I've just found out that one of our Class 1 staple airports, Plymouth City, was closed in 2012.
I realise we (the VA) operate in a "fantasy world", but it was always one of my great pleasures to hop from Plymouth to Edinburgh when testing aircraft. Now, should I want to maintain reality, that option is gone.
IRL, when flight to/from London were withdrawn in 2011, daily passenger numbers declined to the point where it wasn't economic to keep the airport open.
