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.
Formation flights along âexpress skywaysâ â the full benefits of which are highlighted by Airbusâ Smarter Skies campaign â could reduce drag and expend less energy by up to 15 per cent.

High frequency routes would allow aircraft to benefit from flying in formation like birds during cruise bringing efficiency improvements due to drag reduction and lower energy use, according to the Vision statement.
