Thanks, yes, I've heard that NTSB crash reports are mind blowing in their attention to detail. A follow on question: how do they ensure people honestly answer questions, is the person not inviting personal liability by answering?

In my experience there has always been a _deep_ culture of mutual respect between industrial aviation players and the NTSB.

Everyone knows that the investigative body is there to help figure out what went wrong and to provide guidance on how to avoid similar mistakes in the future. It’s not about assigning blame, and there’s an understanding that if it were to become about that then the industry would be worse-off as a whole.

(Slightly off-topic, but this is precisely why Tesla’s reaction to the NTSB investigation in their Model X crash was so concerning. Any player that defects here runs the risk of poisoning the process for everyone else.)

Look at the original metal fatigue investigations that lead to round windows.

They pressurized and depressurized an airplane (inside of a water tank) 50,000 times until it failed.
