GHQ Air Force was commanded by Major General Frank M. Andrews, a classmate of Westover's who had finished one place higher in class standings. Aviation advocates looking to the Royal Air Force and its independent status from the British Army and the Royal Navy, saw this "dual authority" within aviation as the primary cause many problems in unity of command, particularly since Andrews was outspoken in his advocacy of independence for the Air Corps from the Army. He and Westover clashed often over philosophical differences on this issue, Westover believed that being integrated with the rest of the Army was the priority, as had Westover with Billy Mitchell.
