The disappearance of a submarine last Sunday while on an expedition to observe the remains of the Titanic has the world on edge.

The operation of this type of expedition was in the hands of the OceanGate Expeditions company, which is in charge of the Titan submarine. On the ship were British billionaire Hamish Harding, Pakistani businessman Shahzada Dawood and his son Suleman, as well as Stockton Rush, the company’s CEO, and French submarine operator Paul-Henri Nargeolet.

To take this trip, the company charges $250,000 per seat for its excursions to the famous shipwreck.

Who are the crew members trapped in the missing tourist submarine that was exploring the remains of the Titanic?

One of the most famous travelers the expedition had was Alan Estrada, known for his YouTube channel Alanxelmundo. The Mexican youtuber made the expedition in 2021 and talked about his experience. In the case of his trip, he paid $150,000 and it was the company’s second expedition.

In one of his first videos about the trip, he said they made him sign a liability paperwork stating that the company cannot be sued in the event of a death.

“What scared me was that this is quite a comprehensive release and it contains information that scared me a little bit, under that information it says that I am aware of the dangers of this activity that I do in the expedition that the submarine an experimental submarine,” said.

Just during his expedition, he had three specialists on the ship, one of whom was Nargeolet who had descended more than 30 times to the wreckage of the ship.

In the first expedition, it was not possible to make a successful immersion. “I’d like to be remembered as a pioneering man,” Stockton said in the video.

Due to a problem with a test of the submarine, it was decided to postpone the expedition for a year. In that case, there was a problem with the sonar and take-off system that made it difficult to recover the submarine.

In 2022, the trip could be made and Estrada gave his opinion about the trip, which he did not think was worth paying so much money. He explained that although he tells them the trip is eight hours in total, two to go down and two to go down, so they are out for four hours. However, this is not fulfilled.
