All flight data from the Air France jet that crashed into the Atlantic in 2009 has been preserved in the plane’s retrieved black box recorders, French aviation authorities said on Monday.

The BEA air safety agency probing the crash of the Rio to Paris flight, in which all 228 people on board were killed, said it recovered the data from the recorders pulled from the ocean after a nearly two-year search.

“Following operations to open, extract, clean and dry the memory cards from the flight recorders, BEA safety investigators were able to download the data over the weekend,” it said in a statement.

“These downloads gathered all of the data from the flight data recorder, as well as the whole recording of the last two hours of the flight from the cockpit voice recorder.”. . .
