Inappropriate crew response, or not, seems to be the prime subject here.
I might agree with this but I would instead place the shoe on another horse
i.e. inappropriate judgements by untrained PPruners.
For all we know the pilots might have been aware of the issues in the video just above and controlled the flight and vibration accordingly. Yet many are second guessing their assessments of the symptoms available to them in the conduct of obtaining safe flight and landing.
