Wonderful explanation. Coffin Corner is sensationalized. I think you describe how to avoid it perfectly. My point is that, by definition, once you meet its parameters, no escape is possible. If one reduces power, infinitessimaly as you will, you will infinitessimaly Stall. I don't disagree with anything you write, but it ignore's the definition of the concept, sensational or not. Neither argument is wrong. You are certainly a very qualified Captain, you have my complete respect. This is a forum, not a cockpit.
