Assigning blame is a hindrance to safety, whereas identifying the specific causal and contributory factors of a crash is necessary to prevent recurrence.

“I always point out that what I learned at the NTSB is you can have safety or you can have blame you know if you want to blame people or that's not going to get you to the safety the safety part is identifying the causal and contributory factors and then intervene so those things don't happen again”
