A closer Look at The Missing Sub And Rescuers

The search for a missing Titanic tourist submersible continued Wednesday as experts feared the watercraft may have only a day's supply of oxygen left.

U.S. and Canadian crews began searching for the vessel Sunday after the 22-foot submersible, Titan, lost contact with a support ship while carrying five people to the wreckage site of the Titanic.

Here’s a closer look at the Titan submersible owned by OceanGate, a Washington-based deep-sea exploration company.
