HF = Blame ???
BOAC, indeed it is most likely that there was not a single hole called HF in the cheese.
But after reading nearly all the posts, most of them dealing with the logic of the airplane, some blaming the manufacturer, some defending, some highly technical, it just seems justified to point to one main factor: An essential and very basic manipulation, the retarding of one TL was not carried out by the crew.
This statement is not meant to overtake any investigation based on knowledge not available to this community and sorted out by true specialists. And most certainly it has nothing to do with blame.
I wonder why the simple reference to human factors immediately calls for an association with blame? Blame - at least in my opinion - is reserved for people acting careless or outright reckless. Human factors is not about blame, even if one accepts that a small part of Human Factors is about reckless behaviour. This is most certainly not the case in this accident.
But the HF issue is important, because it has feedback into other parts of the loop, like training, man-machine-interfaces, system logic and more. Therefore, HF probably yes, certainly no blame, and most important: learning for a lot of us. That's what I praise this thread for.
