In Memoriam: Lt. Col. Mark Thomas Diebolt

Plattsburg, NY – 12/16/1932
Austin, Texas – 10/07/2023

It is with great sadness that we announce the passing of Lt. Col. Mark T. Diebolt, an extraordinary man whose life was a testament to values, courage, and the unwavering pursuit of excellence.

Born in Plattsburg NY, Mark left an indelible mark on the world. He lived a life of passion, integrity, and honor and dedicated himself to love of country and fighting Communism.

As a child in the 1940s, Mark was crushed by a tractor and was confined to a full body cast for months. He later told stories of cutting ice from Lake Champlain and hauling the blocks into the ice house. His father was a professor who taught economics at NYU and took the family to post-WWII Japan to help reconstruct the country through the Marshall Plan.

An accomplished athlete, he played almost every sport, including football, when helmets were made of leather. As a young adult, Mark continued his journey, attending Colgate University, where he honed his intellect and immersed himself in the study of classical philosophy. He was a New York State Golden Gloves boxer in the welterweight division and displayed tenacity and prowess, not only in the ring, but later as a fighter pilot, earning respect and admiration from his peers.

After graduating from Colgate University in 1955, Mark joined the U.S. Air Force, embarking on a career that would see him through some of the most critical moments in history. His aerial skills were unmatched, and he served as an Air Operations Officer and a Tactical Fighter Pilot during the Cold War leading up to and including the Vietnam War. His dedication to duty and exceptional flying abilities earned him a legendary status among his fellow aviators. He also stood ready on nuclear alert, fifteen days a month in Okinawa, Japan from 1959-1962 before later serving in the Vietnam War.

During the Vietnam War, he was in charge of the largest Forward Air Control Base at Long Tiên, ultimately completing three tours in the war-torn country. As a pilot with the 559th TFS (Tactical Fighter Squadron), part of the 12th Fighter Wing (Billy Goats), he flew more than 800 hours of combat missions from Cam Ranh Bay providing close air support, and also flying between 750-1000 combat hours hitting targets along the protected Ho Chi Minh trail in Laos. His list of proficiency with aircraft included, but was not limited to: A-1 (A,D6), F-4 (B,C,J), O1 (E,F), U-17, T28B, T33, T-34A, T39, F86F, F5E, RF5A, F5B, F100 (C,D,F).

But most important to him, it was in Cam Ranh Bay in 1969 that he met his second wife Jean Anne Youngstrom, a combat nurse in Vietnam, and the love of his life.

While serving in Vietnam, Mark was soon attached to the CIA to support the Lao Hmong guerrilla army with a number of other exceptional pilots known as the Ravens. Most of those missions were declassified in the late 1980s and these warriors, unlike any today, are immortalized in two books, The Laotian Fragments and The Ravens: Pilots of the Secret War in Laos, cementing their legacy as a true heroes.

Later in 1974, he was assigned the role of Military Attaché to the Shah of Iran, where he trained the Persian Air Force and introduced electricity to remote mountain villages in the region.

Back in Texas, when asked what medals he earned in combat, he often said, “Every time they nominated me for a medal, I told them to give it to that guy or this guy, there are plenty of men who flew more hours and deserved it more than I did.” Nevertheless, among his many medals earned in combat, he was awarded not one but two Distinguished Flying Crosses (the highest medal for extraordinary aerial achievement), and he was the first ever member of the U.S. Air Force to receive a Navy Commendation Medal. He loved flying with the U.S. Marines!

Away from the cockpit, Col. Diebolt had a passion for politics, authors such as Lawrence Durrell, the French language, the timeless melodies of Edith Piaf, all sports that interested his children, and collecting firearms. His appreciation for culture and art reflected the depth of his character and the philosophical underpinnings that drove him to excellence while fighting for liberty. Mark was not only a man of action but also a father who demanded excellence from his children in academics and sports, instilling in them the values of discipline and hard work.

Col. Mark Diebolt leaves behind a legacy of courage, honor, and an unyielding commitment to duty and integrity. As we mourn his passing, let us remember and celebrate a life fully-lived, a life that was built on selfless dedication to others, one that not only touched the skies but went further, leaving an indelible mark on those who knew, and loved him.

He is survived by his wife of fifty-two years, Col. Jean Y. Diebolt; children Mark Diebolt JD, [Melinda Diebolt], Amy Diebolt Kristofitz [Brian Kristofitz], Karen Diebolt JD, [Bob Samuelson], Alison Diebolt Linton [Tom Linton], Stephen Diebolt, Brienne Diebolt-Brown [Karl Brown PhD], Erik Diebolt DO; brother Craig Diebolt; and 14 grandchildren.
