The report said the pilot sent a manual signal at 11 p.m. local time saying he was flying through an area of ?CBs? black, electrically charged cumulo-nimbus clouds that come with violent winds and lightning. Satellite data has shown that towering thunderheads were sending 160 km/h updrafts into the jet?s flight path at that time.
Ten minutes later, the plane sent a burst of automatic messages, indicating the autopilot had disengaged, the ?fly-by-wire? computer system had been switched to alternative power, and controls needed to keep the plane stable had been damaged. An alarm also sounded, indicating the deterioration of flight systems, according to the report.
Three minutes after that, more automatic messages indicated the failure of two other fundamental systems pilots use to monitor air speed, altitude and direction. Then, a cascade of other electrical failures in systems that control the main flight computer and wing spoilers.
The report repeats a detail previously released by Brazil?s Air Force: that the last message came at 11:14 p.m., indicating loss of air pressure and electrical failure. The newspaper said this could mean sudden de-pressurization, or that the plane was already plunging into the ocean.

Brazilian officials say debris they thought was from an Air France crash in the Atlantic was in fact sea "trash", adding to the uncertainties surrounding the jet tragedy.
"Up to now, no material from the plane has been recovered," Brigadier Ramon Cardoso, director of Brazilian air traffic control, told reporters in the northeastern city of Recife.
Items, including a cargo pallet and two buoys, pulled from the ocean early Thursday - which Brifadier Cardoso himself had initially said came from downed Air France flight AF 477 - actually came from another source, most certainly a ship.
"We confirm that the pallet found is not part of the debris of the plane. It's a pallet that was in the area, but considered more to be trash," he said.
