Similar to other clouds, contrails can cast shadows, in that an aircraft and its contrail are actually high up in the sky, while the shadow is cast downwards onto the cirrus haze layer by the sun or the moon. The thin layer acts as a canvas upon which the shadow is projected. In the end, contrail shadows are a captivating atmospheric optical phenomena that sometimes appears counter-intuitive. This example of such a contrail and its shadow was spotted over Columbus, Ohio, US.
