Currently occupied only by a small military squad, the Swan Islands are located approximately 90 miles off the coast of Honduras.
It was used by the USA during the Cuban Missile Crises as a radio hub to send propaganda to Cuba.
It is said to be one of the most beautiful Islands in the world and there are plans for turning this into tax free retirement resort island. However this could have a negative impact on the mystery cow. The soldiers that occupy the island used to have a herd of cattle that eventually died out but there are signs that one cow and its calf still remain on the Island. If you walk to the opposite side of the island from the base you can see fresh tracks every morning but nobody has ever had a clear sighting of the cow.
