Leo Hukill, 79, who retired as a master sergeant from the Air Force in 1952, died Friday at Southern Maryland Hospital Center in Clinton. He had a heart ailment.

During World War II, he was a commissioned officer for four years, rising to the rank of major and seeing duty in the European theater. He was mustered out at the end of the war and reenlisted as a master sergeant.

At the time of his retirement, he had served longer at Bolling Air Force Base than any other airman. He had enlisted in the aviation section of the Army Signal Corps in 1919, and arrived at Bolling 17 days later.He was stationed there and in the Philippines until the outbreak of World War II.

Mr. Hukill, who was called major by his family and friends, was crew chief on one of the first Army transcontinental flights, which took place in 1922 aboard the DHB4 plane.

When he retired in 1952, he was a line chief of the 1102nd Maintenance Squadron, which was responsible for most of Bolling's aircraft maintenance.

In July 1962, Mr. Hukill had the honor of being a passenger on the last aircraft to fly from Bolling Air Force Base.

He was born in Calhoun, Mo., and had made his home in this area since 1922.

Mr. Hukill was a licensed commercial pilot and a member of the Quiet Birdmen, an organization of Army Air Corps pilots.

He was active in the Retired Officer's Association, the Bolling Air Force Base Officer's Club and American Legion Post 259.

Survivors include his wife, Mary, of the home in Clinton; two daughters, Mary Lee Mitchka also of Clinton, and Marsha Herrity of Alexandria, and seven grandchildren.

The family suggests that expressions of sympathy be in the form of contributions to the American Heart Association.
