Bangkok |An Indonesian navy diving team retrieved one of the flight recorders from Lion Air Flight 610 from the depths of the Java Sea on Thursday, raising hopes that investigators will be able to solve the mystery of what led a brand-new Boeing jet to fall from the sky this week.

The team located the device at a depth of around 30 metres in waters northeast of the Indonesian capital, Jakarta. On Wednesday, search teams heard pings from a beacon attached to the data recorder, but strong ocean currents stopped them from recovering the device.
