“”Until all the facts are in I bet it was a computer problem.””
Entirely possible the door lock mechanism was as affected by malfunction in computers as the plane itself could be. I’m not saying that was the case with the PLANE in this incident but a possibility with any A 320....
Not likely. If that was the issue you would have heard comments from the co pilot.
He would have had to be unconscious.
Also, there are pilot type of things that indicate this was a deliberate act.
Airbus had one plane where the pilot was pulling up and the computer said no we are going down and it did.
Entirely possible
I also hear that the computers name was HAL
The door lock appears to have worked as designed.
E.g., locked-out pilot punches in unlock code. Alarm sounds in cockpit. Annoyed co-pilot reaches with his left hand and flicks the switch to LOCK, extending the unlock time by at least five minutes.
Watch the training video: https://www.youtube.com/watch?v=ROIH3KCEIvs. Focus on "door opening logic". BTW, all pursers should look like Sally.
