Pan Am Flight 73 was a Pan American World Airways flight from Bombay, India, to New York City, United States, with scheduled stops in Karachi, Pakistan, and Frankfurt, West Germany.
On September 5, 1986, the Boeing 747-121 serving the flight was hijacked while on the ground at Karachi by four armed Palestinian terrorists of the Abu Nidal Organization. The aircraft, with 360 passengers on board, had just arrived from Bombay. A grand jury later concluded that the terrorists were planning to use the hijacked airliner to pick up Palestinian prisoners in both Cyprus and Israel.
More than twenty passengers were killed during the hijacking, including nationals from India, the United Kingdom, Italy, Pakistan, and Mexico. All hijackers were arrested and sentenced to death in Pakistan.
