Indonesian naval divers recovered a flight data recorder from the bottom of the Java Sea, where a Sriwijaya Air jet crashed over the weekend.

Sriwijaya Air flight SJ 182 was on its way from Jakarta, the country’s capital, to Pontianak with 62 people, including 10 children on board, according to rescue workers. The last time that the plane made contact was at 2:40 p.m. local time on Saturday. The plane dipped more than 10,000 feet in one minute after departing from Jakarta and is thought to have crashed off the island of Java, according to Flightradar24.
