I will try to do that soon. Just upgraded computers and don't have a USB-C to Lightning cable yet to download.
But basically, I hovered the Air, then put my hand under it (about an inch underneath, toward the front so as not to block the vision sensors) then did the CSC and it shut down and I caught it (as I think I mentioned, it took a few seconds and seemed to slow down before it shut down completely). I'm not aware of any reason it would think it was in an emergency situation except that I only had about 7 GPS satellites, as I was just concerned with seeing if it would work and didn't wait to lock onto more.
