Eleven thousand meters

I woke up aboard the UA181 flight from Frankfurt to Denver. I've been asleep for four hours.

I look out the window and find a beautiful landscape of snow and mountains below us. Like one of those snowy top views from Game of Thrones.

Where are we? I think.

We're flying across Greenland at nine hundred kilometers per hour, eleven thousand meters above sea level, and minus fifty degrees Celsius.

All I get is a high-level view. No detail. No sense of scale.

I realize this is the first time I've seen Greenland.
