Always surprised they closed GC, but the expense of converting it back to 'UK standard' (no doubt all on 110v for starters) probably would not have helped. The first time I saw GC was from the back of a Hastings (as a CCF cadet) when we joined the circuit behind a B-47 and ahead of a KC-97. At that time I had never even heard of Greenham as an airfield, even though we lived not that far away. The last time (as an active airfield) was taking a Chinook there for RIAT.
