Auburn, Alabama — Major John “Alex” Klinner, a 33-year-old officer in the United States Air Force, is being remembered by family, friends and fellow service members after he was killed in a military aircraft crash in western Iraq on March 12, 2026.
The Pentagon confirmed that Maj. John A. Klinner was among the six airmen who died when a KC-135 Stratotanker refueling aircraft went down during operations connected to Operation Epic Fury.
The crash occurred while the aircraft was flying in friendly airspace, and military officials said the incident was not caused by hostile fire. The cause of the crash remains under investigation.
Klinner had served in the U.S. Air Force for eight years and held a leadership role within the 99th Air Refueling Squadron, which operates under the 6th Air Refueling Wing at MacDill Air Force Base in Tampa, Florida, with units also based at Sumpter Smith Joint National Guard Base in Birmingham, Alabama.
As a chief of standardization and evaluation, he was responsible for overseeing flight training and operational readiness for dozens of aircrew members.
Beyond his military service, those closest to him describe Alex Klinner as a dedicated husband, a loving father and a person who consistently placed the needs of others before his own.
Klinner is survived by his wife, Libby Klinner, and their three young children — a two-and-a-half-year-old child and seven-month-old twins.
His family had recently moved into a new home and were preparing for the next chapter of their lives before the devastating news arrived.
In a message shared publicly, Libby Klinner described the profound impact of her husband’s loss.
“On March 12, our world shattered,” Libby Klinner wrote while remembering the moment she learned about the crash.
She described her husband as her best friend and said the loss is especially heartbreaking for their children, who will grow up without knowing their father personally.
Family members say Alex Klinner was known for his kindness, humor and willingness to help others without hesitation.
According to those who served with him, he embodied the qualities of a servant leader, someone who quietly supported those around him while remaining deeply committed to his mission.
A graduate of Auburn University, Klinner entered the Air Force through the Air Force ROTC program before building a career in aviation and aerial refueling operations.
Throughout his service, he participated in multiple deployments supporting operations in Europe and the Middle East.
Following his death, relatives and friends have rallied around the family. Sarah Rose Harrill, Klinner’s sister-in-law, organized a fundraising campaign to help support Libby Klinner and the couple’s three children as they navigate life after the loss.
Military leaders and public officials across the United States have expressed condolences for the fallen airman and the other crew members who died in the crash.
As the investigation continues into the incident that claimed the lives of Maj. John A. Klinner, Capt. Ariana G. Savino, Tech. Sgt. Ashley B. Pruitt, Capt. Seth R. Koval, Capt. Curtis J. Angst, and Tech. Sgt. Tyler H. Simmons.
Loved ones say they are focused on honoring Klinner’s legacy as a devoted father, husband and airman who dedicated his life to service.
For those who knew him best, Alex Klinner will always be remembered not only for his military career but for the love he showed his family and the positive impact he left on everyone around him.
