No, it just emphasizes that visual lookouts should be on duty and alert at all times.
Murpy’s Law ALWAYS applies.
These incidents have all occurred during calm times, even if at night.
Command was not doing what it should.
I agree but just posed the question. There is always the need for visual outlooks. Just like in the Army, we had the Fire Guard routine in the barracks. But now we have to review what and if any of the old lookout routines were eliminated because someone felt just too comfortable with technology. On its face, this tends to look more and more like a failure in the entire chain of command from the Pentagon on procedure.
