I don’t know where this discussion is going, so let’s get back to the subject.
Firstly, just because the US Navy has suffered two mishaps doesn’t mean that the service is full of blithering idiots. They are in fact professionals of great ability and I am sure they will quickly work out the problem of improving bridge watchkeeping standards of Junior officers.
Secondly, the merchant marine also went through a very stressful period of ship losses in the 90s which was sorted out by bringing in a strict code of safety management.
Thirdly NASA had its own share of mishaps which too was tackled through better safety systems.
None of us in this forum is a fount of great knowledge and ability. We have all made our share of stupid mistakes that we don’t want the world to know.
