Clifford Henderson brought the faltering National Air Races to Los Angeles 
      Mines Field  in September of 1928.  He also added an Aeronautical 
      Exposition to showcase the latest in aircraft and related equipment.  The 
      1928 National Air Race was a major improvement over previous exhibitions 
      held at non spectator-friendly military air stations. 1929 would be a 
      quantum leap in quality and a much-needed public exposure of aviation in 
      general. 
      
      
      In 1929, 
      Cleveland hosted the National Air Races and Aeronautical Exposition. The 
      Cleveland Airport was the first municipally owned in the country. It was 
      large enough to host the races on the west end of the airfield without 
      interrupting normal commercial traffic at the east end.   A state- of -the 
      -art passenger terminal building had just been opened, complete with 
      beautiful landscaping. More than a dozen new  hangars and support 
      buildings were either complete or under construction.  
       
      The 
      Aeronautical Exposition was held in the new $10 million Public Hall 
      in downtown Cleveland. No less than 250 exhibits displayed $3 million in 
      aircraft, motors and accessories. Musical extravaganzas were offered each 
      day and evening.

      On the 
      day prior to the opening of the races, a very large parade was held on the 
      main street of downtown Cleveland, with no less than 100 floats, most of 
      them covered with fresh flowers.  Overhead, an armada of military and 
      civilian aircraft accompanied the parade.

      Many 
      dignitaries and movie stars were in attendance, national hero Charles 
      Lindbergh and Commander Hugo Eckner of the Graff Zeppelin, to name just 
      two. Pilot Jimmy Haizlip said "the whole of aviation was there and you 
      could have put them all in a dance hall and have half of it left over". 
      The daily schedule included other aviation attractions such as parachute 
      jumping, military demonstrations, lighter than-air craft, air derbies and 
      aerobatics demonstrations. Coupled with the Aeronautical Exposition and 
      concerts, this was a major entertainment spectacle and a much needed 
      public exposure of military and civilian aviation.

      While the 
      military dominated the previous National Air Races, this year would be 
      different.  President Walter Beech of the Travel Air Manufacturing Co. in 
      Wichita had secretly developed a low-wing monoplane with great speed 
      potential to enter in the free-for-all race.   This aircraft was tested 
      and flown to Cleveland, where Beech had arranged for a private hangar for 
      his entrants.  As soon as the plane landed, it was rolled into the hangar 
      and the doors closed. The press called it the "Mystery Ship".
      On Sept. 2nd, Doug Davis, an 
      airline pilot from Atlanta, Georgia, flying the Travel Air "Mystery Ship", 
      won event no. 26, the 50-mile free-for-all speed contest. During the race, 
      Davis cut inside one of the pylons and had to re-circle it but still 
      managed to beat both the Army's and Navy's fastest pursuit planes. Charles 
      Thompson, president of Thompson Products Company, sponsor of the event 
      personally, awarded the large cup to Doug Davis. Second place went to Lt. 
      Breen in a Army P-3A. Third place went to Roscoe Turner in a Lockheed 
      Vega.
