Exodus (2) - S1-E24
Continuity mistake: In the first shot of Locke sitting in the wheelchair, in the airport lounge, he sits alone directly in front of the long rows of chairs. However, in the next overhead shot, the airline steward is at Locke's side as he sits near the large windows, nowhere near the chairs. (01:03:15)
Exodus (2) - S1-E24
Continuity mistake: In the Oceanic Int'l departure lounge, Locke sits in his wheelchair near the large window, with the doomed plane in the distance. The attendant's desk is on the left, but the black lounge chairs, which are normally situated toward the center of the lounge, are gone in this shot; the chairs at the end of each row should be visible at this angle. These chairs are also seen when Hurley crashes the scooter into them. (01:03:15)

Exodus (2) - S1-E24
Continuity mistake: When Sayid and Charlie find Danielle and Aaron, the baby is wrapped in Danielle's sweater. The sweater jumps on and off Aaron's face, etc., depending on various camera angles. (01:07:30)
Exodus (2) - S1-E24
Visible crew/equipment: As the "rescue" boat nears the raft with Jin, Sawyer, Michael and Walt, it has a spotlight shining on the four aboard the raft. That spotlight is the only light source in the area, yet the boat is bathed in bright light from behind, which also reflects in the boat's pole. (01:12:00)

Exodus (2) - S1-E24
Continuity mistake: At the airport, when Hurley rushes to make his flight the sweat stain on his t-shirt changes drastically between shots, so by the time he boards the plane - it goes from drenched to much less wet.
Exodus (2) - S1-E24
Factual error: Hurley arrives at the departure gate and calls to the woman to wait and let him board. As he goes through the gate, a sign with the word 'authorized' is visible to the left. This scene supposedly takes place in an Australian airport, but this is the American spelling - in Australia, the word is spelled 'authorised'.
Exodus (2) - S1-E24
Continuity mistake: In 'House of the Rising Sun' (01-06) Charlie tells Locke the man at Sydney Airport made him check his guitar. However, in this episode, we see Charlie squeezing his guitar into a luggage compartment onboard the plane.
Exodus (2) - S1-E24
Factual error: In the flashback that reveals the phone call Michael makes to his mother about Walt, Walt is seen playing a Nintendo Gameboy Advance SP before the phone call. After the phone call, when Walt stands behind Michael, Walt tells Michael that he needs new batteries. However, The Gameboy Advance SP works with a rechargeable battery which cannot be replaced with common batteries.

Man of Science, Man of Faith - S2-E1
Continuity mistake: At the start we see Desmond in the hatch. When the explosion goes off he gears up and runs over to a machine where he turns the music off. The shot of the shelf is a flipped shot. (00:02:28)

Man of Science, Man of Faith - S2-E1
Revealing mistake: When Michael and Sawyer are on the raft and they hear the knocking on the raft, you can see the cable holding the raft in place descending to the floor. (00:10:30)
Man of Science, Man of Faith - S2-E1
Plot hole: Sawyer pulls the bullet out with his bare hands, we are led to believe, through the cut the bullet made. When you are shot, the flesh immediately seals up, meaning you would need a knife or something like that to get it out. Sawyer only had the gun, as he could not have hidden the knife AND the gun. (00:15:25)

Man of Science, Man of Faith - S2-E1
Visible crew/equipment: Just as Sawyer's raft falls apart, we get a shot of Michael on his raft. In this shot, a wire holding his raft in place is visible at an angle in the water. (00:21:00)

Man of Science, Man of Faith - S2-E1
Continuity mistake: When Kate climbs onto the ladder of the hatch, she has both feet on the ladder from the top angle. But when the shot changes to below her, she still has 1 foot on the edge of the hatch. (00:24:50)

Man of Science, Man of Faith - S2-E1
Continuity mistake: When Kate drops the torch in the hatch, its position keeps changing between shots of it. (00:26:20)

Continuity mistake: Just before Michael says "You're going to pull the bullet out with your bare hands?", Sawyer's hair is very wet and pulled back, as if it were in a pony tail. When the camera switches back to Sawyer saying "You got a better idea?" his hair is a lot drier and covering his face. In the next shot, it is pulled back again. (00:15:10)

Continuity mistake: When Mike and Sawyer climb onto the pontoon (after Mike shoots the shark) there is a long wooden beam protruding to the left of the pontoon. In the next shot (morning, where Mike is crying) the beam protrudes the other way. (00:35:00)

Other mistake: In the scene with Sawyer and Michael drifting on the pontoon, where Michael is crying, you briefly see a boat with a mast in the background in one shot over Sawyer's right shoulder as he faces the screen, just before he says "Are you all right Mike?". (00:38:10)

Continuity mistake: When Michael is finished talking with his ex and Walt at a park, over his right shoulder can be seen a dark-haired woman in a black halter top and green slacks walking away. The camera shifts to the opposite view where Michael is looking, and the same woman is seen leaving a newsstand in front of the ex. (00:39:00)
Orientation - S2-E3
Continuity mistake: While Jack holds the gun on Desmond, who is running away, the stains on Desmond's garb change, particularly the very large reddish stain on the right side of his chest that disappears in the wide shots.
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.
