Saw the plans on the Beeb the other day.
Not even starting to dig until 2022
£15-£25 Billion (for a runway!)
Complete by 2026 (i think) with a lot more of the other work (new Terminals etc) not done until 2050
. Hell half of us here may well be dead by then
Times will have moved on (again) by then. They'll probably be asking for a 4th runway before the 3rd is finished!
The shortsightedness in this country is astounding.
Time to do the sensible thing and bring back the Boris Island project.
Get the airport away from the city with fast links (10-15 mins for 10-20 miles) into the city.
