where were the castaways going when they were shipwrecked
The Castaways on Gilligan's Island During the attempt to fly back to Hawaii, however, the plane has engine trouble. The Professor orders Gilligan to jettison some weight, and in doing so, Gilligan falls out and has to parachute down to the island. The castaways elect to return for Gilligan, although the Professor warns takeoff will be impossible again. Right after landing, the engine falls off, and the Skipper remarks it would have been certain death had that happened while airborne. Gilligan inadvertedly saved the castaways again, and the group says they should look for him. They soon find him stuck in a tree, but now they are dismayed because the plane was their last hope of rescue. Their despair is quickly dispelled when a U.S. Navy captain appears saying that their plane was detected on radar long enough for them to follow it to the island. The castaways are once again returned to civilization and to ensure that Gilligan's Island gets charted, the U.S. government pinpoints the location of the island to prevent future castaway incidents.
