Pobjoy, yes please!
Brokenlink, I thought that was what you meant, but just in case anybody else thought the airfield was abandoned!
I doubt it could ever be resurrected as a powered aerodrome - I have seen the odd Cub and Cherokee land there in the past (not sure if they were precautionaries?) and SHGC operated a Falke a year or two back for a while. The site is (mostly?) owned by the Coroporation of London and maintained as public common land outside of the peri-track which I imagine would preclude use for powered aircraft on a regular basis. We had another thread on this forum several years ago...
