Windy Wyoming as it's called. I live in the east side of the state - few hours away from where they did this.

While Pinedale is generally less windy, don't kid yourself, it changes constantly. Add in they did this test at like 8,000 ft elevation. The temperature is constantly changing.

I find it impressive they found a 4.4 mile stretch that was unobstructed, no risk to hitting something (person/critter) in that area. They found a ridge that allowed them a way to somewhat see the target.

No real world application for what they did, but the effort, the science, the planning - impressive.

I'm guessing they must have used GPS to find their location, and calculate the rotation of the earth. But even small changes - like repointing 1mm to the north or south would be huge over that distance.
