Should thread be closed?
I should stress at beginning that I'm not a pilot, professional or otherwise (unless you count PPL 50 yrs ago in a Tiger Moth , open cockpit, no electrical system, no brakes and only air to ground comms a Verey Pistol!!)
However, I do see a reason to keep thread active. What I think I am seeing from authorities is that as finding the aircraft becomes less and less likely, they become more and more definite in attaching blame to the aircrew. This thread does keep things balanced and evidence based. As fellow pilots I think you have a role to protect your colleagues from a rush to judgement unless and until the evidence clearly supports such a judgement.
