I think it's possible the chopper and crew cold have taken a cosmic shortcut.
Our man Farraday Knows the short cut.What do ya'll think?

I think that Daniel knows that there is no easy way off the island, and when he told Frank to take the "exact" heading, he knew that they would have difficulty getting to the freighter. However, since Sayid is one of the 6 that gets off, I would imagine that they make it.
