Walter, have you any idea of what tuc is on about? Do you ever pause to ponder on what others have said, before you simply ignore or pour scorn on it? I have spoken up for you and said that you should be listened to, but it works two ways, you have to listen to what others say and answer questions they put to you. It has been pointed out that you purport to offer a cause to this accident, ie the misuse of PRC112, either by incompetence or malevolence, yet you offer no proof. To merely say that you imagined the scenario only to have it "proved" by the process of "QED" when you discovered that PRC112 could indeed have been fitted is total twaddle, to coin one of your phrases.
I am afraid that you are your own worse enemy, by adopting a belligerent and confrontational attitude to fellow PPRuNers who post here. To now state that they have "let down" the 29 people who perished in this tragedy is unacceptable and should be recanted.
As tuc has told you, if your theory was indeed fact, it could only have been perpetrated following the gross breaching of the Airworthiness Regulations, and if you had any sense you would see that and stop rubbishing those who have said all along that whatever happened to cause ZD576 to crash that fateful day, it was Grossly Unairworthy when it did so.
