I am privileged to fly at Halton as a member of the RAF flying club there and I don't think the situation is quite that bad. The airfield is in regular use by RAF Gliding and Soaring Association, RAF Halton Aeroplane Club, RAF Halton Microlight Club and and ATC Volunteer Gliding School (if they ever sort the mess of privatised maintenance). It is also used for training by the transport helicopter squadrons. The airfield itself (not the same one as 1913, that is now the parade ground) is in beautiful condition and has over very recent times had drainage, fuel farm and other improvements. There is an excellent and improving museum on the main site and the trenches are preserved. The old hangars are a bit tatty but serviceable, I was in "ours" only yesterday for our annual aeroplane polishing morning while the airfield is fertilised by hundreds of local horses there for their annual pony club event around the airfield.
