Since when has the CAA been in existence to worry about fundraising?? Call me stoopid
but I thought one of its main purposes in life was to ensure the safety of aircrew, passengers and all those lovely people on the ground. I would say a Vulcan was a bloody dangerous aircraft to fly when it was in service, let alone after many years mouldering on the ground. There's no way you can compare a Lancaster with four lovely Merlins to a Cold War monster with thumping great jet engines (Olympi??)
IMHO, I would be pretty surprised if the CAA allowed it to fly at all, especially from a British airfield where you are inevitably flying over the general public whichever direction you take. Way way too risky, and that's definitely not in the CAA's job description.
Dream on, guys...
