Guys can we knock this on the head.
Holbrook was clear of the fogbank. Everybody else was either in fog or just outside the fogbank. If you found another 1000 witnesses you would come up with 1000 differing opinions.
Negligence was claimed at Waypoint change. The only person near the aircraft at that point was Holbook.
We can make and educated guess that, like Holbrook, the crew would have been able the see the lighthouse area.
What they could see a few seconds later and why they went there in the first place, I have no idea.
