The descent lasted 3 minutes and 30 seconds and the engines remained operational, said the report. It plunged at 10,912 feet (3,300 meters) per minute. At the time of the descent, the two co-pilots and captain were in the aircraft cockpit. In tech's golden age, why can't black boxes do more? Ricahrd Quest, CNN's aviation expert, said: "For whatever reason the aircraft speed sensors failed and the A330 went into a high altitude stall.

The pilot's actions were unable to recover the aircraft and some might say, made the bad situation worse. "The actual falling from the sky will have been horrific. This plane fell out of the sky." All 228 people aboard the Airbus A330 Flight 447 from Rio de Janeiro to Paris were killed on June 1, 2009. The pilots lost contact with air traffic controllers while flying across an area of the Atlantic Ocean known for constant bands of severe turbulence. Air crash investigators at the Paris-based BEA have been working on the theory that the speed sensors, known as pitot tubes or probes, malfunctioned because of ice at high altitude. Since the accident, Air France has replaced the pitots on its Airbus fleet with a newer model. The report quotes some of the pilot's conversation -- who were not named -- and reveals that they were aware of the upcoming turbulence and storm.
