I'm sorry to say that, but it seems were talking about a backyard with some remains of a former airfield
in the middle of a village.

In all honesty this is neither the right place nor has this museum a future - because of the location.
Afaik, there are plenty of bigger sites outside villages rotting, maybe it's time to move on and focus on one of those?
