PERTH, Australia - A mini-sub searching for missing Flight MH370 was again sweeping the Indian Ocean seabed Wednesday after aborting its first mission, officials said.
The unmanned submarine equipped with sonar gear was deployed Tuesday night after data analysis of the first failed foray drew a blank, Australia's Joint Agency Coordination Centre said.
After more than three weeks of hunting for black box signals, the autonomous sub had been deployed for the first time on Monday night from the Australian ship Ocean Shield, which has spearheaded the hunt for the Boeing 777 that vanished on March 8 with 239 people aboard.
"The autonomous underwater vehicle was again deployed last night (Tuesday) from ADV (Australian Defence Vessel) Ocean Shield," JACC said.
"The data from Bluefin-21's first mission has been downloaded and analysed. No objects of interest were found," JACC said.
