As I’m sitting here at the kitchen table getting ready for supper, I look out over the patio and notice a jet contrail in the sky. Normally I wouldn’t pay much attention, except the contrail is dark. And the jet is apparently doing a U-turn.

Undoubtedly the trail is dark because it’s nearly sunset and the sun is creating some odd shadows in the sky.

To the right of this little spectacle we have two smaller contrails, presumably further away, that are running in parallel with each other, same direction, same speed. That strikes me as odd too.

Now I’m going to have to pay attention to the sky and see what’s going on.
