Some people are afraid of flying. They are worried that the plane will crash or that someone may

hijack it. A person who hijacks a plane usually says he will blow up the plane if he does not get money.

Sometimes hijackers do not want money, however. They want other things. They some -times want their

friends let out of jail or to go to another country.

The first hijacking happened on 16 June 1948 on a plane traveling from Macau to Hong Kong. Some

men with guns told the pilot they wanted, money. The pilot fought them, but the hijackers shot him. The

plane crashed into the sea, and nearly everyone in it died. Only one man lived. His name was Wong-yu

Man. When the police brought the plane out of the sea, they looked at it very carefully and found bullet

holes in the walls of the plane. They knew then that there had been a hijack.

A policeman sat near Wong-yu Man's bed in the hospital. Before long Wong-yu started to talk in his

sleep. "Where are my men?" he said. "Are they all right? Did they get the money?" The policeman wrote

everything down. He knew Wong-yu's words meant something. He thought Wong-yu was one of the

hijackers. He was right. When Wong-yu came out of hospital, he went to jail for a long time.
