Coast Guard releases haunting recording that appears to be Titanic submersible implosion

A recording released by the federal government appears to include audio of the implosion of the experimental submersible that went missing on its way to the wreck of the Titanic.

A National Oceanic and Atmospheric Administration passive acoustic recorder located about 900 miles (1,448 kilometers) away from the implosion site picked up the sound, U.S. Coast Guard officials said in a statement.

The recording became public on Feb. 7.

The brief, staticky recording includes a loud noise that sounds somewhat like an underwater thunderclap. It then goes silent for its remaining few seconds.

The Coast Guard said in a statement that the audio clip “records the suspected acoustic signature of the Titan submersible implosion” on June 18, 2023, the day the submersible went missing.
