The Brains of the Operation

In 1937, the Army Air Corps “called for a twin-engine interceptor to pursue and destroy enemy aircraft at high altitude. It also called for a maximum level-altitude flight speed of at least 360 miles per hour and the ability to reach an altitude of 20,000 feet within six minutes. These were unheard-of performance goals at that time in aviation history, and they required the design of an advanced fighter in the truest sense of that phrase.”
