Tarrant Rushton
I joined FRL in 1966 and, although the airfield was in regular use by their Meteors and Canberras, it was no longer in use as a diversion for V- bombers. It had been used by Valiants well before then.
I imagine that Sir Alan Cobham was very keen to maintain this function for Tarrant as it would have helped him win the famous Critchel Down case which led to Tarrant being restored to agricultural use after 1970. As the land was no longer being used for the "defence of the realm", Lord Cranborne won it back.
