08 May 2008 London, England to Denver CO.

Flying
I have always loved flying.
You get a real sense of the size and scale of our dilemmas and our dreams.
You get this (or at least I do), from being able to clearly see the curvature of this planet, this rock, our Earth.
Plus, its always sunny up in the jet-stream.
Saw an ice-shelf. I wonder how many more times this will be possible from this flightpath?

Low cloud.
We're flying (intermittently) at about 10,000 feet and I see tracks, indentations and almost physical shapes in this vapouric meringue of condensed air. Greenland's western mountains pierce this gossamer blanket.
Then, almost imperceptibly, these low clouds give way to snow, snow which becomes ice made from the sea.

Later:
Head wind: 5 mph; Outside temperature: -68c: Ground speed 556mph, crystals form on my window like mitochondria on a single cell, framed by the aircraft porthole.

Pre-Denver
Surprising in the rectilinear patchwork which makes up most of the geography visible to the eye from this height (more of which, next) - Crop circles!
Not those humorous geometric patterns made by beardies and cider drinkers in the summer months in parochial Olde Englande, but circles of crops! In each impeccably exact square of tenure, there grew a circle of some cereal crop or other.
Why?
Is it because of some subsidy to not turn the whole of the mid-west into a repeat dustbowl disaster, or is it for some other and so far (to me) confounding peccadillo?
Answers on a postcard please!
Denver, the mile-high city. We cheat, the plane doesn't really need to land so much as slow down in mid-air.

And yes, you do really feel like you're nearer to the sky!
