I don't know they can be quite resilient, one VGS had no hangar for 4 years, one has been off their airfield for over a year due to it not being maintained and flooding all the time, anotherwas shut for 10 months while they changed aircraft and moved location, another is displaced from its catchment area by hundreds of miles and one had no winch for months before this "pause" they put up with quite alot and still keep going
