Turbulence, faulty instrument readings and a stalled engine. That could be the deadly combination of factors that caused Air France Flight 447 to crash en route from Brazil to Paris in June 2009. All 228 passengers and crew on board were killed. This new information comes from the black boxes of the plane's wreckage, recovered from the bottom of the Atlantic earlier this month.
