1. Papers, Engineering Drawings, and Articles, 1929-2009 (3.25 cubic feet). This series of the Ralph Johnson papers has a strong focus on the unique air safety contributions he made to aviation and aeronautical engineering. Included are Johnson’s engineering drawings, papers he authored, various articles, biographical information, clippings, certificates, correspondence, manuals, memorandums, memoirs, “reading files,” records, reports, and transcripts.
Highlights of the papers are Johnson’s reports on “The National Army Air Maneuvers of 1931;” “Exposure – The Key to Flight Safety,” which includes Johnson’s designs; all weather and landing techniques; ice accumulation studies/de-ice issues; and papers authored by Johnson and published in Air Transport.
Some of the material focuses on the latter part of Johnson’s career, as he was recognized for his pioneering aviation feats. The memoirs give the reader a look into the life of Ralph S. Johnson, as he saw it during this unique time in early aviation history. Most of the biographical information was collected and written by the authors for awards for which Johnson had been nominated.
