Black Box Found At Germanwing Alps Crash Site

French authorities have called off the search for the remains of a Germanwings airplane that crashed into the French Alps with 150 people aboard, after night fell on the hard-to-reach area.

Lt. Col. Simon-Pierre Delannoy of the regional police rescue service said that the conditions for the search had become too difficult. Helicopters stopped flying over the area at nightfall.

The complex search operation was expected to resume Wednesday morning. The Airbus A320 was travelling from Barcelona to Dusseldorf when it crashed Tuesday on a mountainside near Meolans-Revels and the popular Pra Loup ski resort.

Earlier, French President François Hollande called the crash "a tragedy on our soil''.

There were no survivors from the crash of flight 4U9525, said Alain Vidalies, France's junior minister of transport.

French Interior Minister Bernard Cazeneuve has said that one of the plane's two black boxes was recovered from the crash site."
