The video maker has posted an update, which I post in full-
Hello everyone - quick update about yesterday's Rail Replacement Helicopter video.
The story was all over Swiss media on Monday, and I'm seeing a few comments saying that the helicopter has now become very busy with tourists as a result.
(My video itself may now be adding a few extra people, although the channel's Swiss viewership is about 1.5%, so hopefully not too many. And to be clear, I asked permission before filming, for this exact reason.)
Basically, if you are planning to go to Linthal in the next few days to try and get on the helicopter, please be realistic. As I said in the video, tourists are LOW PRIORITY. If you do not live or work in Braunwald, you may face a very long wait, and if it gets really busy, you may not be allowed on at all.
Also, please be aware that even if you manage to get a flight up, it doesn't guarantee you a flight back down.
Having said all that: it's is an absolutely gorgeous part of the world, with fantastic hiking trails, and it's 100% worth visiting even without the helicopter, if you ever get the chance. I'd encourage anyone to go there once the Braunwaldbahn is up and running again.
