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.
