Charles Alan Hassler died at his home in Denver on February 28, 2022, at the age of 90.  He was born to Charles H. and Dorcas (Taylor) Hassler on September 1, 1931, in Holyoke, Colorado.  Charles, better known as "Chuck," was raised on the family farm one mile south of Amherst, Colorado, along with his brothers, Paul and Neil.  Chuck attended Phillips County High School, where he served as editor of the school Annual.  He graduated with the Class of 1949.  Chuck then went to work for Convair aircraft manufacturing in San Diego, California.

In 1952, Chuck joined the Service.  He served as a combat Infantryman, with the rank of front-line Staff Sergeant in the Korean War from 1952–1953.  He later served as a military policeman for three years in Germany.

Chuck always held a great fascination with mines and mining. At one time, he spent six weeks in the Superstition Mountains of Arizona, searching for the Lost Dutchman Mine.  Chuck spent some time working for a copper mine in Arizona.  He also was an employee for American Metal Climax at its Leadville, Colorado, molybdenum mine.  Chuck returned to the Climax mines a couple of times during United Airlines lay-offs.

Chuck was also employed by Boeing Aircraft in Seattle, Washington.  He enjoyed working on the first 707 aircraft Boeing built.  Chuck was proud to sign his name on the 707 jet built specifically for President Dwight D. Eisenhower.

In 1963, Chuck was hired by United Airlines in San Francisco, California.  He was later transferred to Denver, Colorado, where he was a mechanic, a troubleshooter, and aircraft inspector.  Chuck was always ready to travel on short notice wherever needed as problems arose.

In the early seventy's, Chuck took a voluntary leave of absence.  He went to work for Lear Siegler, servicing helicopters in Viet Nam during the war.

Chuck then returned to United Airlines, retiring later after more than 30 years.

Throughout his life, Chuck greatly enjoyed the outdoors, exploring whatever location he was in.  He enjoyed camping and hiking, and other countries, learning about and living in different cultures.  Chuck was a life-long learner, always eager to acquire more world knowledge, through travel, books and people.  Chuck was always known to be a kind and caring man to others.

He is survived by his brothers Paul (Beverly) of Colorado Springs, Colorado, and Neil (Hilda) of Holyoke, Colorado, nephew Alan (Karla), nieces Debbie (Jim) Homan, Ann (Edward) Ftorski, Susan (Mike) Bennett, and Lauri Hassler, wife of Paul J, eight great-nephews and great-nieces, along with many other family members and friends, who will miss him dearly.
