Yeah the asbestos thing....This seems to me to resemble the background radiation as opposed to toxic level exposure, regarding fiber length and dose...In other words a certain amount of fiber exposure is omnipresent and tolerated...So it would seem an approach such as 10μm banned, 6-9μm special controlled, 5μm and under precautions....would be acceptable but perhaps problematic in regulation...but possible...

Why this guy feels guilty is not apparent, I'm not sure we have all the facts...

He wasn't the only one. It's really too bad that he felt so responsible; he, and others really made an effort to prevent the catastrophe.

This has been in the news lately. He has received many supporting letters, and according to the most recent reports, they have helped to put his mind more at ease about that event.

What happened to the people responsible for going ahead with the launch. Arrested, charged, demoted, fired, or given a bonus?
