Update:
A spokesman for France's DGAC aviation authority said the airliner crashed near the town of Barcelonnette about 100 km (65 miles) north of the French Riviera city of Nice, and not far from the Northwest border of Italy.
This region is about 2,300 meters above sea level and is full of snow.
400 rescue workers are already in the area, which is hard to reach.
2,000 French Gendarme have also been mobilized to help search the area.
Massive snow is predicted for this area today.
No one knows why the plane crashed, but the radar shows that it suddenly dropped like lead.
No difficulties were reported within Spanish airspace.
The plane was supposed to land at noon in Düsseldorf, Germany.
Extra clergy has been brought to the airport in Düsseldorf and brought those who were waiting on the flight to arrive into an area to inform them and counsel them.
43 passengers were Spanish citizens. A great number, perhaps the majority, were German citizens, on their way back from Spain.
Düsseldorf is one of the finer international airports out there, I've flown in and out of Düsseldorf a number of times. Sad day in Germany.
