Missing Titanic submersible live updates: Texts show OceanGate CEO dismissed concerns

Five people, including the company CEO, were aboard the sub when it imploded.

All passengers are believed to be lost after a desperate dayslong search for a submersible carrying five people that vanished while on a tour of the Titanic wreckage off the coast of Newfoundland, Canada.

The 21-foot deep-sea vessel, operated by OceanGate Expeditions, lost contact about an hour and 45 minutes after submerging on Sunday morning with a 96-hour oxygen supply. That amount of breathable air was forecast to run out on Thursday morning, according to the United States Coast Guard, which was coordinating the multinational search and rescue efforts.

US Navy crane in Newfoundland but awaiting ship

A U.S. Navy portable crane system capable of bringing up items from as deep as 20,000 feet has arrived in St. John's, Newfoundland, but is waiting to be welded onto a chartered ship to take it to the search area for the missing submersible, according to a U.S. Navy official.

The Navy has not yet contracted a ship for the salvage system, known as Fly Away Deep Ocean Salvage System or FADOSS, the official told reporters Wednesday. Once the ship is contracted, Navy teams will spend approximately 24 hours working around the clock to weld the system aboard the ship before it can leave port, the official said.

FADOSS is the salvage system the U.S. Navy uses for all of its deep-water recoveries. Last year, it was able to bring up an F/A-18 aircraft that had fallen into the waters of the Mediterranean Sea.

Company behind Titan overstated details of partnerships with Boeing, others

The company behind the submersible that imploded exaggerated the details of the industry partnerships behind the development and engineering of the underwater vessel.

In some public statements, OceanGate suggested the Titan -- its only vessel able to reach Titanic depths -- was designed and engineered with the assistance of entities such as Boeing, the University of Washington and the National Aeronautics and Space Administration. In statements to ABC News, each entity described its role, or lack thereof, as more limited than sometimes stated by OceanGate.

When asked about these exaggerations about the role of partnerships in the development of the Titan submersible, an OceanGate representative declined to comment on the matter.
