Visible crew/equipment: As Locke and Eko descend down the hatch a safety cable can be seen supporting Locke.
Continuity mistake: When Locke and Mr. Eko watch the Orientation video in the pearl station Dr Chang has both arms and the screens behind him show people working in the swan hatch. His arm was badly damaged in the incident before the swan hatch was built and he should.have had a prosthetic arm when the pearl video was made.
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.
