From 900 miles away, the US government recorded audio of the Titan sub implosion
Thanks to being an incompressible medium, water transmits vibrations both farther and faster than the air. (Here's a good video explainer on the subject.) This fact helps to explain how a US government-owned "moored passive acoustic recorder" was able to hear and record the 2023 implosion of the doomed Titan submersible—even though the recorder was 900 miles away from the dive site.
That implosion, during an attempted dive to the wreckage of the Titanic, killed five people, including Stockton Rush, the CEO of the company that built and operated the Titan.
The implosion audio was just released publicly by the US Coast Guard's Titan Marine Board of Investigation, which has been investigating the disaster in enormous detail. As part of that investigation, the Coast Guard obtained the audio from the National Oceanic and Atmospheric Administration (NOAA), part of the US Department of Commerce.
