The drug plane came from Africa. The idea of it going halfway around the world all the way to the middle of the Pacific Ocean is very unlikely. Either the island is moving, one of the planes was flying a very strange detour, or there is some sort of warp.
Official websites on the net(
http://www.thehansofoundation.org/) keep referencing an island in Zanzibar or something, which is much closer to Africa, there could be some sort of connection between the two islands.
