In 1513, Spanish explorer Ponce de Leon first set foot on Florida's east coast. The land he discovered was a geographic anomaly so distinctive that astronaut Neil Armstrong said Florida was the first shape on earth he recognized on his return from a visit to the moon 456 years later. This unique state witnessed momentous events from the 1959 arrival of the first Cuban exiles under Fidel Castro to the 1981 launch of the "Columbia," the first space shuttle.
