaster bombers slated for the melting pot. He purchased Lancaster FM-136 and created the Lancaster Memorial Fund to see the aircraft on permanent display in Calgary. His
