A rare behind-the-scenes look at a Cold War spy-plane base
During the Cold War, American spy planes were based at RAF Alconbury in Cambridgeshire.
Flying stopped at the base in the 1990s and part of the site is being redeveloped as housing.
Its blast-proof bunkers are rarely glimpsed by the public, but BBC Look East was given a behind-the-scenes tour.
