Description:As a result of the massive surprise Japanese bombing attack at Pearl Harbor on the morning of 7 December 1941. the United States of America entered the Second World War. Although the distant rumblings of war had been heard months earlier, the U.S. military was not fully prepared for combat on a worldwide scale. Our military aircraft were relatively few in numbers and consisted of trainers, transports, scouts, fighters and bombers. Many of these were obsolete when compared to the performance ot the Mitsubishi Zero that formed the backbone of the Japanese Empires aerial assault.
