This was almost the first thing that was taught (not demo'd) to me when I left the military, and this was a small company in Scotland - as the man said, they are out there! Having come directly from the Scout, it wasn't that scary, but it was a 206, and I was told not to trust anything other than a Bell product if I had to rely on it (like any good Chief Pilot, he also told me not to get into a situation where I had to).
The robbie wasn't around when that happened, but if, as I hear, you have .9 seconds to get the pole down, you gotta be nuts to try it.
