Yep I suspect all those responses are correct, although one does wonder how the group that build the brick wall, and flame anyone asking about the elephant in the room, can then engage in meaningful debate later on.
If we truly want greater safety and posting in here isn't either just gawking at someones misfortune or another forum to become mawkish then proper debate should be encouraged because then the pitfalls are discussed now, not two years later when an AAIB report gets published.
