But Skybus did own/operate LEQ and I understand that they told the PZE helicopters to "Pze off, you're not operating from our airport", I'm not sure about the owner/operator of LEQ now but I'm presuming that it remains a closed shop. If they did that (and did it in the past- if your claim is correct) they would be/have been in breach of their airport operating licence from the CAA.
Land's End Airport is owned by the Isles of Scilly Steamship Company, a.k.a. Isles of Scilly Skybus, as Lands End Airport Limited.
The airport has a Private Use Aerodrome Licence that allows flights only as authorised by the licensee.
It's a closed shop!
