Air Vietnam Flight 706
Le Duc Tan, a ranger in the South Vietnamese army who had recently been demoted from captain to lieutenant for the theft of two cars in Da Nang, smooth-talked his way past security checkpoints.[citation needed] After taking off from Da Nang International Airport (DAD/VVDN) in South Vietnam on a regularly scheduled flight to Saigon's Tan Son Nhat International Airport (SGN/VVTS), the flight was hijacked by Tan and two accomplices, holding two grenades.The pilot told the hijackers that he had to land for fuel at Phan Rang Air Base.[1] Shortly before the plane exploded, the pilot radioed that the hijacker was pulling the pins on two grenades.[1] The aircraft overshot the base leg and initiated a left turn, during which it lost control.
