2nd Hit Weirdness

Still really weird.

I don't know what would cause this in a real video of a plane. It doesn't seem to be motion blur.

One possibility is this background fuzziness is from an explosion occurring at the wall, that the CGI plane was being super-imposed over. They were trying to time the CGI with the explosion, but maybe this explosion didn't quite sync with the plane, so they had to cut out the blossoming explosion for a couple frames so it would match up better.

Hey-- here's a post from over 10 years ago, that still makes good points about the no-plane theory.
