I know that everyone is tired of hearing my airframe design stories, but it's 
obvious to me that few engineers understand the principles of failsafe design. 
This article makes that abundantly clear - and the consequences of paying no 
attention to it.

You can add in Fukishima and Deepwater Horizon as more costly examples of 
ignorance of basic failsafe design principles.

Yeah, I feel strongly about this.
