Donald LeRoy Calp, a retired air-traffic control engineer, died of an acute pulmonary hemorrhage Jan. 17 at his Columbia home. He was 79.

Born in Manchester, he was a 1950 Sparks High School graduate. He also attended Edison Junior College in Fort Myers, Fla.

Mr. Calp served in the Air Force during the Korean War. After he left military service in 1957, he joined the Bendix Field Engineering Corp., where he worked for nearly 40 years. He traveled to Korea, Iceland, Cuba, Florida, Australia, Madagascar, Alaska and Saudi Arabia before he returned to Maryland in 1975.

Family members said he helped build an air-traffic control system that operated from a mobile unit.

He was a founder of the South Trail Volunteer Fire Department in Fort Myers, Fla.

He enjoyed golf, lawn care and driving in his 1956 Chevrolet sedan, which he bought several years ago to commemorate the type of car he drove at the time of his marriage. Mr. Calp was a sports fan and kept up on new technologies.

Memorial services will be held at 11 a.m. Jan. 28 at Harry H. Witzke's Funeral Home, 4112 Old Columbia Pike in Ellicott City.
