I say that all the time.

As we both know, small angular errors build over distance to bigger and bigger distance error. I'm never satisfied with the resolution of the downhole survey data I work with (0.1 degree) but that's what I get. I never trust reported compass readings below a degree. It's possible to get seconds with a brunton, but I don't believe the average field geologist is going to take the time to do that.

But the overall point is that if two guys see a UFO, they should separate by a short distance and point at the thing. That alone would give them a visual reference of height.

This could be done using many eye-witness estimations of direction - but they would all have to be at the same time! I never see a map with all of the observation directions plotted on them. Maybe Lindy can provide a link to any studies that used a multiple triangulation approach.
