A pilot's chilling final words have been revealed as his plane crashed into the Atlantic Ocean, claiming the lives of all 228 people on board.
Doomed Air France Flight 447 was travelling from Rio de Janeiro to Paris but plunged into the sea just four hours after take off on June 1, 2009.
Five British citizens were among the victims.
In took investigators two years to recover the plane wreckage and black box - found in its entirety at the bottom of the ocean, about 620 miles off Brazil's north-east coast.
In what is Air France' s deadliest disaster to date, France's Bureau of Enquiry and Analysis for Civil Aviation Safety (BEA) concluded that ice crystals had caused the autopilot to suddenly disconnect mid-flight, the Daily Star reports.
Then the crew's reactions to the fault caused the aircraft to enter an aerodynamic stall.
The tragedy of 228 deaths was a combination of technical failure and the pilots' inability to react to the plane stalling, which sent it falling into the Atlantic Ocean at a terrifying speed of 11,000ft (3,352m) per minute.
The pilots were left confused by a fault to the air-speed readings but then made the crucial mistake of pointing the nose of the plane upwards when it stalled instead of down.
Investigators recovered a recording from the cockpit in which first officer, co-pilot Pierre-Cédric Bonin, 32, could be heard swearing before admitting "[I] don't have control of the airplane any more now", and two seconds later, "I don't have control of the airplane at all!"
David Robert, 37, the flight's relief first officer, co-pilot replied: "controls to the left," before taking over control of the aircraft and pushing his side-stick forward to lower the nose and recover from the stall.
Bonin however, was still pulling his side-stick back which meant the inputs cancelled each other out and triggered an audible "dual input" warning.
The captain, 58-year-old Marc Dubois re-entered the cockpit after being summoned by Robert. With various alarms going off, he asked the pair: "Er what are you [doing]?"
Robert told Captain Dubois: "We've lost all control of the aeroplane, we don’t understand anything, we've tried everything".
Robert can be heard saying to himself: "Climb, climb, climb, climb."
Bonin replied: "But I've been at maximum nose-up for a while!"
Mortified Dubois realised Bonin was causing the stall, and yelled: "No no no, don't climb! No No No!"
Bonin temporarily gave the controls to Robert but the aircraft was too low to recover from the stall, and a ground proximity warning system sounded an alarm ahead of their imminent crash into the ocean.
Bonin reacted by pulling his side-stick all the way back again, and swore before screaming: "We're going to crash! This can't be true. But what's happening?"
The last recording on the CVR was Dubois saying: "(ten) degrees pitch attitude."
