Cumbrian,
The USAF base down the road was called Burderop, It closed down wee back, Was used as a school for a while, then when the school moved it became a hospital for the disabled so I would say the USAF went from there early to late 60s. I was at school there 1965 till 69 when the school moved, worked there as a volunteer till I joined up in 71. Spent time in most of the RAF hospitals both for socialising and for injuries caused by too much sport, was looked after well each time. Was a brat at Halton and stationed at Lyneham so used both the NAAFI,s as social areas!!!!
