K52 - You appear to think that the AAIB ruled out technical issues, however this is emphatically not the case. Please read again the following quotation from the AAIB:
"Where there is no fault found that does not mean that there was not a fault present. In this case I found it probable that on the engineering side as far as I could see there was not a fault highly relevant to the accident, but I certainly could not dismiss that possibility"
As to your second point, regarding a conspiracy, I am at a loss - what conspiracy?
