Now the Heathrow decision has been made can we now not just move on?
The AC Report & the issue more generally have been analysed & debated ad-nauseam. The vocal minority have a chance to launch their legal challenges and the community will have an opportunity to voice their concerns during the DfT's public consultation ahead of the NPS.
Or perhaps by continually rehashing the whys & wherefores some believe it'll change the outcome? A similar mindset to those seeking to reverse Brexit perhaps?
The AC did consider all of the UK and announced in its interim report that it found a case for expansion in the South East - not elsewhere.
The difference in the value of economic benefits is down to the DfT & AC using different indicators (eg GDP or not).
TfL & Highways Agency have vested interests in getting someone else to pay for improvements to their infrastructure they should have already made.
There's far more public transport opportunities to Heathrow than Gatwick.
Of course, that's just my opinion based on published information.
