Hongkong (October 25): A remote and virtually unknown island off the central northern part of Lantao has been recommended by a firm of American aviation consultants as the site of Hongkong's suggested second airport. Senior Government sources confirmed last night that Chu Lu Kok Island, situated immediately off Tung Chung Wan, Lantao, had been recommended for the $5,000 million-plus project. The land area at the island is about the same as the present 580-acre Kai Tak airport. It is about 15 miles from Victoria Harbour. Frequented mostly by picknickers and populated by a few hundred farmers in villages mainly centred around a small river to its north, the scrub-covered island will be flattened and additional land reclaimed the moment the Government gives the go-ahead. The Assistant Director of Aviation, Mr J. K. Saunders, said yesterday the consultants had ruled out the development of Kai Tak to cope with future demand. Even if it was decided to continue pumping money into it, the life of Kai Tak could be extended for no more than three or four years at most. Mr Saunders said the proposed Lantao airport would have to be ready by 1985 at the latest, by which time 15 million passengers a year are expected to pass through Hongkong. If the Chu Lu Kok proposal is accepted, Kai Tak's 580 acres would be at the Government's disposal, and its sale would bring a staggering sum of money.
