The company that owns a submersible that imploded on its way to explore the wreck of the Titanic says it has suspended operations.

The U.S. Coast Guard said Sunday it is leading an investigation into the loss of the Titan submersible that was carrying five people to the Titanic, to determine what caused it to implode.

The wrecks of the Titanic and the Titan sit on the ocean floor, separated by 1,600 feet and 111 years of history.

Talk to someone who went on previous trips on the Titan submersible and they’re likely to mention a technology glitch.

The Transportation Safety Board of Canada says it is investigating into the loss of the Titan submersible and has been speaking with those who traveled on Titan’s mothership, the Polar Prince.

The Titan submersible suffered a catastrophic implosion that experts say likely killed its pilot and four passengers instantly amid intense pressure in the North Atlantic’s deep waters.

The deadly implosion of the Titan submersible raises questions about whether the vessel exploring the Titanic wreckage was destined for its own disaster because of its unconventional design and its creator’s refusal to submit to safety checks that are standard in the industry.

The fatal implosion of the Titan submersible has drawn attention to the murkily regulated waters of deep-sea exploration.

Documents show the company whose submersible vanished in the North Atlantic on a tourist dive to the wreck of the Titanic was repeatedly warned that there might be catastrophic safety problems posed by the way the vessel was developed.

In a race against the clock on the high seas, an expanding international armada of ships and airplanes is searching for a submersible that vanished in the North Atlantic while taking five people down to the wreck of the Titanic.

A search is underway for a missing submersible that carries people to view the wreckage of the Titanic.

The around-the-clock search for the missing Titan submersible engrossed the world for days.

An undersea exploration company plans to dive to the sunken Titanic to begin what’s expected to be an annual chronicling of the shipwreck’s deterioration.
