I'm fairly late to this discussion as I never saw the movie at the cinema, but just watched it at home. I do like aviation movies but I don't like it when things are exaggerated when they don't need to be. Surely this story was dramatic enough without needing to go overboard. Case in point, this shot from the movie as they are approaching the George Washington bridge:
They are clearly well below the top of the GWB towers (500ft) as those tops are above the horizon, and yet they are discussing with ATC whether they can make Teterboro. This makes the pilots look stupid, but actually in real life at that point they were at 1300ft.
Compounding this in the movie from this point it takes them another 2m47s to hit the water!! A descent rate of 180ft/min and an impossible glide ratio of 86:1, more than even a performance sailplane - no wonder the whole sequence feels false.
Again, in the actual incident they were only 1m55s from ditching, a descent rate of the order of 650ft/min, and a real glide ratio of approx 20:1.. why stretch time out? In reality what Sully did was remarkable in the short time available, when a dual engine failure was such an unlikely occurrence, how well he did to accept the situation and fly the aircraft.
Finally, the whole courtroom setup of the NTSB ‘prosecution’ was totally wrong, especially with the sim team on the video link testing out various landings ‘live’.
So overall, disappointing, I was hoping for much, much better.
