Chuck,
Of course you're right. BUT we are all trained to do that, we do it, and still accidents happen, caused by the factors we're talking about, sometimes with very experienced people. Maybe there was never any place for them in aviation. But if that's so, how do you identify the people who shouldn't be flying, who might have that accident years and years down the line? And most people learn from ONE mistake, but sometimes that one is catastrophic and therefore too many. People are human, not machines; they sometimes make mistakes. You know that...I know you do.
WHY are so many people here saying things can't change? WHY are you so defeatist? We have one language for radio communications; OK, the French ignore it sometimes, but most of the time it works. Aviation HAS changed over the years, in many ways. So why not in some relatively minor ways that might make for safety?
