Continuity: When Tom removes the toy airplane from the lunchbox, the three propeller pieces are completely broken off of the left wing engine (all are intact on its right wing). Yet, earlier on the island, when Kate twirls the airplane in the air, before Charlie joins her, the left wing engine has grown one piece of propeller that is unbroken. There are other moments such as this, in other episodes.

Continuity: After Kate's confession to the other survivors, she kneels down and scoops up the toy airplane with some sand. However, the next shot is a close-up of the airplane with its nose in the sand, in front of her.

Continuity: When Kate burns Joanna's passport photo in the close-up the corner of the book burns up, yet in the wider shot the corner does not burn, and in the next shot another change, including the lighter. Later, when Sawyer holds up the passport, the burned page edge is just a bit singed.

Continuity: When Sawyer dumps Kate's belongings out of the backpack onto the sand, their positions on the sand change between various shots.

Visible crew/equipment: As the raft sets sail with Walt, when Vincent runs into the water chasing it, Walt shouts, "Stay Vincent!" At the start of the next shot, on the right, the crew's vessel/equipment is quite visible.

Continuity: When Sun and Jin sit at the table at the airport, both cups' lids are on properly, yet for the "spill shot" one lid is askew, and Sun's hand changes between shots to be in perfect position to knock the cup over. Things on the table instantly change positions, such as the clear plastic croissant container that jumps back onto the red tray. This applies to Exodus 2, as well.

Visible crew/equipment: When the raft leaves the island, you can see the shackle and wire used to tow it.

Continuity: When Walt notices the pillar of black smoke, in the overhead shot everyone gathers well behind the raft, including Claire, who was just sitting in front of the bushes in the previous shot. However, in the next shot, all the survivors are now gathered at the side of the raft.

Continuity: In the hotel room, while Walt watches TV and when Michael runs after him, the pillows, things on the table, etc., move around between shots.

Continuity: While Jin is finishing up work on the raft, Sun walks over and when she holds out her translation notebook, the way she grips it is very different between shots.

Continuity: When Danielle approaches the beach campsite, in his close-ups, Walt hides beside a tree and holds it with his left hand. However, in the shot between his close-ups, facing Danielle, Walt is hunched over with his hands leaning on his knees.

Continuity: On the way to the Black Rock, when Danielle removes her sweater Locke notices the long scratches on her arm. Later, when Claire questions Danielle about the actual scratches are very different and their positions differ.

Continuity: When Jack and Ana-Lucia sit in the airport lounge she takes out her cell phone when it rings, and in this shot her glass is nearly full and has plenty of ice. Yet, when she leaves a moment later, the glass is nearly empty with no ice whatsoever.

Audio problem: After the airport scene where Sun spills coffee on Jin, it cuts to Sun approaching Jin while he is fixing and banging on the raft. The banging sound isn't synced with him hitting the raft.

Continuity: When the group stops to rest on their way to the Black Rock, as Locke speaks to Danielle, he holds the right or left backpack straps with either his right or left hand, depending on camera angle.

Visible crew/equipment: After Kate throws dynamite down the hole, when Jack pulls Locke up, the green straps (for device used in the stunt) going round Locke's pant leg are clearly visible.

Continuity: When Sayid goes over to Shannon to help her with her luggage her trunk falls down open and some clothes fall out. Then Sayid picks up some shirts. But when it cuts to Shannon grabbing them from him he is holding fewer and different looking shirts than he picked up first.

Continuity: After Sawyer ties the rope to the rudder, they pull him toward the raft. In the shot just before Michael says, "Come on, buddy," the sail is completely up, yet in the previous and following shots the sail is down.

Deliberate "mistake": On their way back to the hatch with the dynamite, Kate, Jack and Hurley run from the "monster" but Locke runs toward it. When he lands on his back the shot cuts away to the "Lost" logo floating onscreen. When it cuts back to Locke, in this shot the bruise is over his right eye, instead of his left. The shot is flipped.

Continuity: 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.
