I like how this reminds me that even though the clouds are pretty, the harsh reality is 30,000 feet is an extreme environment. Our technology allows us to visit places where we cannot survive.
I can't tell if the patterns on the window glass are scratches or frost....or both. It does give a wonderful effect though, one of motion to my eye, especially at the bottom of the window. Great idea incorporating the stuff that obscures the view INTO the view! And that tiny frost pattern (I would imagine) looks like a tiny Christmas tree in the middle of the clouds.
