I said operating from a submarine because of the reported disturbance in the water. The witnesses said it wasn't one, but if they were seeing other strange things, and not expecting a submarine to be there, then IMO they could easily have been mistaken. Alternatively, it's all lies. Both those scenarios are IMO more likely that natural phenomena, because there is no other known natural phenomena that moves in any way similar to the reported UFO.
