That's really neat, thanks!

An interesting related fact is that with equal distance traveled through headwinds and tailwinds a slower plane will be relatively more affected. From ~12% longer time with a wind speed 1/3rd plane speed down to ~1% with a wind speed 1/10th plane speed.

That's one of the reasons it's easier to navigate in a fast airplane than a slow one (another being you see more ground in the same amount of time).
