The event itself is truly tragic but if we can learn from this incident and stop similar accidents in the future then it is something we should all benefit from as pilots.
The biggest complaint I have is that this type of investigation could take three or four years for completion and result. This is three or four years that people have to forget about the incident, the new people joining aviation won't know about what happened and so on.
Old news is bad news so the only way pilots can benefit in situations like this is to have a speedy release of factual information and at least keep it in our minds reminding us of the dangers at we CAN be exposed to every time we go flying
