Despite its performance, the XB35 was too far ahead of its time. The aircraft did not exhibit good handling qualities and thus was not a good bombing platform. It needed the type of computer-based, multiply-redundant autopilot that is standard equipment on today’s aircraft.
An aircraft is a machine that is able to fly by gaining support from the air. It counters the force of gravity by using either static lift or by using the dynamic lift of an airfoil, or in a few cases the downward thrust from jet engines. Common examples of aircraft include airplanes, helicopters, airships (including blimps), gliders, and hot air balloons.
