Episode 5: Wrongway Feldman

The castaways discover the first of many surprises on the island. This time it's an airplane, and a pilot. Much to their chagrin, it's a pilot who can't seem to fly straight, hence the "Wrongway".

But it's a plane, and they're marooned, so they decide to fly it. Wrongway is spooked about flying and has been secretly sabatoging the repair efforts. So he trains Gilligan (yes, Gilligan) to fly using an ingenious flight simulator made from fruits.
Wrongway finally wises up, knowing Gilligan will mess it up, crash, die, so he knocks him out and flies himself.

True to his nickname, although he manages to get to civilization, he messes up how he got there and directions to the castaways.

My question: Why, after he landed, didn't someone, anyone recognize the name Minnow, and at least do a cursory search attempt?

A weak episode, IMHO.

Note: When asked how he survived on the island, Feldman replied "With matches, magazines, and 64 bottles of Scotch."
