Land of the Giants
Land of the Giants ran on ABC from 1968 to 1970. The story: It’s June 12th, 1983(!), and sub-orbital passenger flight 612 is making a routine trip from Los Angeles to London with three crew members and four passengers (and a dog) onboard when it encounters a strange electrical storm during the space portion of its flight, forcing it to crash-land. The occupants quickly discover that they have not landed on Earth, but rather on an inhabited Earth-like planet where everything is twelve times its normal size. We have the entire series below.
