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.

What to know about the missing sub
A submersible on a tour of the Titanic wreckage was reported overdue by its operator OceanGate Expeditions on Sunday, prompting the United States Coast Guard to launch a search and rescue effort for the 22-foot, 23,000-pound vessel.
Designed with life support to sustain five crew members for 96 hours, the submersible would need to be rescued in three days to save its five passengers, according to the Coast Guard.
Stockton Rush founded Washington-based OceanGate in 2009 to make deep-sea exploration more accessible to scientists and tourists. Fourteen years, more than 200 dives and three submersible designs later, the company now finds itself in a desperate search to recover the submersible carrying five people aboard that’s gone missing off the coast of Newfoundland, Canada.
OceanGate confirmed Monday it had lost contact with a submersible, saying in a statement: "We are exploring and mobilizing all options to bring the crew back safely. Our entire focus is on the crewmembers in the submersible and their families. We are working toward the safe return of the crewmembers."
Here's what we know about the submersible.

Former passenger says his sub lost contact with host ship on all 4 trips
Mike Reiss, who has done four, 10-hour dives with OceanGate, including one to the Titanic, told ABC News his sub lost contact with the host ship on every dive.
"Every time they lost communication -- that seems to be just something baked into the system," he said.
With no GPS, Reiss said it took his crew three hours to find the Titanic despite landing just 500 yards from the ship.
Reiss said he signed "a waiver that mentions death three times on the first page.”
"It is always in the back of your head that this is dangerous, and any small problem will turn into a major catastrophe," he said.
He said the submersible is built simply and is "just propelled by two fans on the outside."
"Even I was able to steer and navigate the sub for a while," he noted.
Reiss said his greatest fear was that the sub wouldn’t be able to release the weights that force it to submerge once it was time to rise to the surface.
