Terminal 5

Now I am generally not a fan of modern architecture, (well apart from the typically art deco skyscrapers of New York) but I must admit that Heathrow's new terminal 5 is a stunning mass of glass,light and innovative design.
Cleverly the first glimpse of the concourse when you get off the train is from the 5th floor, where suddenly you are gazing down on the vast space which seems ten times the size of your average sports stadium. Now you expect to look up at this sort of cathedral sized structure when you enter it, but looking down on everything turns the whole airport thing literally onto its head.
I spent an interesting few hours experiencing all that terminal 5 had to offer, before a comfortable flight home.
