A new report (how many of these do we really need?) states that a third runway at Heathrow is "the obvious solution". Why so?
A large swath of West London will disappear to make room for the expansion, the existing airport is hardly a paragon of efficiency, the operator BAA fails to impress at every turn,
Heathrow is well-positioned to capture a lot of traffic from the west side of London where more people live (I include more than just the Home Counties in this calculation), it is adjacent to two motorways, there is a rail link and eventually T5 will be considered an asset.
So, there you have it. Well, actually, you don't, because the overriding factor for expanding Heathrow is undoubtedly the ability for BAA to open an even larger shopping experience for its harassed, oppressed and vilified travelers.
UK airports are shopping malls with runways.
