UFO's Over Cataclysms?

While colorizing historic photos for Pearl Harbor's anniversary, MK Davis, film and photo expert and astrophotographer, came across something odd in the air.

Might this be a UFO witnessing the event? This has been reported at many cataclysmic and historic events.

How would aliens know about such events happening? Well, my best explanation would be time travel capabilities to come and witness events that were key for the people of the earth and their evolution as a species. In fact, it's entirely possible that the comings and goings of UFOs is simply their skipping through events and times, showing up even in the Middle Ages where they were incorporated into paintings and even in ancient man's cave drawings.

Could it be that things like thunderstorms and volcanoes erupting and the like produce enough energy for them to manifest somehow or perhaps enough distraction to come and go unnoticed versus still skies.

There are enough photos taken of such incidences repeatedly to the point that one has to wonder, is there another variable of intelligence in our universe that traverses a vehicle through catastrophes to witness, to incite, or to relieve the situation?
