Effectively what happens is the plane is being followed by the camera, then when it crashes the camera loses focus for 2s, then refocuses in on a dead body, pans around to a few dead bodies, and zooms out to show you a bunch of bodies and some wreckage. Like Gosling says in his post, there are no flames, no gore, not really even any smoke. What makes it so disturbing is that it's just lifeless bodies, instantly killed... just lifeless, no blood or explosions. I suppose that some of them may be unconscious, but just knowing that Gosling said most were dead or uninjured kind of makes me think otherwise.
