In Episode "X Marks the Spot" 1/18 - the Airforce says they are bombing
10 Latitude and 140 Longitude +- Gilligan's Island Location

and if you locate that it's about 500 miles South East of Hawaii

Check it out

btw - there are NO islands on the map there (an Uncharted Island) (OK)
- but there is Deep Water LOL (Not OK)

I guess that's why they called it uncharted. I'm sure Sherwood Schwartz just made up an island there for the purposes of the show! :lol:

cool

18. The location of the island is 250 miles SE of Hawaii. Probably.

Just where is the island exactly? Three somewhat specific locations are given throughout the three seasons. In "'X' Marks the Spot," the island's position is said to be approximately 140º latitude by 10º longitude. (Which are impossible coordinates.) Later, in the episode "Big Man on a Little Stick," their position is stated as approximately 110º longitude by 10º latitude. (Assuming that to be negative 110º, that would put the island a ways off Mexico's Pacific coast. Finally, in "It's a Bird, It's a Plane," the U.S. Navy spots Gilligan flying over the island in a jet pack. They give the location as 250 miles south of Hawaii. So, 10º latitude, -140º longitude would make the most sense for that location.
