Rat 5,
That is a very good point, United looked to be about 45 to the flightpath, so the pax got a real good view, the other acs, especially #2, had a very, very good view of an ac less than 50 feet above them, heading to the windscreen...damn, that must have been quite the experience.
Funny how it is always the lowest common denominator that exposes the weaknesses in a system.
Many discussions in the ATM circles on this with the move to automation of towers and remote towers. Especially how worthless ADSB is on final.
