Single pilot German copilot in control confirmed at live press conference, inclusive actioning descent voluntarily.
Captain requests access after returning from the toilet. No answer from PF.
Completely normal breathing is heard from cockpit till the end.
No comms with Marseille, nor reply to Squawk 7700 request. Other planes also fail to make contact.
Alarms are heard, followed by attempts heard to force the door.
Just before the final impact there is another bang possibly hitting a ridge.
No Mayday was ever sent out, nor was any response given to attempt at radio communications.
He had no reason to initiate the descent, no reason to refuse entry to the captain, no reason to refuse the comms.
What a sad day.
