On June 8, 1959, in a move a postal official heralded as "of historic significance to the peoples of the entire world," the Navy submarine U.S.S. Barbero fired a guided missile carrying 3,000 letters at the Naval Auxiliary Air Station in Mayport, Florida. "Before man reaches the moon," the official was quoted as saying, "mail will be delivered within hours from New York to California, to Britain, to India or Australia by guided missiles." History proved differently, but this experiment with missile mail exemplifies the pioneering spirit of the Post Office Department when it came to developing faster, better ways of moving the mail…. however, they don’t mention if the 3,000 letters were ever delivered.
