Chronos - It is not at all premature.
Rather like your relationship with Mrs or Mr Chronos or your cat(delete as required) is based on physical AND Emotional factors.
Every pilot knows that there are numerous factors involved in the chain of events leading up to an accident.
The physical what happened on night, that is speculation right now.
The emotional, how pilots feel, morale, conditions of work, work ethic and why they were even there on a dark and dirty night are likely "more" responsible whatever the outcome of the NTSB/AAIB pure technical & flight factors. The we already know. That is what we're talking about.
It is not premature discussion at all it is highly pertinent. Now thanks to a brave soul in Doha on RT breaking international news and massively relevant. In fact so relevant that I would wonder why anyone would think it not!
