The Coast Guard released a chilling audio recording Tuesday of the implosion of the Titan submersible vessel just hours after it lost contact with a support vessel in the North Atlantic in 2023.

The 23-second audio clip, recorded by a NOAA passive acoustic recorder approximately 900 miles from the implosion site, opens with six seconds of soft white noise followed by a low rumble reminiscent of a distant thunder clap before returning to ambient noise.

The clip went viral shortly after release and has gained audiences from around the world through social media and traditional media outlets from the Associated Press to TMZ.com, E! News and the Hindustan Times in Delhi, India.

A Coast Guard spokesperson in Washington said the Titan Marine Board of Investigation (MBI) released the audio as part of its ongoing investigation into the June 18, 2023, incident. Federal law requires that such evidence be made public unless protected from disclosure under the Freedom of Information Act.
