Ok this may sound a mad idea... but I think it could work.
Newquay has a grat site and runway, why not use it to its full potential and let Newquay become a transatlantic hub?
Fly to Newquay from across the atlantic and then a fleet of commuter aeroplanes at Newquay could service several destinations all over the UK (and Europe?).
Hathrow and Gatwick are full, and just how many people who fly into heathrow are visting London or even the UK anyway?
Just some "Blue Sky" thinking.
Now taking cover ready for the replies...
