I remember Elvington from the 80's when it was releif landing ground for 7FTS based at RAF Church Fenton. When a course was almost ready for first solo, they would deploy with 2 a/c to Elvington and spend the day in the circuit, leaving CF for the more advanced studes. Everyone who went solo at Elvington, including me, had a cerimonious dunking in the water resevoir by air traffic!
