In its extensive holdings of documents related to aeronautics, the National Archives keeps in trust records that begin with those of the National Advisory Committee that was formed in 1915 to study problems in flight and conduct research in aeronautics. NASA records are also held at the National Archives, as is the Wright brothers’ patent for their flying machine.
