Another technique is to get a diver to bolt on (or otherwise attach) a container full of drugs to the hull of some regularly scheduled cargo ship and use another diver to detach it when it arrives at the destination.
The distance between the subs they have now, and the type described in the post I replied to is the distance between a Model T and a Ferrari LaFerrari.
Rocket scientists are well educated. There are lots of smart people who aren't. Generally speaking most people are smart. What one believes about other people's intelligence says more about the believer's intelligence than the believee's.
The drug dealing world is resourceful. I would be shocked to the point of incredulity if the primary obstacle to implementing basic improvements casually mentioned in HN comments was simply that they didn't have anyone they could consult on the matter.
They're not going to be developing in-house nuclear weaponry, no, but cartels can and do find intelligent, experienced and competent people who can help optimize their supply chains.
I don't think it's a matter of them not realizing there are superior designs; I think it's a matter of superior designs not being worth the extra cost or somehow having an unintended result.
Resourceful only gets you so far... at some point you need a team of engineers with stable jobs over a long period of time. I'd say the line is roughly between the junky subs we see now, and researching, developing and fielding a stealthy modern sub. It's not impossible, but it's not like finding a chemist who can teach a whole bunch of people who to follow a recipe. You're talking about specialized skills, and people who have those skills and have put them into practice tend to be watched.
You're not going to find a specialist in "Whole sub designs and manufacture" anymore than you could kidnap one person who would teach you how to build the space shuttle. You'd need to kidnap teams of specialists, which I would assume might draw international attention.
Insane. I don't doubt that legalizing drugs would have relatively short-term impacts as some people who would have otherwise never tried them, try them, and some of those become hooked. How anyone can look at that, and compare it to the insane and eternal war we've chosen instead, and find the war a better choice is baffling to me.
No but thankfully rocket scientists have publicly demonstrated that it works, and car manufacturers ensure the parts are available worldwide at rock bottom prices (with native language schematics and instructions!).
I suspect they don't gain any tangible benefit from firing further.
