Message: <blockquote data-quote="Schneiderman" data-source="post: 301603" data-attributes="member: 9386">This thread really should be moved to Theoretical and Speculative, as a quick reading of the article in Flight would make clear.Saben, Hart and Partners (Group) were an engineering consultancy based in London but with numerous subsidiary companies located throughout the country. I can find no record of the formation of the parent company, or of who Saben and Hart were, but in 1956 it had come close to being wound up. However they kept going and launched an aircraft subsidiary in Bournemouth, employing a director recruited from Airspeed and P.W.Parish as chief designer. I do not know anything about Parish’s previous employment.  The two flying boats in the article were the work of R.B.Cullum and I can find not information on his previous employment either. The two flying boats are purely speculative. The freighter was an idea based on the suggestion that an aircraft for the bulk carriage of freight may be required by the late 1960s or early 1970s. It was to be powered by turbo-props of a size that was greater than any then under development. There is no indication of the expected market for the jet-powered passenger carrier. It is worth noting that neither aircraft was to be fitted with windows, to simplify construction, and that both would have a structure constructed using dimpled alloy sheeting developed by the German company Callotan.  There is no connection whatsoever with the Saro Princess, for which a specification had been issued ten years earlier, nor, as far as can be seen, with the Saro P192 project drawn up in association with the shipping line P&OBoth designs were little more than sketches and no wind tunnel or water tank evaluation had taken place. It was estimated that six men working for 18 months would be required to bring the designs up to a standard where they could be presented as true projects to potential customers and aircraft constructors. All in all they were just ideas intended to raise interest in the press to promote the company, which they did. However no one was in interested financing any further work, which is hardly surprising.The various Saben Hart and Partners companies began to be wound up through 1958 to 1961. The parent company, at least on paper, managed to continue until 1972Done, thank you !</blockquote>
