 LeMay initially started flying supplies into Berlin, but then decided that it was a job for a logistics expert and he found that person in Lt. General William H. Tunner, who took over the operational end of the Berlin Airlift.In 1948, he returned to the U.S. to head the Strategic Air Command (SAC) at Offutt Air Force Base, replacing Gen George Kenney.When LeMay took over command of SAC, it consisted of little more than a few understaffed B-29 bombardment groups left over from World War II.
