How are you sure the left engine was shut down?
External videos seem to show, that the landing lights are ON, the beacon is ON etc.
In the latest video in my previous post it sure seems the LH engine is running because you can hear what I think is an engine. Also if the onboard entertainment system is still operational, would you not need AC power on the aircraft? Could it be the APU is running?
In any case, if there is any AC power on the aircraft, why were the interior lights not turned ON?
