Air accident
investigators extract audio from cockpit voice recorder and ‘remain optimistic’
about finding second black box of flight 4U9525.
French air accident investigators say they have extracted a
recording that contains “voices and sounds” from the cockpit of Germanwings
flight 4U9525that
crashed on Tuesday, killing all 150 on board.
The Airbus A320 that ploughed into an
Alpine mountain flew “right to the end”, the investigators said, and did not
explode mid-flight. It also appeared not to have suffered a sudden drop in
pressure.
The audio file was extracted from the
cockpit voice recorder, one of the black boxes discovered in the wreckage of
the plane, which was en route from Barcelona to Düsseldorf.
The French Bureau d’Enquêtes et d’Analyses (BEA) said it was
“optimistic” the second black box, the flight data recorder, would be found and
the mystery of the crash solved.
“We have an audio file we can use,” Rémi
Jouty, a BEA spokesperson said.
The task of the investigators in the
first instance is “a job … of understanding the sounds, the alarms, the voices,
to attribute the voices to different people,” he added.
“The crash zone is two hectares, which
is big but not massive. We are combing the site and we will find the flight
data recorder, which is built to resist a severe crash. I am confident we will
find out what happened.”
Carsten
Spohr, CEO of Lufthansa, the parent airline of Germanwings, said it was doing
what it could to help the families of the victims, including offering flights
to the crash site.

“Running
an airline during such an accident is terrible,” he said at a press conference
in Barcelona, adding that the Airbus 320 had been given a clean maintenance
bill on Monday.
On
Wednesday, grieving families of the 150 victims – mostly Spanish and German – began to arrive in Alpine
villages around the crash zone.
Germanwings
chief executive, Thomas Winkelmann, said that 72 Germans had died. In a statement
on Wednesday afternoon, Spain’s government said 51 of the dead were Spanish.
At least three Britons are
believed to be among the dead, as well as two Americans.
Casualties have been confirmed from at least 16 countries overall.
Aviation experts have been
puzzled as to why the plane failed to respond to calls from air traffic control and why the pilots did not send out a distress
signal as the plane dropped steadily for more than eight minutes before
ploughing into a mountain ravine.
Jouty
said it was too early to give details of the cockpit recording. However, he
said the information investigators had put together suggested the plane had not
exploded and did not suffer a “classic decompression situation”.
Investigators refused to say more about what the cockpit
recording contained.
“We have had this for a few minutes and
we cannot say who is speaking. It takes time to understand these things. It’s
too soon to draw conclusions about what happened,”Jouty said.
Investigators say the last recorded
message from the plane came at 10.30am local time, when air traffic control at
Aix-en-Provence responded to the crew’s request for permission to continue its
route.
“A little while afterwards, the aircraft
started a descent that it continued right up to impact just under ten minutes
later,” Jouty said.
“We lost a radar signal from the
aircraft extremely close to the site of impact. At which point the aircraft was
at 6000 ft. The radar followed the plane to just before impact.”
He added investigators needed to explain
why the plane continued to descend and did not respond to calls from air
traffic control.
“We had some difficult to read it, but
to our relief we have succeeded in extracting an information file, an audio
file, that we can use. Now we have to work on the audio file to understand the
sounds and voices that can be heard.”
Asked about the aircraft’s apparently
controlled descent before it crashed, he added: “The path is compatible with
the plane being controlled by pilots, except it’s hard to imagine that a pilot
would send an aircraft into a mountain, and it’s compatible with an autopilot.”
He was unwilling to give any more
information.
Air traffic controllers reported total
radio silence from the plane as it descended before smashing into the mountain.
After postponing the search on Tuesday
evening, hundreds of gendarmes, firefighters and mountain rescue teams returned
at dawn on Wednesday to comb the rocky ravine in the southern Alps, between the
villages of Digne-Les-Bains and Barcelonnette, where debris from flight 4U9525
is scattered.
Some had to walk three hours to reach
the crash spot. Others had to be winched down from helicopters hovering over
ravine that struggled to maintain their position in the wind. Rescue teams
spoke of the impossibility of landing anywhere near the base of the steep
escarpment.
An air investigation team from Paris has
also arrived at the scene and was joined by three German colleagues.
In Seyne-les-Alpes, the picturesque
alpine mountain village of 1,500 people which has been transformed into a
makeshift centre of operations, support staff received the first relatives of
the victims. Many families had chosen to fly to Marseille overnight and be
taken by bus to the Alps to get as near as possible to the crash site and to
begin grieving as they waited for relatives’ remains.
In the village, there was a mood of
grief and sadness. Looking up at the mountain beyond which the plane had
crashed, Maurice Borel, a retired volunteer firefighter, said: “We’re in shock,
nothing of this scale has ever happened here before.”
The Seyne-les-Alpes youth centre, which
would normally be packed with riotous children’s sports clubs on a Wednesday
afternoon, had been made into a silent makeshift chapel and remembrance centre
for the victims’ relatives.
“We just feel so powerless,” said René
Dufour, a retired textile worker, as he looked out towards the snowy peaks
beyond which the plane crashed. “All we can do is send all our thoughts to the
families.”
The French president, François Hollande, visited the area on
Wednesday afternoon with the German chancellor, Angela Merkel, and Spanish
prime minister, Mariano Rajoy. At a joint press conference they pledged to do
everything they could to find the cause of the crash.
The Airbus appears to have smashed into
the mountain at a speed of around 700km/h (more than 430mph) violently
shattering the plane into small pieces. Among the debris, investigators have
the grim task of finding the remains of the 144 passengers, including two
babies and 16 schoolchildren, as well as six crew.
On Wednesday, staff at Germanwings’
headquarters in Cologne held a silent tribute to the dead.
Teachers and pupils from the
Joseph-König high school in the western German town of Haltern held a special
assembly in memory of 16 pupils and two teachers who died in the crash while
returning from an exchange trip.
Brice Robin, prosecutor for the city of
Marseille, said the investigation would take weeks.
“The priority on the ground is to
identify the bodies,” he told reporters after flying over the crash site.
“We owe that to the families of the
victims. But it will not be done in five minutes. It is going to take a number
of weeks and I think everyone should be aware that we are talking about a long
time.”
Asked about the causes of the crash he
said “at the moment the reasons are completely undecided”.
Earlier he told Reuters what he saw over
the crash site: “We saw an aircraft that had literally been ripped apart, the
bodies are in a state of destruction, there is not one intact piece of wing or
fuselage.”
