They can be stored anywhere. Sometimes at some quiet airport with space & minimal - if any - fees. Often they end up at the last maintenance place, grounded by the maintenance mob with a mechanic's lien waiting for the owner to pay for maintenance done, and the bank finally steps in. Then the bank finds they have an aircraft with lots of deferred maintenance, timex parts and sometimes missing parts/equipment 'borrowed' by the former operator 'temporarily' to keep something else flying to keep a cash flow going.
The maintenance mob I use for an aircraft I manage has one sitting there. They've been instructed not to release the aircraft and the bank is paying for the storage.
