As a CFI, I have a moral and legal obligation to teach good habits and set good examples.
I totally agree. You have to teach a student to fly in the safest way possible and they should continue to fly that way for a while until they become more experienced.
An important distinction here is that Henry is not a new pilot nor is he YOUR student.
Also, just like a friend of mine who taught in R22/R44's, he came to work for us and soon realized that everything he taught the student NOT to do is exactly what you need to do when your using a helicopter the way it was designed for. Yes there is more risk but if you could accomplish the mission flying how you are taught in flight school you could do the job with a much cheaper airplane.
As to Yosemite, Half Dome, and El Cap in particular, I'm also a climber, and having my experience there (or at other sites) disrupted by a rude pilot really ticks me off.
And here we have a totally separate issue that is very common today. Hikers don't like Horses on "THEIR" trails. Horse riders don't like bikers on "THEIR" trails. Traditional mountain bikers don't like electric bikes on "THEIR" trails and... apparently climbers don't like aircraft anywhere near "THEIR" climbing areas.
The important point that many are forgetting about PUBLIC LAND is that it's for EVERYONE to use and enjoy in their OWN WAY.
As long as they are not going out of their way to continually fly by you or are flying too close to you that they pose a safety hazard, my suggestion is just wave (Kidding, I know your hanging on for your life
) and continue on enjoying your climb.
I'll share my pet peeve which is having to listen to someone's music while I'm enjoying nature. I am not a music guy and typically don't like the music they are playing BUT it is public land for everyone to enjoy in their own way.
