I find it funny when people write this off a psychosomatic. I find it similarly funny when people claim a conspiracy<p>I find the skeptical view that it would have to be some crazy science fiction "sick ray" kind of childish. The CIA literally had a "heart attack gun", and it was just a dumb dart gun with some drugs. It's easy to make simple technology sound wild and interesting and impossible. A weapon of this kind would either be very simple, or not. If it's an EM based weapon, there aren't a lot of dials to turn, so either there is a power/frequency combo that causes these effects, or not.<p>Likewise, I find the conspiratorial view that it definitely happened and there is some kind of cover up to hide either the weapon or some conflict pretty ridiculous. Partially for the same reasons outlined above (a weapon like this wouldn't be very interesting IMO), and partially because it took place in Cuba. Its obviously a somewhat adversarial nation. Something like this would normally be a news story for a week, if at all, then maybe be a footnote in some history books at most.
