The protection offered by the normal law flight envelope would not have allowed the aircraft to enter the same unsafe flight condition as the Boeing. I would like to see how they recovered from the aircraft "falling backwards". Great reporting as usual by the untrained.

I'm just wondering which switch, next to the door unlock switch, is labelled "Perform aileron roll", its not on my NGX, did PMDG miss something?

This sounds like a pile of cr@p to me too..
Even with the autopilot commanding the aircraft (as it would be on cruise) there is a bank limit restriction normally (right there on the MCP, combined into the heading select knob). However if a pilot fell asleep on the control column and put all his weight on, let's say, left bank, then unlike the airbus there is no restriction stopping it from rolling 130 deg and throwing the pilot off the yoke laugh.gif (and suddenly awake)
I look forward to the investigation results. As Glenn said above, this sounds like the media getting it wrong (again)

According to gizmodo - rudder trim knob?

Hmmm good point! Excessive yaw could result in a very fast roll over.

I looked at it from the FOs seat in my PMDG NGX. The door unlock is a rotary knob at the back edge of the centre console. A few inches away from it is the rudder trim, also a rotary knob at the back edge of the centre console. I'd say that inadvertently holding the rudder trim knob hard over to the left for any length of time would do the job quite nicely.

Airbuses don't have these confusing rotary knobs.
They have voice recognition.

After his toilet break the captain approaches the cockpit and says:
"Door, this is your Captain speaking.
Let me in.
"
It opens, and then locks it behind him.
The toilet also flushes by itself.

The new Boeing Dreamliner also doesn't have any confusing rotary knobs.
They are all lozenge-shaped, and some are flavoured.
