Investigation Summary
The flight was on its final leg from Manila to Saigon when Nguyen Thai Binh handed a note to a flight attendant claiming he had a bomb and demanding the flight divert to Hanoi. The captain, Eugene Vaughn, proceeded to Saigon under the guise of needing to refuel. Upon landing at Tan Son Nhut Air Base, Binh held a knife to a flight attendant's throat. During a tense standoff on the ground, Captain Vaughn and a passenger (a retired police officer) neutralized Binh. The hijacker was shot five times by the passenger and his body was thrown onto the tarmac. No explosives were found; the 'bombs' were actually lemons wrapped in foil.
Final Conclusions
The incident was a politically motivated hijacking. The threat was found to be a hoax, as the hijacker was armed only with a knife and dummy explosives. The situation ended with the death of the perpetrator and no other fatalities among the passengers or crew.
