Character mistake: At the memorial service the principal says that it's been 39 days since 39 loved ones had died. But there were 40 students on the plane and 4 chaperones, making the total 44. Now 7 people got off the plane, which means 37 people related to that memorial service actually died, not 39. Two pilots would make up the numbers, but there would be flight crew too, which still leaves the numbers off.
Character mistake: In scenes following the plane crash, authorities refer to the 'National Transportation AND Safety Board.' The organisation is called the 'National Transportation Safety Board' - no "and".
Character mistake: The scene where Clear is trapped in the car and Alex is trying to save her, he incorrectly tells her the tires are grounding the car and to not touch anything. Rubber tires insulate the car preventing the charge from reaching the ground. If Clear were to get out of the car touching metal on the car and the ground at the same time she could be the conduit for the charge to pass through. (01:25:50)
Answer: As Alex picks up the fish hook he smiles and says "tetanus". Although not ideal, Death hoped to infect Alex with tetanus, a lot slower a death than intended, but a death nevertheless.
