If some day little green people from outer space decide to visit us, (but not like in the movie "War of the Worlds"), finally they would have a place where to land their spaceships.
Gigantic Dragon Terminal as they like to call it, is huge. With capacity of 50 million passengers per year, and coverage of 1,300-square-kilometer (501 square-mile), oh yes, is the biggest one. Just for info, the building is 17% bigger than Heathrow (London) T1, T2, T3, T4, T5 (the new one) together. It has five floors in total, two are underground. It's ready for 2008 Beijing Olympics.
Generally speaking, it's sad that Government of the countries (where are going to happen some huge events, like Olympic Games or Football Cups) find all that money for constructions. Suddenly they can repair train/metro stations, put few thousands plants back in the parks. Maybe new freeways to get all that people fast between major cities etc… But until some of that events come, it’s a mission impossible. So, if you want some "upgrades" in your town, you need some event, and make it big!
