"Black boxes" Russian aircraft A321, which crashed on October 31 in Sinai, recorded a distinct sound of an explosion, not associated with an engine malfunction. On Friday, November 6, with reference to "an investigator who had access to the" black box "of the Russian A321" reports the French edition of France 2. Flight information and sound recordings indicate that everything went on as usual until 24 minutes after takeoff when the flight recorders suddenly went out of order, indicating a "very sharp explosive decompression," a source told AFP. These data support the version of the explosive device on board the aircraft. Another interlocutor of the agency claims that the plane crash was sudden and very fast. Earlier, the Russian "Kommersant", citing sources close to the investigation, wrote that the decoding of the A321 parametric recorder, wrecked over Sinai on October 31, did not help establish the causes of the disaster.
Deciphering of the black box of the Russian A321 Kogalymavia plane, which crashed in Egypt on October 31, continues.
On this moment the experts have already completely decoded the data of the flight recorder in the cockpit.
Apparently, the crew of the A321 airliner, until the last moment, did not suspect about any malfunctions in the aircraft design, unless, of course, the crash happened because of this.
In addition, in the records of conversations with the dispatcher, there is not a single hint that the plane may need an emergency landing.
In general, everything indicates that the tragedy came as a surprise to absolutely everyone.
There is another interesting point in this tragedy - the length of the crash process. The fact is that the crash took place in several stages. According to the flight recorders, the A321 airliner flew at an altitude of about 9000 meters, but began to descend gradually, not abruptly. First, the plane descended 1000 meters. It happened in just a few seconds.
At this level, he held out for some time. Then there was another downward leap. In general, the crash took a long time, perhaps several minutes. However, during this time, the pilots no longer made contact with the ground. This indicates that the plane already had serious damage at that time - the news portal reports.
In turn, this confirms the version of the explosion of the plane. Almost all experts investigating the crash of the A321 in Egypt agree on this version. True, it is not yet clear why the plane exploded. The main version is a technical problem. The spark may have just entered the fuel tank.
It is also interesting that the examination established: the passengers of flight 9268 died in different time... That is, those passengers who were located in the back rows died first, and those who sat in the front rows died later. In addition, experts state that completely different injuries were found on two groups of passengers' bodies.
All this testifies to the fact that there really was an explosion in the plane, moreover, it happened in the back of the plane. Earlier, a video of the crash of the A321 airliner in Egypt appeared on the network.
The decoding of the Kogalymavia's Airbus А321 parametric recorder that crashed in the Sinai Peninsula did not help establish the cause of the largest plane crash in Russian history in terms of the number of victims.
The flight recorder data showed that during the flight, which lasted about 20 minutes, all aircraft systems were operating normally. According to the newspaper, the registration of the operating modes of all systems of the liner stopped with lightning speed, after the tail section, in which the recorder was located, was torn off the airbus.
The emergency situation on board developed so quickly that the crew of the aircraft, apparently, did not even have time to assess it and take any action. Sources of the publication suggest that the recordings of the speech recorder, which, moreover, was badly damaged, may also be useless.
Experts believe that this could have happened due to an explosive depressurization of the cabin, as a result of which its tail section, in which the emergency parametric recorder was located, was separated from the aircraft fuselage.
The publication reports that before the crash, the crew did not report emergency situation on board, as no problems were identified during the short flight. But in order to report an emergency, the pilots did not need to be in radio contact with the ground. It was enough just to press a certain combination of buttons, which would automatically transmit distress signals.
