'Rendezvous With Yesterday' Story Code '6034' by Harold Jack Bloom and Shimon Wincelberg Story by Irwin Allen, Shimon Wincelberg and Harold Jack Bloom

1968: Senator Clark is concerned over the rising costs of Tic-Toc, the government’s top-secret project into time-travel; unsure whether to continue its funding, he asks for a demonstration, only to be informed that the project is not yet ready. However, realising that the future of the project is at stake, Doctor Tony Newman sets the controls and, before anyone can stop him, he jumps into the Time Tunnel. Thrown through time and space, he arrives on the deck of an ocean liner – and is shocked to learn that it is the the ill-fated vessel, R.M.S. Titanic. While Doctor Doug Phillips, Doctor Ann MacGregor and Doctor Raymond Swain frantically attempt to locate their colleague, Tony desperately tries to warn Captain Smith of the impending danger; but his attempts prove futile, and he is locked up under suspicion of being a spy from a rival steamship line. Having located Tony, Doug steps into the Time Tunnel; he arrives on the Titanic and is able to free his friend, and together they use the ship’s wireless radio to summon help. The Titanic hits an iceberg and its hull is ripped open; as the ship begins to sink into the icy waters, Doug and Tony help Captain Smith begin the evactuation of the passengers and crew onto the ship’s lifeboats. Back at Tic-Toc, Anne and Swain manage to lock onto the two time-travellers and try to return them to the present, just as they are both thrown overboard; Senator Clark agrees to continue the project's funding until the two scientists are recovered. Tony arrives in the desert outside the project, only to find he is ten years in the past; but before he can be arrested as an enemy spy by the project’s guards, Tony is thrown once more through time - joining Doug in the far distant past, where they come face to face with a hungry dinosaur…

Cliff-hanger: Doug and Tony materialise aboard a rocketship - and realise that it is about to launch into space…
