there. The city was the site of the 1954 mid-air collision of Trans-Canada Air Lines Flight 9. Military presence The area surrounding Moose Jaw has a high number of cloudless days, making it a good site for training pilots. The Royal Canadian Air Force under the British Commonwealth Air Training Plan established RCAF Station Moose Jaw in 1940. After the war, the RCAF remained in the community and used the facility for training pilots through the Cold War. The facility changed its name to CFB Moose Jaw in 1968 and is now Canada's primary military flight training centre and the home of 431 (Air Demonstration) Squadron (aka the "Snowbirds"). CFB Moose Jaw's primary lodger unit is "15 Wing". In the Royal Canadian Air Force the lodger unit is often called 15 Wing Moose Jaw. The base usually holds an Armed Forces Day each year. The Saskatchewan Dragoons are a reserve armoured regiment with an armoury in the city's north end. Royal presence Moose Jaw has been visited by many members of the Royal Family. Edward, Prince of Wales, who owned a ranch in Pekisko, Alberta, visited in 1919, 1924, and 1927. Prince Albert, future king and father of Queen Elizabeth II, paid a visit in 1926. King George VI and his wife Queen Elizabeth (later known as Queen Elizabeth, the Queen Mother) visited during the Royal tour in 1939. Queen Elizabeth II first visited in 1959, and has come to the city a few times since. The Earl of Wessex (Prince Edward) became Colonel-in-Chief of the Saskatchewan Dragoons of Moose Jaw on visiting Saskatchewan in 2003, when he congratulated the regiment on its "contribution to Canada's proud tradition of citizen-soldiers in the community." Involved in peacekeeping operations in Cyprus, the Golan Heights, Bosnia and Croatia, the regiment has also provided aid during floods and forest fires in the prairies. The Prince returned to visit his regiment in 2006. The Earl of Wessex also inaugurated the Queen's Jubilee Rose Garden in Moose Jaw on his visit in 2003. Other royal connections to the city include King George School and Prince Arthur Community School, both named for members of the royal family. Before it shut down and became the separate Cornerstone Christian School, the South Hill school was formerly named King Edward Elementary School.
