Video footage released by the US Coast Guard shows the moment the wife of the late OceanGate CEO Stockton Rush heard the apparent sound of the Titan submersible imploding. In the video, Wendy Rush, a director at the ocean tourism company — which has since suspended all operations — can be seen attempting to contact the sub from the Polar Prince support vessel when a loud slamming sound can be heard through her monitor.

After the OceanGate Expedition submersible imploded in June 2023, new video footage shows when the sound of the collapse reached the surface while the company’s team monitored its descent.
