Andrei Nikolaevich Tupolev designed the ANT 14, a five engined airliner powered by Soviet built 358kW Bristol Jupiter radial engines: this spanned 40 m (132 ft) and could carry 42 people over 1200 km (745 miles), sufficient to fly in stages from Moscow to Vladivostock.
The one-off ANT-14 Pravda, served as flagship of the propaganda squadron. The ANT 14 was modestly successful, serv¬ing on the Moscow Berlin route and on scientific explorations in Siberia and the Arctic.
Pravda carried over 40,000 passengers before being grounded in 1941.
