Thanks The SSK for posting the map. I always wondered where London Air Park was.
The map answers a few questions I had.
I like the pictures that have also been posted.
It would appear from the old pictures (I could be wrong) but the north East - West runway was in use first with some sort of terminal to the north of the runway.
If I use a recent map (like flash earth) I can see various taxi ways running North of the runway up to the edge of the airfield now where northern perimeter road is, it would appear that a terminal existed there.
location :-
Flash Earth ...satellite and aerial imagery of the Earth in Flash
Comparing the previously posted pictures it would also become apprent of the extension to the runways as well (extended further west).
If I am wrong then please correct me.
