RIO DE JANEIRO - An Air France jet with 228 people on a flight to Paris vanished over the Atlantic Ocean after flying into towering thunderstorms and sending an automated message that the electrical system had failed. A vast search began Monday, but all aboard were feared killed.
Military aircraft scrambled out to the center of the Atlantic, far from the coasts of Brazil and West Africa, and France sought U.S. satellite help to find the wreckage. The first military ship wasn't expected to reach the area where the plane disappeared until Wednesday.
If there are no survivors, it would be the world's worst aviation disaster since 2001.
The official Agencia Brasil news agency on Monday quoted Brazilian Air Force spokesman Col. Jorge Amaral as saying that a commercial airplane pilot saw what appeared to be fire on the ocean near the route taken by the Air France plane.
"There is information that the pilot of a TAM aircraft saw several orange points on the ocean while flying over the region ... where the Air France plane disappeared," Amaral said, referring to the Brazilian airline TAM. "After arriving in Brazil, the pilot found out about the disappearance (of the Air France plane) and said that he thought those points on the ocean were fire."
French President Nicolas Sarkozy said the cause remains unclear and that "no hypothesis" is being excluded. Some experts dismissed speculation that lightning might have brought the plane down. But violent thunderheads reaching more than 50,000 feet high can pound planes with hail and high winds, causing structural damage if pilots can't maneuver around them.
Sarkozy said he told family members of passengers on Air France Flight 447 that prospects of finding survivors are "very small."
