Titanic Tragedy: A Request to Explore the Ocean Again.

The co-founder of OceanGate, the company that owned the Titan submersible, spoke at a Coast Guard hearing. He said he hoped the tragedy would encourage more people to explore the deepest parts of the ocean.

Guillermo Sohnlein, who helped start OceanGate, said the company wanted to build a fleet of submersibles. These submersibles would be able to take people very deep underwater without needing a big support ship.

Sohnlein explained that OceanGate chose to use carbon fiber for the Titan because it was light and less expensive. He said using carbon fiber wasn't a new idea and that other people had considered it before.

However, other people who worked at OceanGate said the company had financial problems and might have cut corners on safety. They said OceanGate was focused on making money and rushed to get the Titan in the water.

The Coast Guard is still investigating what caused the Titan to implode and will be hearing from more witnesses. The tragedy has made people question the safety of private underwater exploration.
