Is it a cloud or a flying saucer? Both, but it sure isn't an alien ship. Lenticular clouds can be shaped like a saucer, and they can fly by virtue of the fact that, like most clouds, they are composed of small drops of water floating in the air.
Lenticular clouds usually form from high winds that blow over steep terrain, and stand out when there are few clouds in the sky. A lenticular cloud can take very strange forms based on layers. A couple who stopped the car near Yellowstone National Park in Wyoming, USA, took the picture of this lenticular cloud behind those picturesque windmills.
