Major (later Brigadier General) O. Glenn Goodhand was prominent in expanding the World War II role of Army Aviation in the 40's. Accumulating over 500 hours of combat flying hours, Goodhand improvised unique and effective aerial tactics in each of the three European combat areas.

At Cassino, he developed night observation techniques for the adjustment of artillery over enemy territory beyond the daytime observation range. On his own initiative he conducted experimental pioneer work in flying with L-4 Cub planes, devised feasible methods of adjusting long range artillery fire at night, and personally flew night missions, often deep behind enemy lines.

At Anzio, Captain Goodhand developed a system for Corps Artillery aircraft which assured continuous target coverage, engagement by the most appropriate artillery, and early pilot warnings of hostile fighter aircraft, the latter action greatly enhancing artillery effectiveness and pilot safety.

In Southern France, Major Goodhand organized a V Corps unit of L-5 aircraft for observation ahead of advancing ground elements. This unit developed and employed original techniques for the direction of P-47 fighter-bombers on targets beyond artillery range. His organization and operation of L-5 aircraft for reconnaissance and fighter-bomber direction was of outstanding benefit to V Corps, and was unique for liaison planes at that time.

After WWII, Major Goodhand implemented a National Guard Bureau program conceived by others which re-rated Navy and Air Force pilots as Army Liaison Pilots for Army National Guard vacancies. This program later served as a primary source of Army Aviators for the Korean War.
