From the beginning, I have wondered about the remark that, "we have the runway in sight" and have considered that in poor vis, the captain was looking left-rear at one of the north-south streets, perhaps "Abdul Rashead Rd", for example. It's not as though it would be the first time a highway was mistaken for a runway at some distance in poor vis. I am well aware this requires other procedural failures, but given the distance north, had they not already occurred? I wouldn't suggest this as what happened of course, but the question must be eventually asked if only to be eliminated.
Excellent analysis!!
