Captain Bennett elected to ditch in the Gulf of Tonkin, although he knew that his cockpit area would very likely break up on impact. No pilot had ever survived an OV-10 ditching.
The OV-10 was a twin-turboprop short takeoff and landing aircraft conceived by the US Marine Corps and developed under a US Air Force, Navy and Marine Corps tri-service program. The first production OV-10A was ordered in 1966, and its initial flight took place in August 1967.
The Bronco’s missions included observation, forward air control, helicopter escort, armed reconnaissance, gunfire spotting, utility and limited ground attack. The USAF, however, acquired the Bronco primarily as a forward air control (FAC) aircraft. Adding to its versatility is a rear fuselage compartment with a capacity of 3,200 pounds of cargo, five combat-equipped troops or two litter patients and a medical attendant.
The first USAF OV-10As destined for combat arrived in Vietnam in July 1968. A total of 157 OV-10As were delivered to the USAF before production ended in April 1969.
On Jun. 29, 1972, Captain Steven L Bennett, a USAF FAC, was flying an OV-10 Bronco on an artillery adjustment mission near Quang Tri City, South Vietnam. A Marine gunfire spotter occupied the rear seat of the lightly armed reconnaissance aircraft.
According to Air Force Historical Support Division, after controlling gunfire from US naval vessels off shore and directing air strikes against enemy positions for approximately three hours, Captain Bennett received an urgent call for assistance. A small South Vietnamese unit was about to be attacked by a much larger enemy force. Without immediate help, the unit was certain to be overrun. Unfortunately, there were no friendly fighters left in the area, and supporting naval gunfire would have endangered the South Vietnamese. They were between the coast and the enemy.
Captain Bennett decided to strafe the advancing soldiers. Since they were North Vietnamese regulars, equipped with heat-seeking SA-7 surface to air missiles (SAMs), the risks in making a low-level attack were great. Captain Bennett nonetheless zoomed down and opened fire with his four small machine guns. The troops scattered and began to fall back under repeated strafing.
As the twin-boomed Bronco pulled up from its fifth attack, a missile rose up from behind and struck the plane’s left engine. The explosion set the engine on fire and knocked the left landing gear from its stowed position, leaving it hanging down. The canopies over the two airmen were pierced by fragments.
Captain Bennett veered southward to find a field for an emergency landing. As the fire in the engine continued to spread, he was urged by the pilot of an escorting OV-10 to eject. The wing was in danger of exploding. He then learned that his observer’s parachute had been shredded by fragments in the explosion.
Captain Bennett elected to ditch in the Gulf of Tonkin, although he knew that his cockpit area would very likely break up on impact. No pilot had ever survived an OV-10 ditching. As he touched down, the extended landing gear dug into the water. The Bronco spun to the left and flipped over nose down into the sea. His Marine companion managed to escape, but Captain Bennett, trapped in his smashed cockpit, sank with the plane. His body was recovered the next day.
For sacrificing his life, Captain Bennett was posthumously awarded the Medal of Honor. The decoration was presented to his widow by Vice President Gerald R. Ford Aug. 8, 1974.
