I hear you Os. It is strange that the Others know nothing of what caused the anamoly. Perhaps none of them had ever been inside the Swan, perhaps kelvin wasn't lying like i thought him to be. I should have realized that because he was trying to escape on a sailboat that he isn't an Other, they know you can't go out that way.
The Others may have seen the swan on camera, but if you didn't have a map of it's location, you may never be able to find it. So, if the Others were never in the swan, then they wouldn't know about the magnetic thingy (scientific term, look it up) that was in the middle of the place

Is that where you were going ossie?
