The Messerschmitt Me 261 was a long-range reconnaissance aircraft designed in the late 1930s. It looked like an enlarged version of the Messerschmitt Bf 110. It was not put into production; just three Me 261s were built and used primarily for testing and development purposes.

The Tachikawa Ki-77 was a Japanese very long-range experimental transport and communications aircraft of World War II derived from a design commissioned by a newspaper to break the flight distance record set by a rival. It was a low-wing cabin monoplane with twin piston engines and a tailwheel undercarriage.
