"Needless to say the flight deck and cabin crew were not amused". I find what you have stated as quite alarming. Its obvious that the pax where very worried indeed and whilst we might know what the problem was, an lnfrequent flyer might fear the worst. I suggest you take stock and if you think pax or for that matter crew should keep quite if they suspect a problem just remember the jet out of lhr that came down in staines, again people/crew not saying anything. So are you saying you would keep quite.
