 GEOG: In the beta version of the game, Fort Baxter Air Base was  going to be larger, and have its own runway and communications  tower. However, they removed this from the final game, but in the  view from the other island (when you are not on the island the air  base is located) you can still see the tower. When you enter the  island, it disappears. Among fans of the series, the tower is known  as The Ghost Tower.
