Suprised no-one commenting about the visual (directed red light) cue not picked up by the crew.
It would be interesting to work out how many steady red lights there are within the airport perimeter. Probably in the thousands.
Might have worked in the old days of signal squares, grass strips, Verey Pistols and two-storey towers next to them but with multiple miles-long runways and huge buildings, towers can be way off where you’re looking when on short finals.
