Having envisioned life as a fighter pilot following World War II, Scowcroft completed his pilot training in October 1948 following his commissioning as an Air Force Second Lieutenant in 1947 and received his Air Force Command Pilot Wings. However, on January 6, 1949, while on flight training with North American P-51 Mustang, his P-51 Mustang aircraft experienced engine trouble after taking-off from Grenier Army Airfield, causing the plane to crash-land. Although his injuries were not critical, Scowcroft assumed that he would never fly again and considered another career within the Air Force. He served in a variety of operational and administrative positions from 1948 to 1953. In the course of his military career, he held positions at the Joint Chiefs of Staff, headquarters of the United States Air Force, and the Office of the Assistant Secretary of Defense for International Security Affairs. His other assignments included: faculty positions at the United States Air Force Academy and the United States Military Academy, and Assistant Air Attaché in the American Embassy in Belgrade, Yugoslavia.
