I have flown with two guys who fit this category. They use reckless flying as a means to prove that after all, they are really somebody. In every case they were either emotionally abused when they were young or physically demeaned by genetics. Inferiority complex, insatiable machoistic egos, and / or adrenalin junkies play into it too. They all eventually came to an ignominious end where they either broke too many rules and had so many " incidents" that they quit or had to quit flying. Judgment goes out the window and, "Watch this, I do it all the time" takes control. I learned early not to fly with just anybody and to take time to see who is pendantic about what they do to insure a safe flight.
