Excellent article. This is a film that all but removes the barrier between the audience and the film. Watching it simply brings back the escalating horror of seeing the tragedy unfold on TV, in many respects. But it is a superb, almost unbearably intense piece of work.

It's also a rare example of the "plural protagonist" film - ie the protagonist is all the passengers on the plane, none of whom are developed in terms of individual characters. They are a collective force, much like the plural protagonist of the underclass in Potemkin, or more recently the plural protagonist of the British Army, in Dunkirk. What is important isn't their backgrounds, but the way they make the right snap decision when they realise there are more of them than there our terrorists. This film honours their heroic memory.

It's also great seeing Ben Sliney and various others playing themselves, in the air traffic control scenes, recreating that appalling day.
