Charles Lindbergh's transatlantic flight in 
      1927 increased interest in aviation and the Air Commerce Act of 1926 
      established a government certification program of pilots and aircraft 
      giving the industry safety and legitimacy.  
      Rearwin Airplanes 
      was founded by Raymond Andrew "Rae" Rearwin in 1928.   
       
      Employing his two sons, 
      Royce and Ken, the small company designed and built over 400 airplanes.
