At Hawkinge there is still the BoB Museum, the camp cinema remains as do most of the accommodation, albeit i a very bad condition. The runways have disappeared under new houses, many of the street names are not even aviation related (PC gone crazy)
Barton le Clay. The first time i heard of it's existence was during an interview at Hamble. Ii must have overflown it many times and even looked on the ground but could find nothing. Not the best place for an airfield, with sharply rising ground on three sides.
Here is a lot of info and links to many other sites
Fly is probably well known to readers, but included an aerial view of the site of Barton, also another one as Luton Leagrave. I've never heard of that one either and the position shown is well outside Leagrave, nearer Dunstable.
