Robotic submersibles to help in search for Malaysia Airlines Flight 370

Authorities are hoping to find that physical evidence when the weather improves and the search resumes.

In an exclusive OutFront report, CNN's Rosa Flores got access to a high-tech underwater vehicle, which could help find that critical evidence.
