Once again, a useful piece of government-commissioned equipment has washed ashore on the Island. This time it's an Air Force jetpack, with which the Castaways hope to alert the authorities as to their location. Gilligan (Bob Denver) is elected to strap on the jetpack and fly into the stratosphere--which he does, only to be mistaken for a UFO! Walt Hazzard, former Olympic basketball star who at the time this episode was filmed was a member of the LA Lakers, shows up as an Air Force lieutenant. ~ Hal Erickson, Rovi
