Airplanes in flight, snapshotted?

Got it in one!

That would explain the arc over Iceland, but it seems too dense overall, and wouldn't explain the yellow dots in random parts of the ocean. Also, whatever it is mostly skips Australia and skips Japan even more, while being very US/Eurocentric, but not confined to land...

CAPTCHA, really?

It's the middle of the night in Japan/Australia in this snapshot, hence the relative lack of traffic there.

Huh. Then surprisingly heavy China traffic, and light S. American.
