Wild Journey

Wild Journey is the 24th episode of Season Two of Land of the Giants and the 50th episode overall. It aired March 8, 1970.

Plot
Steve and Dan flee from giants and encounter a strange man in their size named Thorg accompanied by his companion named Berna. Their trust and curiosity is soon overwhelmed by suspicion when Thorg demonstrates a device called an STM (space-time manipulator). The object is able to perform several feats such as fire lasers, freeze time and travel into the past. When Thorg is temporarily knocked unconscious in an encounter by a giant dog, Steve and Dan borrow the device to travel through time back to before the Spindrift's flight in 1983 and prevent the crash on the Land of the Giants. When Thorg recovers, both he and Berna quickly realizing what they are attempting and use her identical device to follow them back to 1983 and stop them. In the past, Steve and Dan try to discourage Mark, Valerie and Fitzhugh's past counterparts not to take the flight, but they just shrug them off. They also try to get Miss Collier, the flight director, to cancel the flight, but she refuses to do so unless they can provide a decent reason to do so. Meanwhile, Berna and Thorg catch up with them and unsuccessfully warn them from changing the past as it would have dire consequence, even shrinking them down to even smaller size as a warning. When Steve and Dan realize that no one is going to listen to them, they decide that their only solution is to sabotage their ship before it can be flown. Departing, Berna gives them one last warning, but Steve and Dan still believe they are doing what's right. Unfortunately, it turns out they have already set history on track. Replacing the ship they sabotaged, they receive the Spindrift to fly the passengers and re-live the crash on the Land of the Giants. On the day two years later when he would have met Berna and Thorg, Steve discovers a receipt Miss Collier had given him in the slightly altered past.
