Here is some unique engineering, turning a 307 into a boat. When it was introduced it is the first high-altitude commercial and first four-engine airliner in scheduled domestic service. And it already had 500 flight hours. Unfortunately when hurricane damaged it in 1964 it was never flown again. In 1974, wing and the tail were taken off and the fuselage was made into a yacht. The “plane-boat” features twin V-8 inboards incorporating the original aircraft cockpit controls that were used to fly the plane, propelling the vessel over 20 mph The plane boat can be found, seen and transported by in Miami.
