Yes, the Nigel screwed up but that is not the real issue.
The intersection concerned is a known hazard which should have been changed at least 20 years ago but nobody bothered.
The layout of the intersection was a trap waiting for another (yes, several others have done it) unwary pilot to get suckered into on a dark night.
It could have been any of us, it had to happen again eventually and this time it caught a widebody with wings long enough to hit the building.
