The mysterious disappearance of Flight AF 447 over the Atlantic Ocean has fueled speculation among aviation experts about what caused the state-of-the-art airliner to come down.
According to Air France CEO Pierre-Henri Gourgeon, the Airbus A330-200 encountered heavy turbulence about 02:15 a.m. local time Monday (10:15 p.m. ET Sunday), three hours after the jet carrying 228 people left Rio de Janeiro, Brazil, for Paris, France.
At that point, the plane’s automatic system initiated a four-minute exchange of messages to the company’s maintenance computers, indicating “several pieces of aircraft equipment were at fault or had broken down.”
The jet, which was flying at 35,000 feet and at 521 mph, also sent a warning that it had lost pressure, the Brazilian air force said. Its last known contact occurred at 02:33 a.m., the Brazilian air force spokesman added.
The assumption is that these electrical problems led to a catastrophic failure of the aircraft’s controls.
Some experts have said that a lightning strike was a possibility, particularly since the plane disappeared in a storm-prone area along the equator known as the Intertropical Convergence zone (ITCZ). This is where the trade winds of the Northern and Southern Hemispheres converge. The intense sun and warm water of the equator heats the air in the ITCZ, raising its humidity and making it buoyant. Aided by the convergence of the trade winds, the buoyant air rises, releasing the accumulated moisture in an almost constant series of thunderstorms.
According to CNN’s Mari Ramos, these storms can reach altitudes of 52,000 ft — way beyond the capacity of commercial airliners to fly over.
