Continuity mistake: When Jack speaks to Michael and Jin, as they build the raft, and then when he walks up the beach and inquires about Sawyer's trouble with his head, the backpack that Jack carries on his back is nylon, black/green with white trim. Yet, when Sawyer asks, "Sensitivity to light, that bad?" the backpack is suddenly transformed into solid black leather, of an entirely different style. Then, in following shots it jumps back and forth. (00:16:40)
Continuity mistake: When Boone tosses the statue out of the plane, in the close-up the entire statue shatters, and the heroine bags spill out as the head flies off to the side. But in the following shot, Locke picks up a large unbroken piece - the head and torso are intact with some bags still inside, and even that piece changes in the next shot. (00:32:50)
Visible crew/equipment: When Boone climbs up the vines toward the plane, in the first wideshot there is a rather conspicuous round CG blur at Boone's left hip that moves as he moves. Then in some following wideshots the black stunt belt at Boone's waist is perfectly visible as he makes his way up. In Boone's close-ups no such aids are on his body. (00:30:35)
Chosen answer: None of the main characters died in the plane crash. Many died on the island after the crash (Jack, Charlie, Sun, Jin, Daniel, Juliet, others), some lived on the island for an apparently long time after the crash (Hurley, Ben, Bernard, Rose) but some lived lives off the island after the crash (Sawyer, Kate, Claire, Miles, Aplert, and Lapidus). Remember that Christian tells Jack that "time has no meaning here," (in Purgatory). When everyone meets at the church, they are at the end of their lives however long that may have been and will now "move on" together. They look like they did on the island because that is the way they best remember each other.

That has to be the clearest explanation of the ending I've ever read.
