Did you know that in the Microprose Computer Flight Simulator "1942
The Pacific Air War" there is a secret mission? If you fly your plane
over a little green dot at the top of one of the maps, you can actually
fly over "Gilligan's Island".
As you get near, you get the mayday message, then as you coast
into the lagoon, you can see a beached boat. If you fly real low
and head for the boat, the group of castaways can be seen lined up on
the beach waving at you.
According to the "Official Strategy Guide" (by John Possidente, Prima
publishing) for "1942 The Pacific Air War", on page 431 under the
heading "Castaways" it gives the exact co-ordinates of the Island as 188
degrees 9 minutes East by 33 degrees 47 minutes North.
It suggests that you use the game's Mission Builder to put your primary
flight within the vicinity, otherwise you are in for a three hour
flight.
Hope this helps for anyone else who is curious enough to give it a try.
