The submersible is named Titan, reminding us of Futility, Wreck of the Titan, the book published in 1898, which foretold what would happen to the Titanic on April 14-15, 1912.

Notice, the Titan disappeared on Sunday, June 18, 2023, 86 days after Morgan Robertson’s death anniversary, and we know 86 is a number of death and “getting rid of.”
Human Sacrifice = 86
Blood Sacrifice = 86

As for the five people that are missing, the one who is getting the attention in the media is 58-year-old Hamish Harding, who has disappeared just shy of his 59th birthday, June 24, 2023. Of course, that is Freemasonry’s birthday.
Freemasonry = 58 & 59

And for one last point, the news of the disappearance broke on the 19th of June.
Titan = 19
