Efortless,
I'd try and have a word with the administrator/liquidator, despite the general conception of them being ogres they have nothing to gain by inhibiting potential trade.
If you owe any money at all to the airport company, (and that includes, for example, if you rent hangerage from a company which owes the airport company money) you'll be obliged to cough up before you can go ove your remove your "chattels".
On the good side, the liquidator will treat Shoreham Airport as a separate, viable company and look for a buyer ahead of the holding company's less viable assets.
That means, for good or bad, Shoreham will be sold off as a priority.
