Denzel Washington is a seasoned pilot. He is alcoholic. In his latest flight that has gone awry, he miraculously crash lands the plane in an unconventional way, saving 96 of the 102 people on board including himself. He's hailed as a hero, but investigation still needs to be done. There are more questions than then there are answers as to what really happened during the incident. This is what the film is all about.
The two best things about the film are the execution of the incident and Denzel Washington's sustained acting. There's nothing much noteworthy about the story after the crash landing, having it reduced to a mystery, just like any other film. I don't mean it's bad. Actually, I like the film as a whole.
