In 1944, a single Douglas XB-42 Mix Master flew. With dual pusher propellers, the experimental plane handled fairly well. It had all the speed of a Mosquito Fighter Bomber but more armament and greater payload. Not too much later one set a speed record by flaying from Long Beach California to Washington in 5 hours and 17 minutes. But one thing did happen to the Mix Master that would devastate it: The War Ended. And jets were on the way. A single surviving example sits in storage at the Air Force Museum at Wright Patterson, and will be displayed just as soon as they can find the wings.
