however -the moment the generators trip offline everything goes black. We need to ensure everything else is ready before shutting power off...
Standby/emergency power is still available after after gens go offline. This incident did occur in broad daylight, emergency exit lighting turns on automatically day or night.
If rear slide was deployed/being blown by #1 engine still running and passengerswere using wing slide while still running there was a clear lack of a coordinated evacuation. It should all come out in the investigation and will be interesting to read.
No intent to criticize, just adding info that may be helpful and thankful all were able to survive with only a few reported minor injuries.
