Where the Germanwings Plane Crashed

A passenger plane carrying 150 people from Barcelona to Düsseldorf, Germany, crashed in the French Alps on Tuesday. The French authorities said no one survived.The plane went down in a remote part of the Alpes-de-Haute-Provence department, and search teams struggled to get to the area. When French air traffic controllers lost contact with the aircraft, it was flying at approximately 6,000 feet; the elevations in the search area range between 2,000 and 9,000 feet.

No helicopters have been able to land because of the rugged terrain around the crash site. Searchers had to be lowered, further slowing recovery efforts. The size of the debris area, which was about the size of three to four football fields, suggests the plane hit the ground at a very high speed, according to the French interior minister, Bernard Cazeneuve.

The jetliner reached a cruising altitude of 38,000 feet but remained there for only a few minutes before beginning to descend rapidly.

A senior military official involved in the investigation said evidence from a cockpit voice recorder indicated one pilot left the cockpit before the plane’s descent and was unable to get back in.
1Before the descent, the pilot who was locked out of the cockpit “is knocking lightly on the door and there is no answer,” the investigator said. He then tried to smash the door in.

2The plane descended steadily at about 3,400 feet per minute, roughly twice as fast as a typical descent but within the capability of the aircraft.

3It is unclear why the plane continued to descend on a day with high visibility. One possibility is that the pilot in the cockpit, who did not communicate with air traffic controllers during the descent, was incapacitated.
