Pilots can learn a lot from other pilot misakes. We can read about them so we don't do them again. I loved flying airplanes no matter what size. Retiring with no incidents was from seeing how not to make the same mistakes others have. I don't think I would change anything I did in my career. I started out with little airplanes and ended up in big ones. Loved all of them. I just wish the big airplane pilots today could still hand fly. I know some still can but the rest worry me.
