Napalm became one of the more used weapons of the Korean War. Pilots returning from the war zone often said that they would rather have a couple of gasoline tanks full of napalm to drop than any other weapon, bombs, rockets or guns. The U.S. Air Force and Navy used napalm with great effect against all types of targets to include troops, tanks, buildings and even rail road tunnels. The fear napalm had on the enemy became obvious when North Korean troops began to surrender to aircraft flying overhead. Pilots noted they saw surviving enemy troops waving white flags on following passes after dropping napalm. The pilots radioed to ground troops and the North Koreans were captured.
