a few thoughts
white knight...you are a master of understatement...instrument scan remiss!!!!!
in my old prehistoric 737 a radio altitude that low would also enable the thrust reversers, not that this is part of the crash,,but wonder if that is the case with NG.
May I suggest that everyone in the cockpit was trying to be the FIRST to spot the runway? (acquire visually that is) and no one was watching the store. After all, modern planes are fool proof aren't they?
at least one person in the cockpit should be on instruments until DH, or all visual cues are available...and at this point, the pilot flying should report "OUTSIDE, VISUAL REFERENCE" and the NFP should start monitoring the speed and glide slope etc.
