F-82A Twin Mustang on display at the US Air Force Museum in Dayton, Ohio. This front view shows the connection between the two Mustang fuselages. In addition, if you look carefully, you can see that the two propellers are mirror images of each other. This is because the engines and props, while being nearly identical, turn in opposite directions. This opposite rotation cancels out the torque produced by having large amounts of metal spinning very fast.
