I'd never want to do any of those jobs, all three of them have positively awful working conditions, with the last usually resulting in lifelong mental damage from repeated jarring of the head (in addition to injuries), and most school districts & airlines push their teachers and pilots to the edge of the law, whether it be student load (and putting special needs students in classes with overloaded teachers illegally), or leaning on pilots to fly with the absolute minimum fuel they can get by with, despite regulations.
