Vickers Viscount

The world’s first turboprop airliner, the Vickers Viscount was one of the Pew British aircraft to make an impact on the American market. Hugely popular with passengers, it offered a distinctly more comfortable, quieter, and faster ride than its piston-engined equivalents, as well as giving travellers an excellent view from its relatively large windows.
The Viscount took time to find its market. The first of the breed, the Type 630, made its maiden flight in July 1948. Although almost
trouble-free from the outset, its 32-passenger capacity was too low to attract airline interest.
It was only after Vickers flew the protoype of the enlarged, higher-powered 53-seat Viscount 700  in 1950 that orders flooded in, first from British Europcan Airways and then from many other airline carriers,  including several in the United States. The 700 entered service in April 1953.  In the second half of the 1950s the stretched Viscount 800 series increased passenger capacity to 69.
By the 1960s turboprop airliners were going out of fashion, upstaged by the glamour of jets even on shorter routes, where they remained more efficient. Production ended in 1964, by which time 445 had been built.
