First flight of the Boeing Vertol CH-46C Labrador helicopter.
This aircraft is a twin-engine, tandem-rotor search and rescue (SAR) helicopter used by the Canadian Forces from 1963 until 2004. It was a variant of the Boeing Vertol CH-46 Sea Knight designed and built in the United States. A search and rescue version was purchased by the Royal Canadian Air Force in the early 1960s and became known as the Labrador. Soon after, the Canadian Army acquired a troop and cargo version known as the Voyageur. In the mid-1970s, these army machines were replaced by CH-147 Chinook heavy lift and transport helicopters and the Voyageurs were transferred to the air force when Air Command was formed in 1975. They joined the Labradors on search and rescue duties and all were modified to a common search and rescue standard.
Picture above was taken at the Canadian Aviation Museum in Ottawa. From their website :
Labrador #301, the first to enter service with the Canadian Forces and the last to retire, was delivered to the Canada Aviation Museum in July, 2004 and marked the retirement from active service of the illustrious Labrador fleet. Its place in Canada’s national aeronautical collection is a tribute to the men and women of the Search and Rescue community who risk their lives on a daily basis to save others.
