Dallas Here we Come!

Snapped this on the fligth to Dallas, the spots are ice on the outside of the window.
It was a 10 hour flight an this was taken some where over the US.
I can't remember from the moving map where we were!

This is the wing of a Beoing 777 if anyone is interested! Not a bad plane however this particular one was quite old and the entertainment system was a little suspect and kept cutting out.
