LANGLEY AIR FORCE BASE, Va. -- Bob Gaylor, fifth Chief Master Sgt. of the Air Force, stands in front of a rough sketch drawn by an individual from the 94th Fighter Squadron here July 23. The sketch is going to be a hand-painted rendering of our Air Force heritage. Chief Gaylor is touring Langley, and speaking to Airmen about the Air Force and how to keep your self motivated.
