In the dark hours of June 19, 1968, deep in hostile territory, Lieutenant Clyde E. Lassen piloted his helicopter on a mission that seemed nearly impossible: to bring home two downed aviators before the enemy could capture them. What followed was one of the most daring rescues of the Vietnam War—a mission so extraordinary it earned Lassen the Medal of Honor.

Assigned as pilot and aircraft commander of a UH-2 Seasprite helicopter with Helicopter Support Squadron 7, Lassen launched after midnight, knowing little about the terrain ahead. His orders were clear but daunting: locate the stranded aviators on a steep, tree-covered hill, retrieve them under fire, and bring them safely home.

The challenge was immediate. As he approached the site, enemy fire lit up the night sky. Lassen first attempted to land in a clearing at the base of the hill, but thick undergrowth made it impossible for the survivors to reach the aircraft. Time and fuel were slipping away, yet he refused to abandon them.

With the aid of flares dropped overhead, Lassen maneuvered his helicopter into a treacherous hover between two trees near the survivors. Just as hope surged, the last flare burned out. Darkness swallowed the helicopter, which collided with a tree and dropped sharply. Lassen, displaying nerves of steel, steadied the aircraft and pulled away. Still, he would not give up.

Again he attempted the rescue, again relying on flares—and again, illumination failed. Enemy guns pressed harder, fuel ran dangerously low, and his helicopter bore the scars of damage. In that moment, Lassen made the decision that defined his mission. Fully aware he would reveal his position to hostile forces, he switched on his landing lights, becoming a target in the black night.

That final gamble worked. The aviators scrambled aboard, and Lassen pulled the damaged helicopter into the sky. The danger was not over—on the way to the coast, antiaircraft fire streaked upward—but Lassen skillfully evaded the barrage. With fuel enough for only five minutes of flight, he finally touched down aboard the USSJouett. Against all odds, everyone was alive.

The Navy described his actions as “a supreme example of courage, resourcefulness, and devotion to duty.” Lassen had faced the unthinkable—flying a single-engine helicopter, nearly out of fuel, through enemy fire and pitch-black skies—and still he chose to risk everything for his comrades. His Medal of Honor mission remains one of the most dramatic rescues in U.S. naval history.

Later, reflecting on the night, a fellow officer summed it up: “He was flying an old, single-engine helicopter. He was out there in the middle of the night for the sole purpose of rescuing the aviators. When he put on his landing lights it made him a great big target, but he was able to do the rescue”.
