Why is it that when I go to Tesco/ my bank or anywhere else that uses technology, I do not automatically insist/expect an indepth update, the minute said technology throws a wobbler.
Onboard an aeroplane, everyone is an instant expert. You only have to position down the back incognito to hear some of the funniest comments ever.
I think I can speak for virtually all PROFESSIONAL pilots when I say that we react to each situation seriously and we do not put ourselves at risk (never mind the people down the back) If your flight crew had assessed the situation and elected to continue, then that, in all probability would have been the best course of action.
Believe me, even a minor problem can occupy ones thoughts for an hour easily, perhaps that is why there was no PA. Or perhaps the flight deck didn't think one was needed. It is a nicety but certainly not essential.
