We are now going to put a big chain around the rotorhead of the next heilcopter that lands without permision or good reason and charge £500 a day parking and the chain will not be removed untill the fee is paid in cash.
For you pilots having problem with your rotorhead getting chained up here is an solution for that and its even cheaper than the landing fee.
only $229
can fit in most cockpits or cargo holds
