This isn't mine, but I think it's clever...it came from here...

As Pete points out, the version of The Incident that we saw might in fact have slightly varied from the one described in the Swan orientation video. If so, that potentially creates a ripple affect of Island history, not world history. And in this new timeline, the Kahana never comes, the donkey wheel never gets turned, Jin never meets 1988 Danielle, she goes into the Temple, and never changes the message. But many things stay roughly the same, just in a slightly altered or delayed manner. Including Oceanic 815 crashing on the Island.

But I think it's still a different crash. Suppose the anomaly doesn't mean that Oceanic 815 lands safely in Los Angeles: it means that it crash lands on the Island, but with certain people possessing new insight into what Jacob wants them to do. Those touched by Jacob, who go through the "progress" of the past five seasons, now understand the point at which things went off the rails first time through, and are able to change things this time around. They still build their camp, but go about things in a different way.

I'm not sure I am totally sold on this variation, but it seems a better way to go than have Oceanic 815 land safely in L.A. I don't see one possible way in which that ends well for the show or the fans. The idea of them being blown through time to 2007 via some type of boom tube seems the most likely, with Jacob sending the Jack/Kate/Hurley/Sayid collection there to collect those incorrectly placed in time by Ben's turning of the donkey wheel.

But I'm kinda fascinated by the idea of Season 6 being Season 1, but an alternative version of it. The mind sorta boggles, doesn't it?
