Mini-sub continues search for plane

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, according to BBC.
