I recently heard the FO speak about the incident. Here are some relevant aspects of the event from his point of view:
It was soon after sun rise. The sun was low and in their face.
It had recently rained, the runways/taxiways were damp.
There were multiple cloud layers which contributed to a bright glare.
The glare and water made runway lights and marking invisible.
The new, center runway has virtually NO tire marks on it yet.
They had departed KORD at 0600 CST (0400 PST) that's a 0200 PST wake up.
He does not believe fatigue was a factor in his case.
He did not enter the new runway in the FMC.
He did switch LOC freq. but assumed it was still inop when it did not center.
He got tunnel vision and did not look right or left to take in the big picture.
The touchdown was normal and they taxied to the gate.
The Capt. was PF and has well over over a decade with ASA.
The FO has less than 2 years with ASA.
