I have just had a discussion (??) with my wife, that I lost as usual, as to the reasons why the cabin crew/flight deck could not communicate over the PA system as to what the problem was.
She would not accept that the crew were carrying out procedures to ensure the passengers were safe which included going down through the cabin to ensure the more elderly, infirm or very young ones were cared for, or bringing the aircraft to a more acceptable altitude.
To her, everything should have waited until an announcement to calm the passengers had been made
