The Indonesian National Search and Rescue Agency says it has retrieved one of the black boxes from Lion Air flight that crashed into the Java Sea on Monday, with 189 people aboard.
The search team used a so-called "ping detector" to detect signals from the black box, and used a remotely operated underwater vehicle to retrieve it
The box is crucial to answering why the brand new Boeing aircraft could crash in clear weather.
Earlier reports of the fuselage being found have now proven to be false.
Searchers have confirmed that a 20-metre-long object turned out to be a shipwreck.
