Puujiikoo got it, IWM Duxford. Coordinates:

Longitude: 0° 7'44.51"E
Plenty of planes, zooming in reveals atleast a B-17, VC-10, Orion, Shackleton, Victor, F-15... Also plenty of vechiles. Might be quite old picture because there might be a Blenheim in flying condition in the right (might be also a Anson).
