JAKARTA, Indonesia (AP) Divers on Thursday recovered a flight recorder from the crashed Lion Air jet on the seafloor , a crucial development in the investigation into what caused the 2-month-old plane to plunge into Indonesian seas earlier this week, killing all 189 people on board.

One TV station showed footage of two divers after they surfaced, swimming to an inflatable vessel and placing the bright orange device into a large container that was transferred to a search-and-rescue ship.

I was desperate because the current below was strong but I am confident of the tools given to me, said navy 1st Sgt. Hendra, who uses a single name, in a television interview. After narrowing the possible location, I started digging and cleaning the debris until I finally found an orange object, he said, standing on the deck of a ship next to his diving mate.
