When I was in the USAF stationed at RAF Upper Heyford I lived in a house adjacent to RAF Bicester. At that time there were a bunch of old red brick three story buildings that had been abandoned, but were still standing.
There was a very active glider operation at the old airfield.
I used to sit in my back <strike>yard</strike> garden watching gliders turning base to final right over the rooftops.
Do they still operate gliders from Bicester?
