An Air France plane missing over the Atlantic with 228 people aboard reported electrical problems in stormy weather before it lost contact, the airline said Monday, describing the loss as a catastrophe. The Airbus A330-200 sent automatic messages signaling equipment failure as it hit turbulence early in its 11-hour flight from Rio de Janeiro to Charles de Gaulle airport in Paris, Air France CEO Pierre-Henri Gourgeon told a news conference. The last known contact with the plane was at 1:33 a.m. GMT (8:33 p.m. Sunday night ET), according to the Brazilian Air Force.  Brazil says it has launched two air force squadrons to hunt near the archipelago of Fernando de Noronha in the Atlantic Ocean, 365 kilometers (226 miles) from its coast, although the plane vanished outside the country’s radar coverage.
