I just find it sad the crap that is posted here after every accident. Let the authorities deal with it and stop the one-upmanship.
A couple of factors at play here, human nature being the strongest factor. Whether you like it or not, people speculate. If you don't like it, don't click on the thread, you know what will be in here.
People.....pilots want to work out what happened, for a number of reasons. So they can learn from it, so they can design training scenarios. If it happened once, it can happen again.
Another factor, let the authorities deal with it? We're talking about the ATSB here, the organisation of 3 year investigations. What do you expect pilots will do? Sit around and wait 3 years?
You've been a member of this bulletin board for quite some time. You should be able to work out which comments are worth reading and vice versa.
