Interesting? I have seen some funny lights in the sky doing things that one doesn't see everyday. I can say that the angle from the vehicle rules out a natural optical illusion. However one can use a small mirror on a digital camera and get the same illusion.
This is one of those things that a person would need to be present for the description to be considered, because there are a lot of ways to create such illusions. Anyone for instance can paste an object in the sky and make it appear to be hovering using photo editing.
Hey guy, thanks for your comment and insight! I think I found
the answer to it, but I'm always down for feedback if you're game.
