The Artic Cicrle

On the flight over I was watching the flight tracker on the screen in the plane, when I saw that we were at our northern most point near southern ice land ( in the middle of the night ) I opened the blinds on the window of the jet to look north towards the Arctic circle, the big dipper was the entire sky, it went from the horizon on the west all the way to the horizon on the east, it was amazing and so crystal clear. It was so bright you could not see any other stars, a sight I bet only pilots get to enjoy.
