Unusual beam in front of plane

Last Friday I noticed something weird in the sky, a plane was flying high above with the usual contrails behind, but ahead of the plane all the way to the horizon was a black 'beam' which the plane was following. See example below, the one I saw was more defined though, what causes it?

Actually, shadow makes sense as the plane was flying East in the evening, never noticed it before though.
