I'm Leeeeeving, on a jet pla.. Errr..Helicopter.

We still don't know if Michael made it off the island..   And Hurley and
Kate are definitely not on the helicopter.     So... Do we know for sure
that the helicopter will be able to leave the island? -- Assuming it
does follow the proper compass heading?

Maybe they'll all end up on some other deserted island where Mike is
living like a wild man, or something.   That would be a neat twist..
Then the Losties would have to rely on the expertise of Miles.  (perfect
guy for the role)  ..Jon
