The first thing we learn at IFALPA about Accident Investigation is to abstain from speculation. The investigators in this case have all the evidence and the recorders in good shape at their disposal. We will get a preliminary report quite soon. As profesionals we should keep our twitchy fingers off the keyboards.
Let us respect our colleagues who did a wonderful job. The MOST IMPORTANT fact is there was NO LOSS OF LIFE.
Might appear pedantic, I grant you but to me, the second quote (from the same post) contradicts the first.
Anyway, apart from a redirecting link to the forthcoming AAIB report, what is the purpose of any post on this thread/site if there is not an element of speculation involved?
