Has anyone made use of http://www.historicaerials.com/?
I had a look at what is available for some airfields and in some cases there is something for each decade from the 1940's to the '00's.
The only problem is that each frame is around £75 to £171, too expensive to even consider and to get total coverage would be around 4 frames!
Has anyone bought any 1940's 1950's aerial photos and if so where from and was the price reasonable?
I did get 5 aerial photo's of the area around my house in photocopy form from English Heritage for £15 cover 1947 - 1990 but that service seems to have stopped.
