What Caused a Plane to Fall From the Sky in Brazil?

Brazilian investigators are analyzing the black boxes from a São Paulo-bound flight to determine the cause of the crash that killed all 62 people on board. Aviation experts who viewed videos of the incident believe that the plane stalled, causing it to lose lift and ultimately crash. The videos show the plane spinning as it fell from 17,000 feet before crashing on its belly. Experts state that stalling is the likely reason for the spin.
