The whole reason a pilot made that video is because there’s a huge problem in the airline industry right now.
Many of her videos were about her dream of being a pilot, and a few trolls on the internet reporting her grounded them
But a pilot with suicidal ideations, or taking hallucinogens, like Emerson from Alaska Airlines Flight 2509 (the flight discussed in the linked video), would not be allowed to fly. And that's exactly the way it should be...
The issue is that many pilots don't seek treatment for mental issues because they imagine that they'll be grounded if they do, even though FAA policy, and most airlines' policy, is to allow them to continue flying.
You’re forcing people to pretend like they don’t have suicidal thoughts. That doesn’t work. Attitudes that it somehow does work are backwards.
