The show included displays from major aviation firms showing their latest aircraft. On the first day, the prototype Boeing 707, the "Dash 80", arrived at the airport on its way to becoming an exhibit at the Smithsonian. The same day, BOAC announced its first official order for five Concordes. Douglas Aircraft, Lockheed and Boeing all used the show as a sales platform for their latest designs, the DC-10, L-1011 and 747, respectively. Douglas and Lockheed had recently started deliveries, and flew in production versions of their aircraft for the show directly from the assembly line. Numerous military aircraft also arrived, including the C-5 Galaxy.
