I just researched that. They are one of our customers too. WTF....that was a bizarre incident. They were running out of fuel and were no big deal about it. I heard the ATC recording.
It won't. They already went there with testing equipment and could not find a significant error. But clearly the evidence points to something being off.
Yeah that video certainly is not 7”/hr. We had times where we approached 5 or maybe even more last March briefly in some of the most intense snow rates I’ve ever seen and it was near zero vis.
