Factual error: During the hearing where Sully and Skilles are listening to the recording of their conversations, we are given a flashback of the actual event. As the US Airways jet is taking off LaGuardia, we are briefly given a shot of the NYC skyline, with One World Trade Center appearing fully complete. One World Trade Center did not appear fully complete like this until mid-2013, and in 2009 (during the events of the film) construction on it had barely reached street level. (01:18:50)
Factual error: The cockpit voice recording is highly sensitive in nature. It would never be played in front of hundreds of people like in the movie.
Factual error: The NTSB was portrayed horribly in this movie. They investigate purely on facts, not going on witch hunts like this movie implies. In the movie they tried to "second guess" and "blame the pilot." This never happens in real life.
Factual error: When the A320 taxies out from LaGuardia there is a Continental airlines jet with scimitar winglets. These were not on commercial aircraft in 2009.
Factual error: During the flashback to the F-4 flight emergency, the visuals are inconsistent with the dialogue: they are approaching runway 21, which has a runway heading of 205 to 214, and the visuals before the dialogue shows them lined up with the runway. The dialogue of Sully's back seater is "Heading 020, five miles out, sir." This is 170° away from the runway heading, almost the opposite direction. (00:41:31)featherwinglove
