Yes, no wind in that last vid. from 6 years ago. But did you see the second film in the original post?
It's called "Cross-wind at La Salette". But then Peuzin, himself, commented to camera after that circuit
that he didn't think it "prudent" to have another go.
In another of his La Salette films he admits to being a bit obsessed by its challenges.
However, for those of a mind to label his videos "irresponsible" he mounts his own defence in the Description:
[Per Google Translate]
"I do not wish in any way to contradict the academic message of training from official organizations nor to “push to crime” by the supposed bad example given to young pilots. I think everyone is big enough to know their limits. Finally, although I am a captain in commercial aviation, that does not make me a reference for mountain flying. I just want to shed new and perhaps questionable personal light, based on my experience of mid-mountain flight on wheels (snow on skis is another matter), my in-depth knowledge of flight mechanics and finally the management of the risk that I practice daily as an airline pilot. This first video presents the best example of my "neurosis" by its spectacular aspect, but it also shows the methodical nature of the approach. My next videos will be less spectacular, they will stay in in an educational register to expose my theory on the main and subsidiary risks by land and how to manage them."
(This has no subtitles but we get the picture.)
