This is the second in a series of research studies-historical works that were not published for various reasons. Yet, the material contained therein was deemed to be of enduring value to Air Force members and scholars. These works were minimally edited and printed in a limited edition to reach a small audience that may find them useful. We invite readers to provide feedback to the Air Force History and Museums Program. Dr. Theodore Joseph Crackel, completed this history in 1993, under contract to the Military Airlift Command History Office. Contract management was under the purview of the Center for Air Force History (now the Air Force History Support Office). MAC historian Dr. John Leland researched and wrote Chapter IX, "CRAF in Operation Desert Shield." Rooted in the late 1930s, the CRAF story revolved about two points: the military requirements and the economics of civil air transportation. Subsequently, the CRAF concept crept along for more than fifty years with little to show for the effort, except for a series of agreements and planning documents. The tortured route of defining and redefining of the concept forms the nucleus of the this history. Unremarkable as it appears, the process of coordination with other governmental agencies, the Congress, aviation organizations, and individual airlines was both necessary and unavoidable; there are lessons to be learned from this experience. Although this story appears terribly short on action, it is worth studying to understand how, when, and why the concept failed and finally succeeded. The payoff came during the Persian Gulf War, over the period from August 1990 until January 1991, when the CRAF flew in support of Operation Desert Shield. The CRAF provided the "greatest airlift in history," eclipsing in some aspects even the 1948-1949 Berlin Airlift. The statistics were staggering: during those 165 days the CRAF transported some 400,000 troops and 355,000 tons of cargo from the U.S. east coast to the Arabian Peninsula, an average distance of 7,000 miles. By May 1991 CRAF aircraft had transported 60 percent of the troops and 25 percent of the cargo.
