Like most professionals I actually await the official report because it affects me and my colleagues.
Re the flightdeck door, I was only passing on what is in Flight International this week, a better source of info I feel than Pprune.
Whether a flightdeck door will 'unlock' electrically in an impact is a matter for future speculation. Just because the electrical supply has been lost does not mean the door will be open.
I am of course biased because I have always been of the opinion that the doors serve only to persuade the public that politicians are doing their bit to stop terrorists. Rather than do their jobs properly.
