One of the reasons why some people here do not appreciate speculation is that a lot of the hypotheses could centre around pilot error.
If it is later found not to be pilot error though, the pilots could still be tarred with that as a reason for the accident. One only has to consider those poor bloody Chinook pilots and the effort that has gone into clearing their names.
That might be an extreme (and not entirely apposite) example but, as the rotary world is so small and many pilots on here know each other, it could be considered insensitive to discuss pilot error without having any hard evidence with which to back it up.
Secondly, when there are so many theories being bandied around, it is hard to distinguish fact from fiction.
I’m with Hummingfrog on this one. It is one matter to discuss something once the final report is out but another altogether when it's just a preliminary.
