Richardson said it could have been a ballistic missile launched from a submarine or an interceptor, the defensive anti-missile weapon used by Navy surface ships.
That isn’t enough for me but its enough for me to say that someone who see a rocket in that picture is not the equivalent of a flat Earther. And certainly not someone whose intelligence and sanity deserves to be insulted.
