Mentour Pilot is for people interested in aviation. He does breakdowns/analyses of plane incidents—not just crashes. He's also a certified trainer on at least one type.
It's funny, I was also thinking about Mentour Pilot, both because of the whole discussion here, and because of the post upthread talking about clickbait. I love Mentour Pilot once I get into one of the videos, but looking at all the attention-grabbing (and clickbaity!) stills on his video list makes me have to force myself to remember that it's fine once the video starts.
Mentour's recent videos have become much more fake salesy ultra-high energy. I actually had to unsubscribe.
The same phenomenon is unfolding in chess youtube world. The audience of laypeople (with minimal to zero chess knowledge) who are entertained by yelling and extreme over-excitement and butt-plug cheating scandals is 1000x as large as the audience of true chess nerds.
