There is a strong military influence in aviation, and the military is designed to operate under horrendous conditions at times.They try to keep the masses "fat, dumb, and happy"and encourage the use of alcohol for this reason. As the dutch sea captain said, "for thoughts there is always gin"
Serious thinking is not encouraged. You have to think it will never happen to you. No realism.
Some of this attitude has rubbed off onto civil flying. There is ample evidence on Prune.
