Corrected entry: The seats on the plane are filled with accessories (watches, dentures, etc) because the vortex sucked everything living. Then why wasn't their clothing left behind?
Corrected entry: When they all leave Bangor airport after they find it is deserted, they have to manually move a stairwell to the plane to all get on board, once they are all in, the plane taxis off. How did they manage to move the stairs away from the plane after getting in? They would have had to move the stairs away otherwise the wings would have collided with the stairs. Planes need a truck to back up.
Corrected entry: When the survivors of Flight 29 first wake up and start figuring out their situation, Jenkins tells Albert that everyone on the plane, including the people who disappeared, must have been asleep when the event happened - because if anyone was awake during the event (whatever it was) they would have screamed and awakened the others. But later, when they are about to go back through the time rip at the end of the movie, he shouts that everyone on the plane who was awake the first time they went through disappeared. We cannot dismiss this as Jenkins just contradicting himself or changing his mind - first, because there is no indication that he changed his mind or believed his initial analysis was mistaken, and second, because his initial analysis is just stupid. How could anyone think, even momentarily, that every single person on a plane, including the crew, could have fallen asleep at the same time? And if everyone on the plane had been asleep, why would only some of them have disappeared and some survived?
Corrected entry: When the crew of the plane enter the airport terminal after landing the first time, one of the passengers goes up to a lobster tank, and there are still lobsters in it. I thought all living things had disappeared.
