RAF Stratford on Avon
I think you are talking about the airfield just off the Shipston Road out of Stratford on Avon.
You can see the outlines of the runways on Google Maps, not much of the other infrastructure remains.
I recently worked for an engineering comapny based on this site and one of the workshops was the old Officers Mess.
An interesting building with a number of ghosts.
Also the airfied is the site of the tragic fire where 4 firemen died.
I live a short distance from RAF Snitterfield – currently home to the Stratford on Avon Gliding Club.
Hope this is helpful
