Superman’s grandfather Jor-El I is shown to have made a journey to Earth in an experimental space machine. His trip may have inspired his son Jor-El II to send Kal-El to Earth years later.

Synopsis:
Clark Kent receives a letter from Jeremy Bird claiming Superman visited him 60 years ago. Since Clark knows that he was not even born yet, he believes the letter is a crank, until it states the correct position of Krypton.

Clark knows that no Earth man should have that information, so he tracks down Bird and questions him. Bird explains his story further. Superman realizes that the Kryptonian Bird met was actually his grandfather.
