Germanwings plane black box found as mystery surrounds Alps crash

42French air investigators are urgently examining a black box cockpit voice recorder (CVR)from a Germanwings Airbus A-320 to try to solve the mystery of why the aircraft crashed into a mountain in the southern Alps, killing all 150 people on board.Investigators are puzzled as to why the crew did not send out a mayday or distress signal as flight U49525 rapidly lost altitude for eight minutes, or why the pilot did not change course to avoid smashing into a rocky ravine at around 430mph (700kmh). In the last 10 minutes of the flight there was total radio silence from the crew of the Barcelona–Düsseldorf flight operated by Lufthansa’s low-cost subsidiary.Tuesday’s crash happened around 11am local time in calm weather. Unverified information from plane-tracking websites appeared to rule out an explosion or a mid-air stall, both of which would cause a much faster descent. Experts said planes such as the Airbus would be able to glide for some distance in the case of total engine failure.David Learmount, the operations and safety editor of Flightglobal, said on Twitter:  “German-operated A320s do not crash in the cruise. Not these days. This one is weird.”The French prime minister, Manuel Valls, said a helicopter crew had landed near the crash site and found no survivors. Aerial photos showed the plane was, in the words of one official, “pulverised”. The lar44gest piece of wreckage was little more than the size of a small car.As the CVR was being analysed,Pierre-Henri Brandet, a spokesman for the French interior ministry in Seyne-les-Alpes, said the search for bodies and a second black box on the isolated, rocky site had been called off for the evening and would resume at dawn. Among the dead passengers were two babies, and 16 German school pupils returning from an exchange trip toSpain with their two teachers.Christophe Castaner, a Socialist party MP, was one of the first to fly over the barren high altitude crash site and described a scene of horror.“It’s a sharp ridge and steep slope that is difficult to access. We have seen the catastrophe and terrible things. It was clear the victims were there in the midst of the destroyed aircraft.“We saw women, men, children, and babies. Yes, we saw babies,” the visibly shocked Castaner told journalists.Jean-Louis Bietrix, a mountain guide who accompanied the first emergency services up the mountain, said there was nothing left of the plane.“There’s debris, but you have to look closely to see things. It’s like the plane has totally disappeared,” he said.The German foreign minister, Frank-Walter Stein46meier, said the crash site was “a picture of horror. The grief of the families and friends is immeasurable. We must now stand together. We are united in our great grief.”The crash site can only be accessed after a three-hour walk from the nearest road.It is the worst air accident in France since 345 people were killed when a Turkish Airlines DC10 crashed near Paris in 1974. In 2000 an Air France Concorde crashed shortly after takeoff from Charles de Gaulle airport in Paris in July 2000, killing all 100 German passengers, nine crew and four people on the ground.Valls said “no hypothesis” could be ruled out about the cause of the tragedy.Bernard Cazeneuve, the interior minister, said the black box had been sent to the Bureau d’Enquêtes et d’Analyses (BEA), the French air accident investigation authority, for “immediate examination”.He added that the crash zone had been secured and that a criminal investigation team would arrive to collect evidence on Wednesday.The dead, including two pilots and four cabin crew, are believed to include 45 Spanish and 67 German nationals. The French president, François Hollande, also spoke of a Turkish national among the victims. A helicopter flies over the crash scene where debris from the Germanwings A320 plane can be seen.

It was just under halfway through its journey to Düsseldorf, where it had been expected to land at 11.55am, when it began to lose altitude.The French aviation regulatory authority (DGAC) said the aircraft did not issue a distress call, as initially reported, but that its sudden drop in altitude had led air traffic controllers to implement the “distress phase”. This is the third and most serious of three alerts used to help identify and coordinate rescue efforts when a plane is thought to be in difficulty.The chief executive of Germanwings, Thomas Winkelmann, told a press conference: “At 10.35am the plane had reached 38,000 feet, but after 10 minutes it was in downfall and was losing altitude
That lasted eight minutes. The contact with the aircraft with French radar was lost at 10.53am at which point the plane was around 6,000ft. The plane then crashed.” Thomas Winkelmann, Germanwings chief executive, on the plane’s final descentAfterwards, there was conflicting information over the timings. The flight tracking website FlightRadar24 claimed the plane started dropping at 10.31am, fell 31,000ft in nine minutes and vanished off the radar at 10.40am.Aviation experts questioned Winkelmann’s suggestion the plane had stalled, saying that, while its descent was rapid, the crew appeared to have some control until shortly before the crash.Rescue helicopters located the wreckage soon afterwards in the grey, stony cleft of a mountain range high in the southern French Alps, between Digne-les-Bains and Barcelonnette. Hundreds of gendarmes, firefighters and emergency search and rescue teams, as well as 10 helicopters and a military aircraft, were dispatched to the crash site to search for survivors.The crash zone is isolated, extremely difficult to reach and completely inaccessible to vehicles. Rescuers were unsure if they would arrive before nightfall, when weather conditions were expected to deteriorate.Local councillor Gilbert Sauvan, who flew over the crash site, said there was “very little left of the aircraft”.“The biggest pieces must be the size of a car, no bigger,” Sauvan said. “I would say there was no chance of finding anyone who survived.”Florent Plazy, director of the local ski school ESF, confirmed the area was hard to access, even for mountain walkers, and said the rescue operation would be “extremely complicated”. Pierre Polizzi, the owner of a campsite near where the plane crashed, said he heard the plane making strange noises shortly before it disappeared. “I heard a series of loud noises in the air. There are often fighter jets flying over, so I thought it sounded just like that. I looked outside, but I couldn’t see any fighter planes,” Polizzi told the Associated Press. “The noise I heard was long, like eight seconds, as if the plane was going more slowly than military plane speed. There was another long noise after about 30 seconds.” Polizzi said the plane crashed around 3-11 miles (5-8km) north of his camp. “It’s going to be very difficult to get there. The mountain is snowy and very hostile.”The French government set up an emergency centre and sent the interior minister, Bernard Cazeneuve, to the scene. President François Hollande said: “The causes of the accident are not yet known but suggest no survivors. I would like to send all our solidarity to the family of the victims.”He said he was in regular communication with Merkel and King Felipe VI of Spain, who was visiting the Elysée Palace in Paris at the time of the crash, but cut short his state visit after the news broke.“It’s a new air tragedy; we must know all the causes. We are in mourning because this accident happened on our territory,” Holland said.The Airbus A-320-211 named “Mannheim” with the registration D-AIPX, was at the end of its commercial flying life, according to La Provence newspaper. Its first flight was on 29 November 1990 and it had been flown commercially by Lufthansa/Germanwings since 1991.The Germanwings chief said: “The last checkup for the plane was in March at Düsseldorf by our technical teams. The last major checkup laid down by Airbus procedure was in summer 2013.” He said the captain of the plane had more than 10 years’ experience with Lufthansa and Germanwings, and 6,000 hours of flight on the Airbus. A visualisation, created by CartoDB founder Sergio Álvarez, shows the path of the plane, and its speed.A spokesperson for the British prime minister, David Cameron, said: “He has been informed of this tragic news of the aircraft that has been lost over southern France and he would wish to express how his thoughts are very much with the families and friends of all of those who were on that flight.“If there is any assistance or role that UK air accident investigators can play in response to this then of course the French and German forces will have our full support and engagement on that.”
