Who was the only U.S. Army Air Service World War I Medal of Honor recipient who lived to receive the Medal?

Captain Edward Vernon Rickenbacker (October 8, 1890 – July 23, 1973) was an American fighter ace in World War I and Medal of Honor recipient. With 26 aerial victories, he was America's most successful fighter ace in the war. He was also considered to have won the most awards for valor by an American during the war. Rickenbacker survived and went on to build Eastern Air Lines into one of the commercial giants.

Including Rickenbacker, the U.S. Army Air Service had four Medal of Honor recipients in World War I. Second Lieutenant Frank Luke, Jr., was killed in action September 29, 1918, as the second ranking ace in that war, having shot down four enemy airplanes and 16 enemy balloons.

Second Lieutenant Harold E. Goettler and Second Lieutenant Edwin R. Bleckley were a flight crew who both were killed in action October 6, 1918 when they were attempting to drop supplies to a battalion of the 77th Division, which was cut off by the enemy in the Argonne Forest. Goettler was pilot and Bleckley was observer on that mission, whose purpose was to assist the so-called "Lost Battalion."
