June 1, 2009, SAO PAULO, Brazil – A missing Air France jet carrying 228 people from Rio de Janeiro to Paris ran into lightning and strong thunderstorms over the Atlantic Ocean, officials said today. Brazil began a search mission off its northeastern coast.

Chief Air France spokesman Francois Brousse said, "it is possible'' that the plane was hit by lightning.

Air France Flight 447, an Airbus A330, left Rio at 6 p.m. ET Sunday with 216 passengers and 12 crew members on board, company spokeswoman Brigitte Barrand.

About four hours later, the plane sent an automatic signal indicating electrical problems while going through strong turbulence, Air France said.


The plane `"crossed through a thunderous zone with strong turbulence'' at 10 p.m. ET Sunday. An automatic message was received fourteen minutes later `"signalling electrical circuit malfunction.''

Brazil's Air Force said the last contact it had with the jet was at 9:30 p.m. ET Sunday, but did not say where the plane was at that time.

Brazil's air force was searching near the archipelago of Fernando de Noronha, about 300 kilometres northeast of the coastal city of Natal, a spokesman said, speaking on condition of anonymity in keeping with department policy.

The region is about 2,400 kilometres northeast of Rio.

The head of investigation and accident prevention for Brazil's Civil Aeronautics Agency, Douglas Ferreira Machado, told Brazil's Globo TV that he believes the plane must have left Brazilian waters and could have been near the coast of Africa by the time contact was lost, based on the speed it was travelling.

"It's going to take a long time to carry out this search,'' he said. "It could be a long, sad story. The black box will be at the bottom of the sea.''

Air France-KLM CEO Pierre-Henri Gourgeon, at a news conference at Charles de Gaulle Airport north of Paris, said the pilot had 11,000 hours of flying experience, including 1,700 hours flying this aircraft. No name was released.

Aviation experts said the risk the plane was brought down by lightning was slim.

"Lightning issues have been considered since the beginning of aviation. They were far more prevalent when aircraft operated at low altitudes. They are less common now since it's easier to avoid thunderstorms,'' said Bill Voss, president and CEO of Flight Safety Foundation, Alexandria, Va.

He said planes have specific measures built in to help dissipate electricity along the aircraft's skin.

"I cannot recall in recent history any examples of aircraft being brought down by lightning,'' he told The Associated Press.

Experts said it was clear the plane was not in the air any longer, due to the amount of fuel it would have been carrying.

"The conclusion to be drawn is that something catastrophic happened on board that has caused this airplane to ditch in a controlled or an uncontrolled fashion,'' Jane's Aviation analyst Chris Yates told The Associated Press.

"I would suggest that potentially it went down very quickly and so quickly that the pilot on board didn't have a chance to make that emergency call,'' Yates said, adding that the possibilities ranged from mechanical failure to terrorism.

Families who arrived to meet passengers on board were cordoned off, away from reporters, at a special Air France information centre at the Charles de Gaulle airport. That centre said 60 French citizens were on the plane. Italy said at least three passengers were Italian.

"Air France shares the emotion and worry of the families concerned,'' Barrand said.

The flight was supposed to arrive in Paris at 5:15 a.m. ET, according to the airport.

Airbus said it was co-operating with transport authorities and Air France, but would not further comment until more details emerged.

"Our thoughts are with the passengers and with the families of the passengers,'' said Airbus spokeswoman Maggie Bergsma.

French President Nicolas Sarkozy expressed his "extreme worry'' and planned to visit the Charles de Gaulle airport later Monday.
