Savoia-Marchetti S.84

The Savoia-Marchetti S.84 was an Italian twin-engined airliner developed from the three-engined Savoia-Marchetti S.73. Only the prototype was completed, and the designation was later re-used for the unrelated SM.84 medium bomber, so the two should not be confused. The prototype was specified with a crew of at least four and seating for 18 passengers, with room for about 269 kilograms of baggage and 519 kilograms of cargo and mail. It was powered by two Gnome-Rhone 14Krsd 14-cylinder air-cooled radial engines of 670 kilowatts each, giving a maximum speed of about 350 kilometres per hour, a cruise speed of 315 kilometres per hour and a range of 999 kilometres.
