Royal Air Force Regiment Catterick served as a regimental depot of the RAF Regiment occupied by operational Squadrons and was the training base for the RAF Regiment from 1946 to 1994 when the Regiment's training facilities moved to RAF Honington. Catterick was also the training centre for the RAF Fire Service as the RAF School of Fire Fighting until the 1990s. As a fire school it had a "rescue set" the mock up of a house to simulate search and rescue scenarios. It also had a burning area where ex service aircraft were covered in fuel and set alight including in 1983 two complete Avro Vulcan bombers. The Vulcans were only able to land after the closure of the A1 and the clearing of the fields on the opposite side of the road. The aircraft had to fly as low to the ground as possible well before crossing the perimeter of the airfield and touched down at the furthest possible extremity, in order to be able to stop safely before running out of runway. There were also a number of retired airframes used for practice rescues and deployments. The Fire Fighting & Rescue squadron moved to RAF Manston
