The Spindrift, a commercial spaceship on a flight from New York City 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. Written by Marty McKee
