Neither of those two areas dook.
Auxtank - It's done the reverse as it was built as a golf course, and then became an airfield.
Here is the zoomed out version of the first image I posted:
You can sort of see a golf course If you look at the airfield knowing that is what it was. The original club house is still around, and is in the middle of the marked region, which is thought to be an aircraft manufacturing facility.
The airfield itself is an industrial estate and the only remaining structure might be a couple of car parks at either end of the runway - or maybe the ramp..
One more clue to come and one more picture - the picture is a give away.
