Simon,
Does Newquay have a need for two commercial aerodromes ... is there so much air traffic around that two Newquay aerodromes are needed to meet with such demand?
Once the closure of RAF St Mawgan airfield was announced Corwall Council could have weighed up the options, got their abacus out, and easily realised that over the years a St Mawgan commercial airport will cost them, cost the taxpayers, 10's, indeed 100's, of millions of pounds ..... meanwhile UK doesn't have the means to defend it's own airspace and is sailing an aircraft carrier around for the next 10 (ish) years without any fixed wing aircraft to put on it!
Cornwall Council should be looking for a long term solution and there is one commercially successful aerodrome to the south of Nequay, it makes it's own living, it is self supprting and give it a one off investment to upgrade it to 'airport' status then Council can wipe their hands and walk away.
Meanwhile to the north of Newquay there is a white elephant of an aerodrome that has never been commercially viable, requires millions of pounds of taxpayers monies, year in, year out, just to keep it open, well let's say all of these annual millions were coming out of your pocket, you wouldn't be so keen to keep it open for any longer than is necessary would you Simon?
