Stockton Rush, the CEO of OceanGate Expeditions whose submarine imploded during a trip to see the wreckage of the Titanic, once described the glue holding the vessel together as similar to "peanut butter."
News of the sub dominated headlines for days last month after the vessel went missing during its dive to the remnants of the Titanic. Ultimately all five individuals onboard, including Mr Rush, died when the pressure of the deep ocean caused it to implode.
