A big issue in the search for the submersible that went missing during an expedition to the wreckage of the Titanic is just how deep that wreckage sits. It’s around 13,000 feet below sea level, and a retired Navy captain with three decades of experience including salvage operations tells CNN, «There’s very few assets in the world that can go down that deep.» Even sophisticated naval craft can only dive about 1,000 feet per hour, meaning if the sub is close to the wreckage, getting to it and surfacing again could take an entire day. On such a journey, a remote craft wouldn’t be able to search along the ocean floor once it got there: «When you’re going deep, you usually go up and down like an elevator,» the expert says.
