When I was a snotty nosed APO at Tern Hill learning to fly the mighty radial engined Provost T1 the duty student was required to accompany the orderly corporal plus a couple of heavies and inspect the RAF sites that had fallen into disuse owing to the Germans surrendering. They had been kept going until the mid fifties and the inspection was to ensure that squatters had not invaded the premises; that's what the heavies were for.
They was one at Chetwynd consisted of a group of wooden huts with a tall fence around them that still had the standing orders and paraphernaliar dating from way back.
Five years later, learning to fly Sycamores it had all gone; just a grass field.
