Desmond did say that he was on a boat and was shipwrecked on the island.zach said:note, an interesting thing about that picture...
remeber, desmond was on an "around the world race" before he showed up on the island. it might have been specifiically mentioned that he was on a boat, but i don't think so... mayhaps the dude just saw the balloon and fabbed up his story in case he needed it sometime.
