Allan “Bud” Utendorf, 85, passed away peacefully on August 28, 2025, in Arlington Heights, Illinois. A man of unwavering integrity and quiet strength, Bud lived a life defined by duty, devotion, and a deep love for his family.
 Born on October 14, 1939, in Lima, Ohio, Bud grew up in a small town that helped shape his strong moral compass and enduring work ethic. From an early age, he demonstrated a commitment to excellence and service – qualities that would guide him throughout his life. He was especially proud of earning the rank of Eagle Scout, an early testament to his character and sense of responsibility.
 Bud graduated from the United States Air Force Academy in 1961and went on to serve as an Air Force pilot, flying C-124s from McChord AFB in Tacoma, Washington. His time in the military instilled in him a profound respect for discipline and honor. After completing his service, he transitioned into civilian aviation, embarking on a distinguished career as a pilot for United Airlines.
 At home, Bud was known for his hands-on approach to life. He found joy in working on projects around the house and took pride in maintaining a beautiful garden and yard. He found pleasure in simple things, and while he usually opted for conservative cars, Bud eventually indulged in one of his dreams, purchasing a classic 1956 Thunderbird. He spent hours working on it in the garage, along with everything else that needed to be repaired. He enjoyed knowing how things worked.
 Bud was a devoted husband to his beloved wife Judy until her passing in January of this year. Together they built a life centered around family values and their love for each other. He was a loving father to Mark and Cheryl and cherished every moment spent with his grandchildren, who brought him immense pride and happiness.
 He is survived by his son Mark (Janice); daughter Cheryl (Neil) Swindells; brother Don; and grandchildren Chloe, Jack, Max, and Maya. He was preceded in death by his wife Judy; parents Edward and Helen; sisters Alice McCarthy and Barb Moorhead; and brother Jim.
 Services will be private with interment at the U.S. Air Force Academy Cemetery.
 Bud’s legacy is one of steadfast commitment – to his country, his career, and most importantly, to those he loved. May his memory bring comfort to all who knew him.
