AirUK - go and look at the various maps on the web site I linked to - I can't post screenshots due to copyright - edit to add: posts crossed.
In the area next to the Viables cottages there doesn't seem to be anywhere to store an aircraft, whereas there are a number of possibilities around Hatch Warren Farm. I also think that area around the cottages may well have been built over by 1979, whereas the building work seemingly hadn't got to Hatch Warren farm by 1983.
Edit to add:
If you slightly click away from the area you are interested in, you can sometimes get a different choice of maps to look at.
