Officials are still searching for a civilian submersible with five people aboard after it went missing in the North Atlantic while voyaging to the wreckage of the Titanic. The founder of OceanGate, the company that organizes Titanic expeditions, showed a CBS team the inside of the type of submersible used for the tours. CNN's Gabe Cohen, who also went inside a similar OceanGate vessel in 2018 when reporting for KOMO, explains what surprised him most about how the vehicle operates.#cnn #news #titanic #submarine
