2 sheds;
From what was put together from other sources, and not from the NTSB (like you still waiting for the final report.) the way that the runways are lined up (looking at it in the dark) about the soonest the controller could have possibly noticed that the lights weren't going quite in the right direction (nav lights) was about going through the intersection... Probably to late to do anything about it, especially if you think about the time it takes to see something (after working almost a full mid shift.) and then getting to the mike and saying something and for the pilots to comprehend it...
regards
Scott
