- OceanGate CEO Stockton Rush once compared the glue holding Titan sub's hull together to peanut butter.
- In a 2018 video, he called the glue between the carbon fiber hull and titanium ring "pretty simple."
- Rush and four passengers died in June after the sub imploded during a trip to the Titanic wreck.
OceanGate CEO Stockton Rush once said the glue holding the ill-fated Titan submersible's carbon-fiber hull together was "like peanut butter," calling it thicker than Elmer's glue and "pretty simple."
In a 2018 video on OceanGate's YouTube channel, Rush oversaw the bonding of the Titanic-bound sub's titanium ring and carbon-fiber hull.
He said the glue holding the titanium ring and hull together was "very thick, so it's not like Elmer's glue, it's like peanut butter."
Earlier in the video, Rush acknowledges that the glue was "pretty simple, but if we mess it up, there's not a lot of room for recovery."
Experts and former OceanGate employees warned Rush that the Titan submersible — including its glue and carbon fiber hull — could be dangerous and might collapse under the deep ocean's pressure. Rush previously cited "innovation" as the reason behind the sub's experimental design and why it never checked to see if it met industry standards.
The Titan sub imploded last month during a trip to the wreck of the Titanic, killing all five people aboard, including Rush.
Based on photos of the submersible's wreckage, an expert told Insider that it appears the experimental carbon-fiber hull failed first, resulting in a catastrophic implosion.
