UV,
Why do you insist on reading these threads and posting your stupid message, as this thread clearly touches a nerve. Why don't your just ignore it.
We can all learn from these sad events, and the sooner the better. We also should accept that 80% of accidents are caused by human factors.....accept it....don't get all upset when someone even suggests it (I know people who have come to grief in tragic circumstances as well).
Unfortunately it looks like another recent crash was human error as well......though the report in a years time may confirm this.
