Having spent many years in the Navy I can say that for a large percentage of enlisted it is true. Especially for the enlisted they seem to be concentrating on - E-3 and below who either didn't go to A school or who went with one of the less technical specialties. They haven't had any electronics techs. No reactor engineers. No operations specialists or intelligence specialists. None of the ratings that the better educated recruits would gravitate towards. The background for a lot of these would be a whole lot different than the flight deck folks.
I had to cut my viewing short last night. Did they find that guy who went overboard off the Princeton?
Sadly, no.
I found this article about the missing sailor:
