Miss Macao was a Catalina seaplane, owned by Cathay Pacific and operated by a subsidiary. On 1948-07-16 she became the victim of the first hjiacking of a commercial aircraft. Piracy for robbery and ransom was the motive.
The Miss Macao was on a routine flight from Macau to Hong Kong. She was hijacked a few minutes after take off by four men, three armed with guns, one of whom demanded that the pilot surrender the controls. The pilot, Dale Warren Cramer, refused and the co-pilot attacked one of the intruders with a flag-post rod. In the confusion, Cramer was shot dead, and collapsed onto the flight controls. The plane went into an uncontrolled dive and crashed into the sea. Twenty-five of the twenty-six people aboard died in the crash. The sole survivor later confessed to being one of the hijackers.
The lone survivor, Huang Yu, was brought to court by the Macau police, but the Macau court suggested that the prosecution should be brought in Hong Kong instead, since the plane was registered in Hong Kong and most of the passengers were from there. However, the British colonial government in Hong Kong stated that the incident happened over Chinese territory in which the British have no jurisdiction. Since no state claimed authority to try him, Huang was released without trial from Macau prison on June 11, 1951, and was then deported to China.
