Is this an animation?
The shadows of the rocket and the water tower are not parallel.
No, it was a windy day, the rocket was leaning into the wind.
You’re seeing barrel distortion caused by using a wide-angle telephoto lens.
Good eye, I believe you are correct, it does not line up.
No, it's not.
Unless the camera itself was mounted to a small quadra-copter-like remote controlled device (and therefore at altitude, the size of which would cast no shadow), where's the shadow of the airborne camera? It literally lines up perfectly with the rocket and Sun during the decent. So perfectly, in fact, one might almost expect the shadow to have been cast on the fuselage itself.
The video quality and panning control seem to suggest it might have been a full-size helicopter.
