New details surrounding the missing submersible that disappeared on its way to the Titanic continue to emerge, including details of the waiver passengers signed.

Nine’s US correspondent Alison Piotrowski revealed to Chris O’Keefe that the passengers, who reportedly paid $250,000 for the experience, signed waivers that mentioned the risk of death three times on the first page.

Currently, experts believe the passengers onboard the missing submersible have less than 10 hours of oxygen remaining.
