Sense has prevailed, with this one decision anyway.
Build an airport in an area surrounded by bird sanctuaries and prone to very thick fog in the autumn/winter (I know its not a problem for landing but it is for taxiing and parking and taking off again...collisions waiting to happen..)
What were they thinking of? Boris's vanity project I reckon.
I'm not sure why a second terminal at EGSS was not considered, there is still enough runway capacity albeit not during the morning and evening peak times, it needs some longhaul flights to take up the slow periods.
Gatwick at the moment is the best option but its "tucked away" down in Sussex and a pain for anyone north of London to get to.
IMHO they had a chance with the old Alconbury airbase a decade ago, perfect location, access from north, south, east and west (adjacent to the A1 and A14) and next to the east coast mainline railway as well! Simple to integrate into the existing airspace structure, long runway, lots of land to build a terminal, hangars, etc etc. Oh hang on though didn't John Major live a mile down the road?
