William Donald “Don” Eastman Jr. was a Port Arthur native, test pilot, engineer, and decorated United States Air Force officer whose career spanned military aviation, flight testing, combat rescue operations, and aircraft development. Born in Port Arthur, Texas, in 1932, Eastman graduated from Thomas Jefferson High School before earning a Bachelor of Science in Mechanical Engineering from Texas Tech University and a Master of Science in Aeronautical Engineering from the University of Arizona. He later graduated from the U.S. Air Force Aerospace Research Test Pilot School. Over the course of his flying career, he logged more than 8,000 flight hours and became qualified in 59 different aircraft. He retired from the Air Force as a Lieutenant Colonel.

​

Eastman achieved several aviation firsts during his career. On December 15, 1965, he became the first pilot in history to conduct an aerial refueling of a helicopter, a flight that earned him the Primus Award and the Air Medal. He completed 660 helicopter aerial refuelings, including more than 90 at night and under instrument flight conditions. The procedures developed during these tests became the foundation for long-range special operations helicopter missions and continue to be used by military forces today.

​

He was the only U.S. Air Force pilot to fly every major category of Air Force aircraft, including fighters, helicopters, bombers, transports, trainers, VTOL aircraft, autogyros, amphibious aircraft, ski-equipped aircraft, and even a NASA hovercraft. During his years as a test pilot, he routinely flew multiple aircraft types in a single day and was recognized as the first civilian test pilot hired by the U.S. Air Force.

​

Eastman also played a significant role in Alaska aviation history. In 1956, he completed the first helicopter flight to Alaska’s western coast during winter conditions. That same year, he rescued a severely burned Inuit child from Little Diomede Island in the Bering Sea and conducted the first helicopter rescue of an injured climber on Mount McKinley (Denali) at approximately 9,000 feet, above the normal operating ceiling of his helicopter.

​

During the Vietnam War, Eastman participated in combat search-and-rescue missions in North Vietnam and Laos. He was credited with rescuing more downed aircrew members than any other Air Force pilot in that theater and received the Silver Star, six Distinguished Flying Crosses, and seventeen Air Medals for heroism.

​

After retiring from military service, Eastman spent 21 years as a civilian engineer and supervisor with the Air Force, eventually serving as Director for Test, Deployment and Training Systems for the C-17 program. He also influenced the development of the C-17 and B-2 aircraft by advocating for the use of a fighter-style control stick, a design feature ultimately adopted in both aircraft.
