Kolibear,
I flew the Sea Fury in the Drumhead Review. The Corsair, Lancaster, Spitfire and Huricane were all scheduled to fly but couldn't take off because of poor weather. The Sea Hawk was U/S, there are no airworthy Swordfish in the UK until next season and the Avenger was U/S I believe.
Any of the other aircraft you mention were also primarily Duxford based which would have also cancelled as the Corsair did.
Nothing to do with money, nothing to do with civilians not taking part in public displays (it matters not whether the display is military or civilian, it's a CAA approval and insurance issue.)
As for relevance? All of the aircraft that flew were naval combat aircraft. I think you mean you wanted to see more. So did I.
