"You can't see the wingtips from the cockpit".
You can't see the wingtips from the cockpit of a DC-10 either but I was lucky enough not to scrape one far less destroying a building.
The point surely has to be that something distracted this crew, either internally or externally, otherwise this would not have happened.
In any case, how can you explain how a BA 744 captain managed to severely modify my PA-28 on a CAVOK day with both wingtips clearly in sight and no ACARS fitted?
I am fairly confident that a distraction was involved.
