All very amusing until one crew crashed and several had to be rescused by the PM. If we re-ran this incident as a sim scenario I wonder how many crews would perform as well as this one ?
Didn't this happen for real in South America a few years ago? It was dark, intermittent connection on the attitude indicator(s) and they flipped the plane over. I thought that was a design fault as well, if one of your instruments loses its input signal you don't want it to just freeze, you want it to clearly tell you that it's not to be trusted so you can try something else.
