The tower is charted and properly lighted. One can break the chain by
practicing good airmanship.


I think you miss the point of the "accident chain."


I don't think so.



The point is that
mini chains form all the time, and you need to work on ALL the
potential links to avoid accidents, rather than picking one and saying
this is the one that I'm going to rely on to avoid accidents.


It appears the link that was broken was making themselves aware of the
tower.
