Germanwings Flight 4U9525: Victims remembered at memorial service

The Germanwings crash last month was an "unbelievable horror" for the families of those killed, compounded by the apparent senselessness of the co-pilot's actions in bringing down the plane, German President Joachim Gauck told hundreds of victims' relatives and dignitaries at a memorial service today.

Gauck told the crowd gathered Friday that people across Germany, which lost 72 citizens, are still coming to grips with the March 24 crash. The second-biggest group of victims was from Spain, which lost 51 citizens.

Prosecutors have said co-pilot Andreas Lubitz deliberately crashed the plane into the French Alps on the flight from Barcelona to Duesseldorf, killing all 150 aboard. They are still trying to determine why.

"We really don't know what was going through his head during those deciding seconds, in the deciding minutes," Gauck said at the memorial, which was attended by German Chancellor Angela Merkel, ministers from Spain and France, and the heads of Germanwings and its parent airline, Lufthansa.

"But we do know that his relatives also lost on March 24 a person whom they loved, who leaves a void in their lives in a way for which they can find as little sense as all of the others' relatives," Gauck said. "Maybe that is what appalled us so much, the senselessness of what took place."

The steps to the altar were covered with 150 lighted candles, one for each person who died.

A choir sang hymns, and religious leaders said multi-denominational prayers.

Lufthansa carried a livestream on its website and took out full-page advertisements in many of the country's leading newspapers expressing sympathy. Flags were ordered flown at half-mastaround the country.

Cardinal Rainer Maria Woelki, the archbishop of Cologne, told victims' relatives that words alone were too weak to give them any solace, but that they should take comfort in the numbers of people at the memorial service, and those following it online or on television.

"You are not alone in these hours of loneliness," he said.
