I am with blunderbus....i heard the atc video, my take is they just didnt arm loc...doesnt matter visual, tired or any other bs blah blah excuse. United should get a kick in the ass for ignoring a RA.
The brief for sfo is high threat close parallel ops....i.e dont fly thru the runway....jesus just try seattle with 3 runways and they cross you high across two northern runways and then ditch you capture from above maintain visual separation.....”u visual cathay?”......
