I don't know that they haven't been allowed back. Do you? Who is stopping them returning? Is it temporary? Why?
Do they take off on taxiways, fly low level past the Coastguard helicopter, do aerobatics in the overhead?? Tell us what the problem is. From the information given we have no idea of what you are accusing them of. As for Carill, whenever I've been to Lee the place looks deserted and Carill aviation aircraft have their covers on.
