Black Triangles

What you're seeing here, according to the UK Ministry of Defense, can be explained thusly: "black triangle" class UFO sightings are caused by buoyant formations of high-energy plasma electricity created between multiple meteors simultaneously entering the atmosphere. These meteors are theorized to occasionally emanate between them an energy field that refracts light, producing the appearance of a black polygonal shape with the lights at the corners made up of the burning meteors themselves.

I feel much better now knowing that huge hovering mechanical three dimensional intelligently controlled geometric object with the pulsing lights was simply an atmospheric anomaly.
