Two Americans on Germanwings Plane, Official Says

Two Americans were on board the Germanwings flight that crashed in the French Alps Tuesday, according to Germanwings CEO Thomas Winkelmann.

Earlier, French Prime Minister Manuel Valls told reporters one American was on the plane. The U.S. State Department has not confirmed that any Americans were on board.

The Germanwings plane crashed Tuesday in the Alps in southern France with 150 people on board, including two babies, the airline said. French President Francois Hollande said there were "apparently no survivors."

Searchers returned to the crash scene today, as France's minister of the interior said a black box voice recorder from the plane is damaged. Even so, said the official, Bernard Cazeneuve, the information on the recorder should be retrievable.

The CEO of Lufthansa, which owns Germanwings, said a full analysis of the voice recorder was expected to be done by Thursday. But Brice Robin, public prosecutor of Marseille, said on BFM TV that black box results could take several days.
