Island location
I unfortunately didn’t start watching Lost until season 3, so my information is a little spotty.
My thoughts are where the actual island is. We know the plane left Australia, and crashed 1000 miles from Fiji, so this would most likely put the crash in the southern hemisphere. In the episode with Juliet’s history, she left from Ore which is in the northern hemisphere. I know she was drugged, but that’s an awful long trip for the amount of drugs she had swallowed even by plane. I don’t remember seeing intravenous drugs when she got off the sub. So to bring this all into one point, has the location been explained? Maybe they are able to teleport, as odd as that sounds they do have a big smoke security system on the island, things to a certain point, and then ship them in via sub. I’m sure it’s an odd theory, but this is an odd island.
