Heights Good I can appreciate your protectiveness and probably many others would share your concern for any "upset and hurt to those involved" but I cannot understand it. I have read the (redacted) Boards of Inquiry concerning the accident (its freely available on the web) and whether you agree or not the findings have been established. They are (briefly) summed up in Hansard as follows The board concluded that the main cause of the accident was controlled flight into terrain, brought about by the handling pilot’s disorientation due to the use of an incorrect technique for a dust take off. A number of contributory and aggravating factors were also identified.
Where exactly is the speculation?
