The report is in and Gatwick is in a very good position for getting it's second runway. The restrictions that would be placed onto Heathrow to allow it to comply with today's regulations mean that it would no longer be a viable operation.
Gatwick has excellent rail connections. It is connected to 125 rail stations directly, and by the end of the decade it will be closer to 200. Heathrow is connected to six.
Gatwick also wins on noise, Heathrow impacts about 800,000 people whereas Gatwick impacts only about 3% of that number — a very tiny population. That’s because it is to the south of the city in a relatively sparsely populated area.
Unlike Heathrow, a new runway at Gatwick, will not interfere with existing motorway connections or rail services: “Already, the Sevenoaks junction round to Godstone on the M25 has been made four lanes wide, and that is going to go all the way round to Reigate in the coming years. Likewise, it will be four lanes all the way to Gatwick on the M23.
Of course the final nail in Heathrow's coffin is the Prime Minister's statement when David Cameron said "No ifs, no buts, no Heathrow third runway".
