The CEO of OceanGate Expeditions described the glue holding their experimental submersible together as "like peanut butter".
Stockton Rush had made the comparison in a video posted years before his death and the death of four passengers on board the Titan, the submersible that suffered a catastrophic implosion near the wreck of the Titanic.
In the video, he added that the glue was "thicker than Elmer's glue". The video showed Rush overseeing the team of engineers as they assembled the carbon-fibre submersible.
