At 17:00 September 4, 1992, the flight took off from Don Mueang International Airport in Bangkok en-route to Tan Son Nhat International Airport in Ho Chi Minh City. When the aircraft was about 80 miles from Ho Chi Minh City, Ly Tong, a retired South Vietnamese  fighter pilot and naturalized U.S. citizen, used a plastic knife and a clothes hanger to threaten members of the crew. Tong claimed that he had an explosive device and had a flight attendant take him to the cockpit. Tong then forced the pilot to lower the aircraft's altitude to 500 feet, reduce speed to a minimum, and enter the restricted airspace over the city. For the next thirty minutes, Tong threw sacks of leaflets out of the cockpit window calling for an insurrection against the communist government of Vietnam in order to "build an independent, free and prosperous Vietnam ." Signing himself "Commander of the Uprising Forces," Tong subsequently donned a parachute and jumped out of an emergency exit. No one on board the plane was injured and the plane was able to continue its flight, landing safely at Tan Son Nhat International Airport with a 38-minute delay. Aftermath. Tong reportedly was captured by Vietnamese soldiers in a field outside of Ho Chi Minh City two hours later. A Vietnam Airlines spokesman said that the plane was slightly damaged when a door opened "for technical reasons" in flight between Bangkok and Ho Chi Minh City but denied that a  hijacking had taken place. Hanoi's Voice of Vietnam radio network later admitted that a hijacking had taken place. On February 24, 1993, the Supreme People's Court of Ho Chi Minh City charged Tong with air piracy and sentenced him to 20 years in prison. On September 2, 1998, Vietnamese President Trần Đức Lương signed a decision to pardon and deport Ly Tong to the US. After being pardoned, Tong continued to carry out plane hijacking missions to spread leaflets calling for the overthrow of the Cuban, Chinese and North Korean governments.
