I'd like to think the aircrew would as well given they are all told about each other.
I doubt it. When I'm doing your own control OCTA and I am high alert for this, I'm ready for it (and there is no way I would allow that MEL scenario to develop out in the sticks). But I'm in a CTR under positive ATC control at less than 1500ft on final, considering how I might extricate myself if I do a simultaneous go around with an aeroplane I probably can't see is fairly low down on the priority list, especially at night.
In my view, ATC
must build in decent lateral separation/stagger for these types of LAHSOs.
