Details of the Germanwings crash from Tuesday
Recovery crews had suspended their operations late Tuesday as nightfall made conditions too difficult to continue the search.
Rescue teams were due to focus on locating and recovering the second black box, which records flight data, as well as recovering remains and investigating what caused the crash.
The pilots did not sent out a distress call as the plane descended over a time of eight minutes, shortly after reaching cruising altitude on the flight from Barcelona to Düsseldorf. It crashed shortly after 11 a.m. local time Tuesday in a rugged area of the southern French Alps near the town of Seyne-Les-Alpes.
"The site is a picture of horror. The grief of the families and friends is immeasurable," German Foreign Minister Frank-Walter Steinmeier said Tuesday after being flown over the crash scene. "We must now stand together. We are united in our great grief."
German Chancellor Angela Merkel is due to travel to the site Wednesday to pay her respects and bear witness to the recovery efforts, alongside Spanish Prime Minister Mariano Rajoy and French President Francois Hollande.
Merkel will also be accompanied by Hannelore Kraft, the premier of the German state of North Rhine-Westphalia (NRW), of which the plane's destination Düsseldorf is the capital. The town of Haltern am See, which had 16 high school students and two teachers amongst the crash victims, is also in NRW.
The crash involving one of Germany's biggest airlines, which had a good safety record, has shocked Europe.
