Great memories Milt.
Of ETPS the hangar is still there. It was used as the main civil hangar until the new complex was built northiside around 3 years ago. It is now just used by the BAe comm's flights who's HQ is now in the ajacent old Comet water tank area.
Codys tree was replaced by a metal replica in the 1960's. Some of the original still remains with museums. The replica was moved from outside the black sheds to the new MoD site in 1997. There is now a good museum in G1 building( the RFC WW1 HQ on Farnborough Road), it has a couple of Hunters,Lightning T5, Jaguar, Gnat and some noses.
Aircraft used to mistake Blackbushe for Farnborough until the ILS and decient(??!) radar were put in when the airport became civil in 99. Although it seems that Northolt will close and 32sqn/Queens Flight will move in next year. So it may become partially military again?
Keep those memories coming.
