James Leng, as he is known in the real world, said on his Flickr account:
On my night time flight back to SF from Amsterdam, I noticed that the lights from cities were making the clouds glow. Really spectacular and ethereal - it was really seeing the impact of urban environments from a different perspective. Each glow or squiggle represents one town or city!
Luckily the flight was half empty, so I was able to set up an improvised stabilizer mound made up of my bags, pillows, and blankets for my camera to sit on.
We were around the midwest at the beginning of the clip, and there were fewer cities once we hit the rockies. the bridge at the end is the san mateo bridge.
What ensued was a beautiful display of how much man really does control the world, set to a lovely tune. Check out the video below, but if it doesn't work for you, check out Leng's Flickr account for the video. We don't think you will be disappointed.
