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)NoDouty
Factual error: When Denzel checks his iphone, the lock screen shows a date of October 20 and the time is 1:17. After unlocking the screen, the calendar icon on the phone shows the 8th as the date, and the time as 8:52. The battery remaining also changes.
Factual error: During both the takeoff and (crash) landing sequences, the altimeter is shown close to an altitude of zero. An aircraft altimeter is always set so that "0" represents sea level, not the local ground level.
Factual error: When Whip finishes his walk-around, he meets his First Officer and asks: "have we met before?" or something like that. In the real life, you meet your crew in the crew room, give them a thorough briefing, so when you go to an airplane, you already know the people you're going to work with. That's the place you introduce yourself, not the flight deck. It's impossible to meet your FO on the flight deck, without having met him first in the briefing room.
