PERTH, Australia - A mini-submarine making its second dive in the hunt for Malaysian jet MH370 encountered a "technical difficulty" and resurfaced Wednesday, officials said, after the first mission also aborted.
"The Autonomous Underwater Vehicle, Bluefin-21, was forced to resurface this morning to rectify a technical issue," Australia's Joint Agency Coordination Centre (JACC) said.
"Bluefin-21 was then redeployed and it is currently continuing its underwater search."
Data was downloaded from the unmanned vehicle while on the deck of the Australian vessel Ocean Shield, which has led the search for the Malaysia Airlines Boeing 777 that vanished on March 8 with 239 people aboard.
"Initial analysis of the data downloaded this morning indicates no significant detections," JACC said.
