There are two aerodromes in this image.
edit to add: I think this is only the southern portion. The majority of the first photo is just off the top of this image.
Further edit: This is the southern aerodrome. Mostly gone by 1944 - Bits of it appear in the first image where it the interesting rail layout was noted.
