PASSENGER ON 2021 DIVE TO TITANIC DESCRIBES RISKS

Looking back on his own 2021 dive to the Titanic, an early OceanGate passenger says one must be “a little bit crazy.”

Arthur Loibl, a retired businessman and adventurer from Germany, told The Associated Press on Wednesday that he conceived the idea to see the Titanic while on a 2016 trip to the South Pole. He paid $110,000 for a dive in 2019, but the first submersible didn’t survive testing. Loibl went two years later.

“Imagine a metal tube, a few meters long with a sheet of metal for a floor. You can’t stand, you can’t kneel. Everyone is sitting close to or on top of each other,” Loibl said. “You can’t be claustrophobic.”

The dive, which was repeatedly delayed to fix problems, took 10 1/2 hours, he said.

Lost aboard the vessel are pilot Stockton Rush, the CEO of the company leading the expedition. His passengers are a British adventurer, two members of a Pakistani business family and a Titanic expert.

“I was a bit naive, looking back now,” said Loibl.

COAST GUARD BRINGS IN MORE SHIPS FOR SEARCH

The Coast Guard says it is bringing in more ships and underwater vessels to search for a submersible missing in the North Atlantic after underwater sounds were detected, providing a glimmer of hope three days after the Titan disappeared while taking five people down to the wreck of the Titanic.

Although the exact location and source of the sounds were not yet determined, they allowed searchers to focus on a more narrowly defined area. The full scope of the search was twice the size of Connecticut and 2 1/2 miles (4 kilometers) deep, said Capt. Jamie Frederick of the First Coast Guard District.

“This is a search and rescue mission, 100%,” Frederick said. “When you’re in the middle of a search and rescue case, you always have hope.”

But even those who expressed some optimism warned that many obstacles remain: from pinpointing the vessel’s location, to reaching it with rescue equipment, to bringing it to the surface — assuming it’s still intact — before the passengers’ oxygen supply runs out.

The U.S. Coast Guard did not elaborate on what rescuers believe the noises could be. The vessel hasn’t been heard from since Sunday. The passengers are estimated to have as little as a day’s worth of oxygen left.
