Land of the Giants ratings (TV show, 1968-1970)

The Spindrift, a sub-oribital spaceship on a flight from Los Angeles to London, became lost when it passed through a strange cloud in the ship's orbit around Earth. It landed on an alternate Earth-type planet, where the inhabitants were roughly twelve times the size of the Spindrift's passengers. Our heroes include the ship's captain (Steve Burton), co-pilot (Dan) and stewardess (Betty); an arrogant engineer (Mark); a sexy jet-setter (Valerie); a young boy (Barry) and his dog Chipper; and a mysterious rogue known as Commander Fitzhugh. Together they battle the planet's totalitarian government, try to avoid capture, and attempt to repair the Spindrift so they can get back home.
