Quote: "There are alternatives..Such as expanding another London Airport.."
No, expanding another London airport will not work, Ernest Lanc's, the problem is lack of hub capacity, that is why it has to be Heathrow.
There is plenty of capacity at other UK airports, except at Gatwick at peak times, and that would be sorted by adequate capacity at Heathrow.
Quote: "In truth Heathrow is the crown jewel of British airports and should be expanded by right.
it is the hub we all know, also the hub that foreigners know - an airport on stilts is not the answer."
Exactly right, and 70,000,000 pax/year cannot be wrong!
