David Hallman is a Vietnam War veteran who served as a Boeing B-52 Stratofortress navigator and radar navigator with the United States Air Force. He was born in May 1948 in Wilmington, Delaware. His father worked for IBM (International Business Machines Corporation) and was an Army Air Corps veteran. While growing up, Hallman’s family relocated several times for his father’s work. He completed high school in Glen Ellyn, Illinois and afterwards attended the Air Force Academy. He graduated in 1970 with a bachelor’s degree in engineering.

Though he initially intended to enter flight school for pilot training, Hallman could not pass the flight physical due to a childhood eye injury. Instead, he entered navigator training and received training in the Convair T-29 and Boeing B-52 Stratofortress. In 1972, he was assigned to the 77th Bomb Squadron, 28th Bomb Wing, at Ellsworth Air Force Base (South Dakota). Shortly afterwards, he was deployed to Andersen Air Force Base in Guam. He participated in Operation Arc Light, serving as navigator aboard B-52Gs during long-range bombing missions to South Vietnam. In December 1972, he participated in Operation Linebacker II against North Vietnam. After a stateside rotation in early 1973, he served his final combat tour at U-Tapao Air Base in Thailand, this time flying aboard B-52Ds. At the completion of his combat tours, he had served on approximately 68 missions and had logged over 600 hours of combat flight time.

After returning to the United States, Hallman served with Standardization Crew S-01, then earned his qualification as a radar navigator. He continued to serve with the 28th Bomb Wing at Ellsworth Air Force Base, where he participated in nuclear alert assignments. He was honorably discharged in 1975.

In his civilian life, Hallman worked briefly for IBM, then joined Sun Chemical in the graphic arts business.
