The camera man did not SEE any "craft", he is filming the storm front only.
If they had been there for real in the shot he would have snapped onto them immediatley and zoomed in and out and followed them in CENTRE of shot.
Camera is moving so camera man is looking and adjusting the shot. This means HE DID NOT SEE ANYTHING UNUSUAL apart from the storm front he was filming.
This means they are post production additions and are fake.
