The Gatwick campaigners (NoGaR) have vowed to renew their efforts to stop any future plans for a second runway at Gatwick:
BBC NEWS | England | Sussex | Vow to fight extra Gatwick runway
Clearly they are aware that the deal between BAA and West Sussex County will be null and void once the airport is sold, which would leave the future owners open to pitch Gatwick as a viable alternative to Heathrow, which could lead to a second runway.
So the whole farce goes back to square one.
