Minimize Hong Kong International Airport

Hong Kong International Airport is the main airport in Hong Kong. It is colloquially known as Chek Lap Kok Airport, being built on the island of Chek Lap Kok by land reclamation, and also to distinguish it from its predecessor, the closed Kai Tak Airport. The airport opened for commercial operations in 1998, replacing Kai Tak, and is an important regional trans-shipment centre, passenger hub and gateway for destinations in Mainland China (with over 40 destinations) and the rest of Asia. HKIA also operates one of the world's largest passenger terminal buildings (the largest when opened in 1998) and operates 24 hours a day. The airport is operated by the Airport Authority Hong Kong and is the primary hub for Cathay Pacific, Dragonair, Hong Kong Airlines, Hong Kong Express Airways and Air Hong Kong (cargo). The airport is also one of the Asian-Pacific cargo hubs for UPS Airlines. It is a focus city for many airlines, including China Airlines and China Eastern Airlines, which serves 18 flights to Hong Kong per day (one direction) from 15 cities. Virgin Atlantic, United and Air India use Hong Kong as a stopover point for flights respectively from London to Sydney, from Tokyo to Singapore and Ho Chi Minh City as well as from India to Osaka and Seoul. HKIA is an important contributor to the Hong Kong economy, employing approximately 60,000 people. About 90 airlines operate flights from the airport to over 150 cities across the globe. In 2011 HKIA handled 53,314,213 passengers, making it the 10th busiest airport worldwide by passenger traffic.It also surpassed Memphis International Airport to become the world's busiest airport by cargo traffic.

Landsat 5 and 7 animation from May 1988 to September 2000

This animation created from a series of images acquired with the Landsat 5 and 7 satellites, shows the phases of construction relative to the new airport. Starting from 1988 the animation shows the two islands where the infrastructure was realised. In 1990 the island of Chek Lap Kok is visible as the first changes for the construction of the airport. From 1992 to 2000 the images show the state of work on the island.
