But in my experience, mistakes are the best instructors and equalisers i have personally encountered. Others' mistakes can feed an arrogance and are not quite as revealing as one's own.
And, no, i haven't crashed an airplane. Yet.
Your last sentence makes the difference. To recognize a mistake early enough to prevent the final fate of a mistake and walk away from the scene with new knowledge and dedication is a key factor of any given task. To put it plain and simple, you can learn from a botched approach by comencing a timely go around, there is no need to crash the aircraft and kill people by doing so.
Driving over an pedestrian with your car does not qualify to becoming a driving instructor, and killing a patient will not entitle a doctor to give lessons to medical students.
In view of this accident i can find no indications concerning an ongoing learning process of the crew to the root cause of the accident, not monitoring the basics of flying, airspeed, attitude and altitude. Instead we hear excuses over excuses.
