It may be grand wording, but I hope an improvement over many posts which infer understanding via blame, and thus it won’t happen to them, but without actually understanding how or why.
So whilst stating the obvious “… should have seen …”, "… why didn’t they…” can be self-gratifying, it does nothing to improve safety.
In order to avoid these types of incidents and similar events resulting in accidents, the industry has to put aside error, blame, culture, etc, in search of 'cause'; instead perhaps look at what goes right, and question why in order to achieve a better understanding so that individuals and operators can experience more of what goes right.
