I wish people wouldn't armchair-quarterback people in situations that are (likely) completely outside of their experience.
I've gone through some helicopter safety training for SAR, and been picked up and dropped off by a UH-60. The pilots spend a lot of time briefing us on all of the things they are nervous about, and there are a lot of things that they're nervous about. All of our gear has to be tight and secure. Don't have our trekking poles on our backs (common). Some of it is about passenger safety -- where and how to approach depending on the situation -- and some of it is about the safety of the craft.
When doing a hoist by air, there are a lot of things that can go wrong and many of them will be fatal for the helicopter. We have a tag line that is used to stabilize a litter as it's being lifted, because rotor wash makes the litter spin dizzyingly (and here's what that looks like: https://www.youtube.com/watch?v=msw31_dw7hE https://www.youtube.com/watch?v=msw31_dw7hE), and occasionally the tag line or something else will get loose and end up in one of the rotors and then a lot of people have a really bad day (https://www.youtube.com/watch?v=NyuQ-XG7LbY https://www.youtube.com/watch?v=NyuQ-XG7LbY -- the pilot here is a total badass).
The areas around, under, and above the main rotor are completely unpredictable and if the drone ends up in that and gets bounced into the fragile tail rotor, it could kill the pilot and student. The pilot knows nothing about the skill or knowledge of the drone operator; putting the helicopter on the ground is safe and prudent in that situation.

One does not want to be surprised by things while doing that. Could an experienced pilot keep his cool in this situation? Of course. Is the pilot’s brain a huge factor here? Absofuckinglutely. But yes, if you’re just doing hovering exercises, there’s absolutely no reason not to just put it down if you see something unsafe nearby — you’re usually only ~10ft above the ground anyway.
- Pyxl101 9y agoThat first video looked terrifying. Is the cable also twisting and tangling while that’s happening, or is the litter spinning freely around it? Edit: I was expecting it to stop twisting and begin turning the other way, like string that I've played with, but it just ... never did. I can't imagine the tension that would put into the cable.
- thaumaturgy 9y agoYeah, I don't enjoy roller coasters, that would not have been my favorite SAR experience. Assuming they connected it in the usual way, it would have been twisting, but not so much tangling. It might tangle once everything was on the ground and the tension was off the line. I don't know what the hoist line material is; I'd guess a kernmantle of some kind but I'm probably wrong.
