Sounds to me like there are a lot of people here who are due...
. I worry about some of the "never happen to me" attitudes, as they can lead to a complacency that could really cause a problem.
One of the reasons for the redundancy of safety rules and procedures is so that if there is a failure somewhere in the process, as I have had, everyone should still come out safe (as in my case, thankfully). Those who have had (or even just witnessed) ND's generally pay more attention and really rely and preach those redundancies in the future.
