What kind of "security" are we practicing if this guy can get on board one of our Nuc Carriers and wander for 2 hours?????
All security is concentrating on abortion clinics. No one left to check for real terrorists.
I'll try to shed a little light on port vists and tours aboard carriers. It sounds as though vistors had to gain access to the shipyard in order to gain access to the ship. If that's the case, then it was the duty of the host country, (in this case the Brits), to determine who does or does not gain access to shipyard.
As far as the shipboard tours go, alot of that depends on what country you're in. As a general rule of thumb, countries that are deemed relatively "safe", general visting would be allowed, in effect, the local yokels can visit the ship.
Generally, groups of the locals would be led on guided tours of the ship, at no time would anyone be allowed to roam about on their own. The tours would last 30-45 minutes and they're shuffled off of the boat.
Some ports were more restrictive, the general public could not visit en mass and there weren't any guided tours, crew members, however, could bring locals aboard. Again, no unescorted visitors.
Other ports, only official guests, (local big wigs), would be allowed aboard.
That's more or less how it was on the four carriers I served on, ( two conventional, two nukes), all pre 9-11-2001.
If the ship is pierside, the crowds move fairly quickly. If the ship is anchored out and required boating, the tour cycles took awhile, (the 30-45 minutes of actual tour, waiting for a boat to transport them to & from the ship).
So, if the guy got on the shipyard, had to wait for a boat to get to the ship, take the tour and then wait for the return boat, that could take two hours, easy.
Nonetheless, this guy shouldn't be roaming about anywhere, imho.
