Factual error: Whenever the fire extinguisher is activated for a jet engine, that engine becomes inoperable. In the movie, the co-pilot first activates the extinguisher for the left engine, and 30 seconds later, for the right engine. At that point, both engines should be shut down. However, the engines are still operating (and revving up) and Whitaker even asks Margaret to apply full power, which is also audible. (00:23:00)

Factual error: When the plane's altitude decreases from 28,000 to 27,000 ft on the altimeter, the digits to the right of the 8/7 do not change.
