Lots of waffle on this thread. There is one cardinal rule that you should never break. You must never, ever, land on an occupied runway....period. It's that simple. A 737 as far as I know still has windows that enable you to look out and see aircraft on the runway, and those flappy things near the wingtips enable you to turn and avoid other airborne traffic......I think they are called ailerons.
yes I'm being facetious, but to think that a crew would land on an occupied runway, rather than a simple go around for traffic that is tracking roughly 90 deg to the centreline and getting further away, it would have only required a 10 deg heading change to the left.......no problem. It beggars belief that an airline captain would continue the landing.
