Guys and Gals, I'm not going to get into any more tit for tat posts to spare everyone the labour of reading them.
As an accident investigator myself, we need to start by sticking to what we know as fact, not what I heard on TV, read in the Daily Terror or some spokesman came out with. The two rules of what not to do are, use emotion and get emotional.
The way I look at accidents regardless of if there are no fatalities or 6 in a single event (which is the most I've been involved in) is to ask 'why' four or five times.
Purely hypothetical, example of the 5 whys.
Why did the aircraft crash in the Indian Ocean - because it ran out of fuel and was off course.
Why was it off course - because the pilot was incapacitated
Why was the pilot incapacitated - because he was hit over the head
Why was he hit over the head - someone smashed their way into the coughpit
Why did someone get into the coughpit - because they wanted to destroy the aircraft and people. Reason unknown.
There are other methods but this is the simplest anyone can use.
