From the state archives description: "MIA Airport ceremony preceding the takeoff of Pan American's inaugural jet flight from MIA/SJU/LIS. The airline's Latin American Division Manager, William Raven pointed to the benefits Florida will receive from the new Mid-Atlantic route to Europe."
The aircraft in the background was Clipper America, a B707-121 that inaugurated the first scheduled passenger jet flight by an American airline and trans-Atlantic jet service on October 26, 1958 with Pan Am Flight 114 on a New York - Gander - Paris routing. This B707 served Pan Am from 1958 to 1974 and was renamed Clipper Mayflower in later years.
