A_A, certainly most of it.
If their airfield is closed then they will have to lob in somewhere else. It's not just the 10 or so aircrew
but fire, crash, medical, supply, eng ATC, ops, all of whom will have some presence on the ground somewhere in UK.
If the event was at an airfield and the airfield put on a bloody good aftermath party then you would get volunteers for the static and spare etc. As they is no landing area what exactly are they expecting?
Lots of cooks cooking burgers in CS95 and white hats? Lots of whatever we have spare making look like a workshop?
