Recently completing a model of a Vickers Vanguard reminded me of its much more successful smaller brother the Viscount which i used to see flying into BHX in the late 70s and 80s. The Viscount was one of the first airliners equipped with the new turboprop engines in the early postwar period. It first flew in 1948 and despite the new engine technology was a conventional aircraft, however it was also very reliable and popular with passengers too. The new turboprop engines gave it a higher performance and smoother flight characteristics than piston engined airliners, but it was also more fuel economic than turbojet powered airliners (albeit which were faster and larger)
A total of 445 Viscounts were sold (compared to only 44 Vanguards) and they served with airlines across the world on short and medium haul routes. The last Viscounts probably flew commercially in 2007/8, not a bad service life at all considering it was designed just after the war. The Viscount below in the grainy photo was at RAF Cosford when i photographed it with my Instamatic camera!
