Anyone comment on last nights episode? WOW!! So Sayid is the other one of the Oceanic 6...so we KNOW Kate, Hurley, Jack and Sayid...two more remain. I didn't count BEN because he wasn't "Oceanic" and we don't even know how he got off the island, if it was even with the other 6. But Ben obviously isn't the dead guy in the coffin in last years finale. Do you think it's John Locke? [...]
While I'm not yet convinced that it would be Ben, last night's episode doesn't entirely rule him out. The Flash-forwards aren't linear. Remember, in this seasons first episode, when Jack visited Hurley he hadn't hit rock-bottom yet.
I'm thinking about growing a beard.
and
I'm never going back [to the Island]!
The events depicted in last nights episode could very well be before the events of last seasons finale. In fact I believe that Jack's is one of the climaxes in that timeline--eventually and
inevitably leading them back to the Island where the rest of either the Fifth or Sixth Season take place.
Never say never, Dude.

Wild. And what is up with that 'payload drop'

It was off by 31 minutes? How did the chopper fly when every other attempt has seen malfunction?
The Helicopter is not the only vessel to escape the Island. Ben and the Others had a submarine; this was one of the ways how they were able to recruit more people (Juliet, Tom, Mikhail(sp?) etc.). and Michael and Walt were able to leave (or so we are lead to believe) thanks to a bearing that Ben had given them. So apparently one
can escape the Island if they take a specific bearing as Daniel Faraday strongly cautioned Frank Lapidus to take the exact same as what they followed to arrive at the Island "no matter what!".
The time-dilation most likely has something to do with the "electro-magnetism, geographical unique" to the Island* and I believe it will account for things such as
why some attempts to escape have failed (Desmond's boat), there being on the Island for approx. 90 days while the actual show has spanned four years (just a wild guess), Jack's perpetual 5 o'Clock Shadow and yes, Hurley's inability to lose weight. 
*Flashback episode with Desmond in Season 2. Sorry I don't remember which.
