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 aircraft's two galleys can provide up to 100 meals at a time. The decision to procure the VC-25 was made during the Presidency of Ronald Reagan. The first VC-25A, tail number 28000, flew as Air Force One for the first time on September 6, 1990 and transported President George H.W. Bush. A second VC-25A, tail number 29000, transported Presidents Clinton, Carter and Bush to Israel to attend the funeral of Prime Minister Yitzhak Rabin in 1995.
