Most of those are fake or not what they seem. Take the one at night--notice the color of the three lights. Coincidence they're the same color as the light emitted from a sodium-vapor lamp? I don't think so. The last one was editing tricks. The third looked like a cgi-scene out of a sci-fi movie. I don't know what to think of second to last, and the first, I assume, was a hovering object that dropped into the sea. I don't know what to make of that one.
