I was 'selected' at Hornchurch and Daedalus House. South Cerney I visited frequently when a RCT TA Movements Officer and it was the Air Mounting Centre. Our RCT(V) HQ was Prince William of Gloucester barracks, formerly RAF Spitalgate. The Colonel was not impressed when he asked if I had visited in my RAF days and I admitted "Over the wire when it was the WRAF Training Centre"
