A visual approach at night is no laughing matter.
Flying one into SFO due to all the local aural and visual chatter does not make it easier.
And then they were tired and/or became a bit complacent and were then way behind in setting up the airplane (i.e. putting the correct ILS app into the FMS, as soon as the ATIS said so, etc.) and being on the same page as a crew.
It has happened to all of us in one way or the other - the sudden question: "WTF? How did I get here?!"
BUT - they figured out they were wrong and went around - Problem solved.
That - does not happen to all of us.
