Ironic, with 20/20 hindsight, the name chosen by the Vickers company for their Viscount’s sucessor. By the 1950s, Vickers was in the crest of the wave with their bestseller short/medium range turboprop airliner. The Viscount design formula still seemed to them as good as ever, so they just tried to built bigger and more modern. Put in service during the early 1960s, the Vanguard proved to be economicaly efficient assets, but found few takers. People by then only had eyes for those sleek and very noisy propless jets. Not all was wasted, the around 40 built soon got jobs in the glamourless cargo business.
Patrician looking boss, dynamic young executive and a pretty subservient secretary….the 1950s.
