Rubik101,
if a uniformly harsh and critical approach to criminal negligence was adopted universally, flying would ultimately be a safer industry.
You seem to be assuming that every accident is caused by criminal negligence. They are not. How many
are actually caused by criminal negligence where every other pilot needs to be taught a lesson? Very very few. But throw a pilot in jail and the aviation world will become a more dangerous place.
All your policy will do is clam the whole system up, with everybody refusing to utter a word, and flight safety will go down, not up as you predict. Your black and white big stick approach will not achieve what you think.
