"Doolittle" refers to the Doolittle Raid, a significant military operation during World War II. On April 18, 1942, a group of 16 U.S. Army Air Forces bombers, led by Lieutenant Colonel James Doolittle, conducted a surprise attack on Tokyo and other locations in Japan. This mission aimed to boost American morale and demonstrate that Japan was vulnerable to American air strikes. The raid was notable for its daring nature, as the bombers launched from the aircraft carrier USS Hornet. Although the damage caused was limited, the operation had a profound psychological impact on both the United States and Japan, marking a turning point in the war.
