'What was that bang?': Sound of Titan implosion captured in footage

The infinitesimal disaster deed nan Titan submersible has been captured successful footage recorded connected nan sub's mother ship.

During an expedition to nan Titanic shipwreck that lies 3800 metres beneath nan Atlantic Ocean, nan OceanGate Titan imploded connected June 18, 2023.

The 5 passengers aboard, who included OceanGate's main executive Stockton Rush, were each confirmed dormant pursuing nan find of nan wreckage.

A caller BBC documentary into nan disaster gained entree to worldly from nan US Coast Guard's (USCG) investigation.

Footage obtained by nan USCG shows Wendy Rush, nan woman of Rush, listening to nan sound of nan implosion while watching connected from nan sub's support alloy and asking: "What was that bang?"

She is shown sitting successful beforehand of a machine that was sending and receiving matter messages from Titan astir 90 minutes successful from erstwhile it started its dive.

A sound sounding for illustration a doorway slamming is heard erstwhile nan submersible reaches a extent of 3300 metres, prompting her to look up and inquire different OceanGate unit what nan sound was.

Moments later, Wendy Rush receives a matter connection from nan sub saying it had dropped 2 weights, which apparently caused her to mistakenly judge nan dive was proceeding safely.

But nan USCG says nan sound was successful truth nan sound of Titan imploding.

Officials opportunity nan matter message, which must person been sent conscionable earlier nan sub deed disaster, took longer to scope nan vessel than nan sound of nan implosion.

Stockton Rush and nan 4 different group aboard - businessman Shahzada Dawood and his 19-year-old son, Suleman Dawood; businessman Hamish Harding; and French diver Paul-Henri Nargeolet - died instantly.

Earlier this twelvemonth astatine nan USCG hearings into nan disaster, a damning image of nan Washington-based institution that developed and operated nan submersible arsenic good arsenic its laminitis – who charged passengers astir $US250,000 (nearly $400,000) per dive - emerged from testimonies.

After nan submersible mislaid interaction pinch its mother vessel and grounded to resurface, a melodramatic world hunt and rescue ngo unfolded successful nan distant waters respective 100 kilometres south-east of Newfoundland.

Authorities concluded nan alloy had suffered a "catastrophic implosion," a abrupt inward illness caused by immense pressure.

The USGC investigation has centred connected nan creation of nan Titan, built from c fibre, an different worldly for heavy oversea submersible crafts.

A known problem is that c fibre layers tin abstracted nether pressure, a process called delamination.

USGC investigators judge nan Titan's building showed signs of weakening successful 2022 aft nan trade completed its 80th expedition.

Passengers reported proceeding a large bang arsenic nan sub returned to nan surface.

They were told by Stockton Rush that this sound was nan sub shifting successful its frame.

But nan USCG says nan information collected from sensors fitted to Titan shows that nan bang was caused by delamination.

The US Coast Guard will people a last study bout its investigation later this year.
