New footage from the U.S. Coast Guard shows the widow of OceanGate CEO Stockton Rush hearing a loud bang, believed to be the Titan submersible's implosion, moments before communication was lost. The Discovery Channel's upcoming documentary, "Implosion: The Titanic Sub Disaster," features this previously unseen video, along with Coast Guard investigation details. The documentary will explore the tragedy, missed warning signs, and questions surrounding deep-sea safety. A Netflix documentary, focusing on Rush's ambition, will also be released in 2025.
