Malaysia missing plane: Robotic sub continues search | |
(about 5 hours later) | |
A robotic submarine has continued its search for the missing Malaysia Airlines flight on the seabed of the southern Indian Ocean. | |
The mini-sub was deployed late on Tuesday, but was forced to resurface due to a technical issue, officials said. It has since been redeployed. | |
The data downloaded from the mini-sub on Wednesday had "no significant detections", Australian officials add. | |
Flight MH370 went missing on 8 March with 239 people on board. | |
Air traffic controllers lost contact with it over the South China Sea while it was en route from Kuala Lumpur to Beijing. | |
Based on satellite data, officials believe it ended its flight thousands of kilometres off course, in seas west of the Australian city of Perth. | Based on satellite data, officials believe it ended its flight thousands of kilometres off course, in seas west of the Australian city of Perth. |
However, so far not a single piece of debris from the jet has been found. | However, so far not a single piece of debris from the jet has been found. |

On Monday, the US Navy's Bluefin-21 robotic submarine was sent on its first mission to search the sea floor for wreckage after signals believed to be consistent with "black box" flight recorders were detected. | On Monday, the US Navy's Bluefin-21 robotic submarine was sent on its first mission to search the sea floor for wreckage after signals believed to be consistent with "black box" flight recorders were detected. |
But the drone exceeded its operating limit of 4,500m (15,000ft) and built-in safety features returned it to the surface. "No objects of interest were found," Australia's Joint Agency Co-ordination Centre (JACC) said. | |
The mini-sub was again deployed on Tuesday from the Australian Defence Vessel Ocean Shield. | |
It was forced to resurface on Wednesday morning to rectify an unspecified technical issue and redeployed, JACC said. | |
"Initial analysis of the data downloaded this morning indicates no significant detections," it said. | |

Some 11 military planes and three civilian planes were also flying out of Perth on Wednesday to scour the Indian Ocean for floating debris. | Some 11 military planes and three civilian planes were also flying out of Perth on Wednesday to scour the Indian Ocean for floating debris. |
Isolated showers are forecast in the search area with sea swells of up to 2m. | Isolated showers are forecast in the search area with sea swells of up to 2m. |
In another development, officials are investigating an oil slick about 5.5km (3.4 miles) from the area where the last underwater signals were detected. | In another development, officials are investigating an oil slick about 5.5km (3.4 miles) from the area where the last underwater signals were detected. |
An oil sample has been sent back to Perth for analysis, a process that will take several days, said Air Chief Marshal Angus Houston, who heads the JACC. | An oil sample has been sent back to Perth for analysis, a process that will take several days, said Air Chief Marshal Angus Houston, who heads the JACC. |

But ACM Houston warned on Monday that the search of the sea floor could be a long, painstaking process that might not yield results. | But ACM Houston warned on Monday that the search of the sea floor could be a long, painstaking process that might not yield results. |
Officials so far have no idea why the plane diverted so far from its intended flight path. Investigators are looking at theories including hijacking, mechanical failure, sabotage and pilot action. | Officials so far have no idea why the plane diverted so far from its intended flight path.
