Mr Husted, If
You think I am unaware of Blade profile and icing, I may be completely unable to understand your writing and discern some data from it. If so, the fault is mine. I admit I cannot easily understand your prose and what it is intended to convey. I may be too demanding in my definitions and usage of vocabulary incorporated in your posts. I can only say I took your reference to "Destroyed Aerodynamics" to mean other than airflow related to turbine compression. My mistake. Your issue was addressed long ago, and at length. I do not think it applies to this incident. Do I have a better explanation? It isn't my job to assess speculation and theory. You may be correct, I think no one is in a position to say. That's a pretty extravagant challenge, sir.
