Would Chuck Yeager count as an old bold pilot?
Bold = Fearless and daring; courageous.
I think Chuck Yeager knows fear - but also knows his abilities and falls back on his experiences and training. He is courageous - but not in a bad sense.
Personally, I believe that - training and courage trump fear.
The "bold pilot" in the often heard saying (old/bold pilots) are the untrained, risk takers, thrill seekers - they aren't the highly trained agressive pilots who take well calculated risks to push the envelope.
