On December 25, 1967, Capt. Terry T. Koonce was the pilot of a T28 on a mission in Laos. Koonce was a relatively experienced pilot, having graduated from the Air Force Academy in 1961 and gone into flight training following graduation. The Christmas Day mission took Koonce over Khammouane Province, Laos near the Ban Karai pass.

The Ban Karai Pass was one of several passageways through the mountainous border of Vietnam and Laos. American aircraft flying from Thailand to missions over North Vietnam flew through them regularly, and many aircraft were lost. On the Laos side of the border coursed the "Ho Chi Minh Trail", a road heavily travelled by North Vietnamese troops moving materiel and personnel to their destinations through the relative safety of neutral Laos.

Koonce was at the city of Ban Som Peng when his aircraft was hit by enemy fire and crashed. Whether Koonce was able to bail out of the aircraft is unclear, but he was declared Missing in Action. He is one of nearly 600 Americans lost in Laos during the Vietnam war.
