Authorities investigating the implosion of an experimental submersible on its way to the Titanic wreckage in 2023 have released a new video recorded aboard a support ship at a key moment. The Titan vanished on June 18, 2023, setting off a five-day search that ended with authorities saying all five passengers were dead, including the CEO of the company that built the vessel, Stockton Rush.  U.S. Coast Guard investigators last week released a video of Wendy Rush monitoring the Titan that day, hearing a noise that sounds like a door closing and saying, “What was that bang?” The Coast Guard says it believes it was the sound of the Titan’s implosion reaching the surface of the ocean.
