My LOST theory so far: Some sort of military experiments were taking place on this island somewhere in the South Pacific. Things went wrong and they either sent out a distress call or a stay away call, whichever it was the military didn’t answer them. The scientists on the boat tried to find them and something went wrong that caused the French woman to kill several of her fellow scientists. If the airplane survivors ever make it to the black rock they’ll be exposed to the leftover radiation or whatever that causes some of the problems. If they ever get into the underground facility they’ll find answers but lots of dead bodies. I hope they line that cradle with something soft because it looked a bit splinter-y and dangerous. I LOVED Hurley’s back story.
