Guys, do you remember Germanwings? I stated early on in the discussion that a plane doesn't go from cruise to crash very quickly. I was immediately mobbed on here when I suggested it was suicide. Now the bells are ringing again nearly 7 years to this day (24th Mar) and again I am being mobbed for saying this looks like a suicide event.
I have been on PPRuNe a lot longer than most that say don't speculate.
I do not fly the 737 but many on here do and this will be unfortunately another learning event for us all.
It is healthy for us to have a grown up discussion regarding accidents. This is how we learn in the industry. Our checklists, procedures and everything we do are unfortunately written in the blood of our deceased colleagues.
