Never-before-seen Titan sub footage has now been released as part of new Netflix documentary and people are in utter shock.

OceanGate submersible disaster is the subject of a new Netflix documentary that delves into the psyche of the expedition company's billionaire 'borderline psychopath' CEO, Stockton Rush.

We'd already heard some hints about Titan, but Netflix has newly announced a release date for the movie, and provided more pointers as to what it'll be about. It'll release on Wednesday, June 11, one week shy of two years to the day that the event took place.

The submersible was operated by American sea tourism and expedition company OceanGate; the Titan went missing for four days while carrying five passengers, including OceanGate CEO Rush. On June 22, debris of the vessel was discovered on the ocean floor.
