"The Doolittle Raid, also known as the Tokyo Raid, on April 18, 1942, was the first air raid by the United States to strike the Japanese Home Islands (specifically Honshu) during World War II. By demonstrating that Japan itself was vulnerable to American air attack, it provided a vital morale boost and opportunity for U.S. retaliation after the Japanese attack on Pearl Harbor on 7 December 1941. The raid was planned and led by Lieutenant Colonel James "Jimmy" Doolittle, U.S. Army Air Forces. Sixteen U.S. Army Air Forces B-25B Mitchell medium bombers were launched from the U.S. Navy's aircraft carrier USS Hornet deep in the Western Pacific Ocean. The plan called for them to bomb military targets in Japan, and to continue westward to land in China—landing a medium bomber on the Hornet was impossible. All the aircraft involved in the bombing were lost and 11 crewmen were either killed or captured—with three of the captured men executed by the Japanese Army in China. One of the B-25s landed in the Soviet Union at Vladivostok, where it was confiscated and its crew interned for more than a year. Thirteen entire crews, and all but one crewman of a 14th, returned either to the United States or to American forces."
