I'm at the airport every week plane spotting. As people have said the Airport Island (Chep Lap Kok) was a small island. This was flattened and rocks and other material was dumped to form the island. The main part of the terminal is on what was Chep lap kok island.
Its hard to explain how big it is, all i can say is during Hong Kongs bad visibility you cant even see the tower from the terminal, the tower is in the centre of the airport. Haeco is at the far end. Its miles away. Not only has the airport been built but so to has the town of Tung Chung, this town is already expanding fast. The First McDonalds opens soon !!!
Bush, your a sad, sad man.
