Flight Into The Future
Original Broadcast: 25 October 1967
 
Smith accidentally launches the Space Pod with himself, Will and the Robot aboard. They land on a mysterious green glowing planet. They find themselves 270 years in the future, the J2 in ruins, a cenotaph to the Robot, and space archaeologists.
 
Will meets Judy's great-great-great granddaughter, who, aside from wardrobe, is the spitting image of her grand-grand-grand-grandmother. Marta portrays ther descendant with just a hint of something unworldly beneath the surface. Is it because she is of a future generation, or something else? It marks the start of a growing suspicion that something is amiss in this future.
