Blériot 135

The Blériot 135, also written Bl-135, was a French airliner of the 1920s that developed the Blériot 115 by fitting more powerful radial engines. Two were built, one of them a converted 115 and the other new, and both served with Air Union on its Paris to London route from mid-1924. Its specifications record a four-engined layout with Salmson 9Ab engines of 172 kilowatts (230 horsepower) each, a crew of two pilots and a radio operator, room for eight passengers, a wingspan of 25 metres, a gross weight of 5,300 kilograms, a maximum speed of 190 kilometres per hour and a range of 570 kilometres. A five-seat day-bomber version, the Blériot 136, was projected but not built.
