This is kind of funny. There's no sound, but you can almost hear the person with the camera, who appears to be filming a docked barge, say, "What the...?" as the camera snaps up and just misses the plane going down. And even though you don't see the plane hit, the video tells you a lot: the line on the surface of the water shows that the pilot must have been able to skim the plane lightly along the water for a very long way, and as the camera zooms in - it's just a plane floating calmly on the surface. (Just? Wll, you get the drift.) It's all very non-traumatic, from this view. And you can even see people pop out of the emergency exits in just seconds.
Bonus: "Obamas Juggle Inaugural Balls." Ahem.
