The fact is that Gatwick IS in the wrong place, but it's not the only one. IF we assume, for the sakes of ease and of argument, that Heathrow, as the largest and busiest of the London airports, would be most difficult to relocate, then why on earth would we have not just Gatwick, but Stansted, Luton, London City, Biggin Hill, Farnborough, Southend, Northolt and the host of other 'minor' airports all within less than 50 miles?
It is not Gatwick's fault, nor is it NATS' fault, but a result of historic development of infrastructure in a completely haphazard way with no single cohesive national transport policy, which in my view makes it the governments' fault, and so by implication, as members of our wonderful but hugely inefficient and cumbersome 'democracy', OUR FAULT.
Tinkering at the edges, as has been done recently, may produce some gains and benefits, but a radical redesign to provide a 'future proof' aviation model for not just the south east, but all of the country, will require a government who are willing to put in place a strategy which will, in the long term, prove beneficial to hopefully all, but in the short term will annoy a huge number. So let's see the plans put forward after May 7th..... but don't hold your breath.
