Was the vibration level observed in the passenger's video "high", as envisaged by the advice from Boeing?
Or was it "extreme"and way beyond anything they ever considered? ((Not saying it was. Just asking)
And how long did they anticipate that the vibration would last or be tolerated for?
Given that the situation Boeing describes seems to be the exact situation the XAX experienced (fan blade separation) I'd suggest that this is the "severe" vibration they mention.
Mind you, there may be a difference in the levels of vibration experienced by a Boeing compared to an Airbus in the same scenario but I can't imagine an Airbus would be much more likely to self destruct.
