Is It A Bird? A Plane? A Rainbow?

Is it a bird? A plane? No, it’s… a rainbow! This image is pretty confusing to look at. At first glance, you might think you’re looking at an airplane flying through to sky, but the longer you look, the more confusing you get. Is it a rainbow shaped like an airplane? This must be a trick of the light that’s caused an airplane to reflect light in a way that resembles a rainbow. It’s a pretty cool image that defies instant explanation but is explainable once you think about it.
