As for the use of the hangars, I don't know, could be Weston for GA (they've asked their clients before if they would opt for hangarage were it available, I think the vast majority said yes), it could be Sycamore as they would really benefit from a hangar that could fit their aircraft straight in rather than having to chop the tail off first or they could use it as bait to try and attract a new air operator.
