Description
In a test of a deadly new missile, called "Operation Powder Keg," the Air Force chooses an "uninhabited island" which just happens to be Gilligan's Island. When the rocket lands and does not explode, Gilligan is chosen to crawl inside to defuse it, because he is the only one that can fit inside.
