X Marks the Spot

Synopsis
A test missile lands at the Island... Gilligan is the only one who can fit inside to disarm it! Are the castways safe or doomed?

Quotes

 * Mr. Howell: "It would be." (After the radio announcer reports that the missile take-off is a perfect launch.)

Trivia

 * The approximate location of the Island is latitude 140 by longitude 10 degrees, which is impossible because latitudes only range ±90.
 * In this episode, when the Castaways try to signal a search plane with a mirror, Gilligan breaks it when he swings off a roof via a vine. {In a later epsiode, when the Castaways try to use a mirror to intimidate a giant spider, Gilligan again breaks the mirror!}
