Joseph Carroll (DIA)
When the U.S. Air Force was established as a separate executive department under the National Security Act of 1947, Secretary of the Air Force W. Stuart Symington, requested FBI Director J. Edgar Hoover to loan General Carroll to the services to organize a U.S. Air Force agency for investigative and counterintelligence functions. He organized and directed this new organization, the AFOSI, along the lines of the FBI rather than the U.S. Army's Criminal Investigation Command (USACIDC or CID). General Carroll was tendered a commission as a colonel, U.S. Air Force Reserve, January 12, 1948. He was ordered to active duty in the grade of brigadier general May 6, 1948, and promoted to major general August 11, 1950.
Far East Air Force (United States)
In August 1907, Brigadier General James Allen, the United States Army's Chief Signal Officer, established the Aeronautical Division as the nation's air service and oversaw the introduction of powered heavier-than-air flight as a military application. Four years later Allen recommended the establishment of an air station in the Philippines. Military aviation began there on 12 March 1912, when 1st Lt. Frank P. Lahm of the 7th Cavalry, detailed to the Division, opened the Philippine Air School on the polo field of Fort William McKinley, using a single Wright B airplane to train pilots. Ultimately attriting four of the Army's first 18 airplanes, aviation went temporarily out of business when the last plane crashed into Corregidor's San Jose Bay on 12 January 1915.
