So, to make sure I understand, the three of you feel it is appropriate for a safety pilot to read a book while the other pilot is under the hood? And if someone questions that, they are on a "high horse"?
You are certainly entitled to your opinions, as I am mine. I guess we'll just have to agree to disagree. Flying really is serious business, although the excellent safety record it enjoys often makes it appear otherwise.
By the way, CE650, what do you consider to be going "far" in aviation?
