The title really had me confused. The Air Force is only 59 years old.
United States Air Force (USAF) is the aerospace branch of the United States armed forces and one of the seven uniformed services. Formerly part of the United States Army, the USAF was formed as a separate branch of the military on September 18, 1947. The USAF is the largest and most technologically advanced modern air force in the world, with over 9,000 aircraft in service and about 352,000 men and women on active duty.

But it existed as the General Headquarters Air Force since March 1, 1935 before its creation as a separate service. There is often confusion on this point. The members were in the Army Air Corps, just as Armor types are in the Armor Corps, JAGs are in the JAG Corps, and in fact current Army aviators haven been in the Air Corps since 1987, prior then they belonged to one of the other branches. However the units they manned were part of the Army Air Force.
The old Army Air Corps came into being in 1926 the name of the Air Service was changed to the Air Corps
