Pinging you to post 1273.
Unfortunately, that website consistently (check their other articles) takes one or two unrelated items of fact -- and extrapolates into fantasyland.
This one takes the fact that personal submarines exist (photos-- sans links) and the"reported 'fact' that Ghislane Maxwell is licensed to pilot "submersibles" -- and poofs it up into a theory that LSJI was supplied with kids via submarine. And, that is "supported" by a fact-free, un-sourced sketch...
...that I'd be ashamed to publish as a "speculative first draft" -- because it bears zero resemblance to topographic reality...
Anyhoo, thanQ for the link -- if only for an excellent negative example! '-)
