The Air France jet which went missing over the Atlantic sent 24 error messages before it is believed to have crashed, French investigators say.
The messages came as the plane's systems broke down one by one, said Alain Bouillard, head of France's aviation accident investigation bureau.
French weather experts said there was no evidence the plane, carrying 228 people, hit an "exceptional" storm.
The Airbus A330 vanished en-route from Rio de Janeiro to Paris on Monday.
