To summarize, science becomes knowledge by publication of research results. It then may become more general knowledge as writers of textbooks pick and choose what to put in their texts, and as professors and teachers then decide what to stress from those textbooks.
The Hughes H-4 Hercules (also known as the  Spruce Goose ; registration NX37602) is a prototype heavy strategic airlift military transport aircraft designed and built by the Hughes Aircraft Company.oward Hughes was called to testify before the Senate War Investigating Committee in 1947 over the use of government funds for the aircraft. During a Senate hearing on August 6, 1947 (the first of a series of appearances), Hughes said: The Hercules was a monumental undertaking.
The M/A-Com Telecommunication was sold to Hughes Aircraft Company in 1987. Hughes Aircraft was then owned by General Motors, because it had acquired it in 1985 after the death of Howard Hughes. By 1996 the Hughes Network Systems division had $220 million in revenue and 2,200 employees. In January 2004, Murdoch's group, News Corp., bought a controlling interest in Hughes Electronics for $6.5 billion, primarily for Hughes's DirecTV satellite television unit.
