I watched it two times already. It is amazing!
As always, some things are not correct. As a pilot, I see some inconsistencies, like a glass cockpit in such an old plane, with two engines over the sea in clearly not an etops plane, they mention MH370 disappearance, but still flying in this old thing? Don't think so. A plane can have lightning, no windmill outside whilst no power, gaining 3000 feet is useless to get over a cumulonimbus and the pilot flying doing the radio at the same time.
But hell, what a movie. The fighting scenes credible, the actors very good playing, emotions realistic. I loved the movie, the editing worked beautyful. We don't get these movies not anymore these days.
