Factual error: When flight 227 departs Orlando, the thrust increases for 3 minutes. It should have increased for 30 seconds.
Continuity mistake: When the movie starts, in the wide shot there is no cellphone on the night table on the left at Whip's side. In the close-up a cell phone appears.
Continuity mistake: When Whip goes to see his ex-wife and son, he parks with a fire hydrant by the front right fender. He takes a drink, gets out of the car, and the fire hydrant has vanished.
Continuity mistake: When Whip is watching the crash on TV, the (CGI) plane seems big while flying against the church, but when it lands and it's seen in comparison with the people on the field, it is awkwardly small.
Continuity mistake: When Nicole knocks the box with the syringe and all the drug-stuff, the syringe falls far away from the box, but it appears very close to it in the next shot.
Chosen answer: Popular mechanics wrote an article covering this. In short, inverting a passenger jet is certainly doable, but the specific chain of events seen in the film are more of a stretch. Possible, but...challenging, to say the least!
