Bluefin-21 Search Faces Challenges

In the difficult search for missing Malaysia Flight 370, the Bluefin-21 scans the ocean floor for clues.  But even getting the equipment into the water poses certain challenges.

Wind can dictate what side of the boat the Bluefin-21 is lowered from, fearing that a gust could send the delicate instrument crashing into the side of the boat.

Wave heights and strong currents on the surface of the ocean can also impact the deployment.

Indra Petersons explores these obstacles that searchers face in their efforts.
