The Professor determines that a manned space craft will pass over the island, and attempts to fashion a telegraph machine. When that fails, the Castaways try to spell out SOS using burning logs as a rescue signal, but Gilligan catches fire and runs into the logs, causing them to spell out SOL, the name of one of the astronauts! Blooper watch: as Gilligan is lighting the logs, you can see his pants smoking before he backs up into the flaming logs!

A U.S. Air Force jetpack washes ashore in the lagoon. After close inspection of the jetpack, the Professor determines that the tanks contain just enough fuel to carry Gilligan to Hawaii. However, that determination was made before Gilligan wasted most of the fuel while proceeding to goof-up several attempts to be discovered and rescued. While flying the jetpack near where Navy search vessels are reported to be lurking, Gilligan is so scared by a radio report of an ""Unidentified Flying Object in the area"" that he blasts higher and hides in a cloud, not realizing that the UFO the Navy ships see is actually him with the jetpack!
