This flight (L9-111) departs about 1630 local – daytime – surely at least one of the pilots must have looked out of the window at lineup and said, or thought, "that looks a bit short"? Or is everything "heads-down" these days?
Although of course I've no evidence, I do wonder if there was bit of non-CRM taking place, rather like Tenerife but without the disaster. Junior co-pilot: "Aren't we headng the wrong way?" Captain with press-on-itis: "No, no, let's get out of here."
