The Australian military shows its aircrew recruits a movie called "Broken Wings", a compilation of aircraft crashing.
Student pilots should be told that aviation isn't safe but can be made that way by knowledge and discipline then shown the movie. Aviation can be wonderful, exciting, beautiful and immensely satisfying and you can make mistakes but there are some mistakes that will turn around and kill you quickly.
Don't do anything stupid.
Unfortunately the regulator and ATSB aren't doing anything to make aviation safe, they just make it more expensive and difficult and reduce the number of people doing it and the hours they fly.
