I found this pretty interesting and wonder if you have any thoughts on it.
I commented thus on the video:
" I’m not a pilot and my helo experience is mostly as a Huey crewchief in the sixties. The better pilots in my company were also fixed-wing experienced, and many were IFR qualified as well. The conventional wisdom among them was, (1) you can’t fly by touch and feel, you need to see. (2) Therefore, IFR in a helicopter mostly means “I follow roads.” and (3) in dense fog, even with instruments, it’s 9 to 1 you’ll be upside down within 90 seconds."
