I agree with Lt Hung. You cannot go round making statements that appear to be credible without finite proof.
I am also concerned that your profile does not reveal any aeronautical background, yet you write your posts giving the impression of a sound background in the rotary world.
I am unhappy with the implication of many of your posts without a clearer understanding of your background knowledge. Indeed, most of your surmise can be achieved by careful study of all the posts throughout the topic from the start, coupled with a few educated guesses.
The profile of the accident has been evaluated by many whom I know to be very experienced in the rotary world and on specific type. We do not need yet another round of theories based on nothing at all, or wild speculation.
I suggest you lend credibility to your theories by producing your background and evidence. Otherwise, stop wasting bandwidth.
