I have looked at my logbooks, and I can say that I have experienced roughly three hundred Stalls, always on purpose, and never alone.
Maybe half that number of Spins, again, always on purpose, and never solo.
I have no idea, what the 330 is like. If I have suggested I have even a clue, I am deeply sorry. I will say that I have experienced controlled descents with a Stalled wing (s), but that is not pertinent either. I know.
Bottom line. Virtually none of the conclusions expressed here give me comfort. I think the pilots are given short shrift, and through time, innuendo, slur, and lazy data have cemented their legacy. And that is so wrong.
