When Radio announcer reports that the Missile take off is a perfect launch...Mr Howell remarkes "IT WOULD BE"

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 intimate a giant spider-Gillgian again breaks the mirror!}
