Titan and the banging in the deep
OceanGate's submersible Titan lost contact on 18 June 2023 during a dive to the Titanic with five people aboard; for four days the world followed a search in which aircraft sonar picked up 'banging' sounds.

The account
A Canadian CP-140 Aurora recorded underwater noises, and the US Coast Guard said their source was unknown. Hopes that the occupants were knocking on the hull kept the story alive as the oxygen countdown ran. On 22 June a remotely operated vehicle found the debris about 500 m from Titanic's bow; the US Navy had detected an acoustic signature consistent with an implosion soon after contact was lost.
The sceptical view
The implosion happened on the first day; the noises came from other sources in a noisy ocean.
