When we see the Island underwater in LA X, there is a Dharma Shark swimming around. This seems kind of strange to me, IF the island was really destroyed in 1977 and the flight is in 2004. That would make the shark atleast 27 years old. According to wikipedia, sharks live 20-30 years, so that is a pretty old shark. I am skeptical that the shrak has hung out around the island for that long. To me, this is a clue that the belief that the island sank in 1977 and "Flight X" is in 2004 is wrong. Most likely, these events occured much closer together. Does anyone else think that's possible?
