0October 31, 2015 At 6 am, at Sharm El Sheikh International Airport in Egypt, an Airbus A321-231 passenger plane (registered number EI-ETJ, 18 years old at the time of the incident, belonging to an old aircraft, which had previously been affiliated with several airlines) is preparing for takeoff. The aircraft will be flying a tourist charter flight codenamed 7K9268 from the Egyptian-level Sharm El Sheikh International Airport to the Pulkovo International Airport in St. Petersburg, Russia (Sharm El Sheikh is a famous Red Sea coast tourist city and is the first choice for many people in Eastern European countries such as Russia, , Ukraine, and ). There were 2 crew members, 5 crew members and 217 passengers on board at that time. Except for 3 Ukrainian tourists and 1 Belarusian tourist, the remaining 213 tourists were Russians (including 25 children, the youngest was only 10 months old).

5:51, Kogarem Airlines Flight 7K9268 successfully took off from the 4R runway of Sharm El Sheikh International Airport and flew north. If all goes well, flight 7K9268 will arrive in St. Petersburg in 4 hours and 40 minutes.
Sharm El Sheikh Tower: "Kogarem 9268, please contact Nikosia after leaving the field."
Captain: "Kogarem 9268 received, Sharm El Sheikh. You will be notified after leaving Egyptian airspace."
After 20 minutes of flight, flight 7K9268, which is still climbing, is preparing to leave Egyptian airspace. Egyptian air controllers are also preparing to hand over the guidance of the passenger plane to the Cyprus Air Control Center.
Co-pilot: "I'll check the queuing for the next few days."
At this time, the flight attendant held the tray of Sheng Guyou's two cups of black tea and rang the cockpit doorbell. The captain took a look in the surveillance camera and opened the cockpit door. Captain
: "Please come in."
flight attendant: "Black tea for both gentlemen."
: "Thank you very much."
co-pilot: "You are so good."
flight attendant: "Oh, since you said that, you won't charge for your tea."
: "Hahaha."
: At 6:12, flight 7K9268 climbed to a cruising altitude of 31,000 feet (9,448 meters). Everything seemed very normal, but in just one minute, the tragedy was about to begin.
6:13, nearly 23 minutes after flight 7K9268 took off at Sharm El Sheikh Airport, the flight suddenly showed a sharp drop from 31,000 feet on the Sharm El Sheikh Tower Control Radar screen, and the aircraft altitude dropped by 5,000 feet in just 21 seconds, and disappeared from the radar display soon after.
Sharm El Sheikh Tower: "Kogarem 9268, are you encountering any problems?"
is busy.
Sharm El Sheikh Tower: "Kogarem 9268, please answer when you hear it."
is still a busy voice. Something must have happened to

Kogarem 7K9268 flight wreckage
After receiving the news that Kogarem 7K9268 flight was lost, the Egyptian-class air force quickly sent a helicopter to the place where the passenger plane was lost, the desert area of the central Sinai Peninsula. Finally, with the help of local tribal armed forces, the wreckage of the EI-ETJ A321-231 passenger plane of Kogarem 7K9268, which had fallen into a pile of debris, was found in a desert. The wreckage was scattered on a narrow strip of about 13 kilometers. The tail part was the farthest away from the fuselage but the structure was relatively recognizable, while the fuselage had disintegrated and was difficult to identify. However, since the crash site was located in a war zone where the Egyptian government forces and the extremist organization ISIS had exchanged fierce fire and repeated tug-of-war, rescuers on the ground did not enter the crash site until around 18:00 that day with a rescue convoy of 45 vehicles, protected by military vehicles. There was no sign of survival of any personnel at the scene, and all 224 people on board were killed, none of them survived. This air crash became the most serious air crash in Russia's civil aviation history, shocking Russia.
Kogarem 9268 flight crash site, you can vaguely see the traces of the nose and wings, but the tail part of the plane is no longer known to go to
air crash news returned to Russia. On the day of the accident, Russian President Putin signed a decree to declare November 1 as Russia's national mourning day. All Russia's territory was lowered from half of the flag and various TV stations stopped broadcasting entertainment programs to mourn the victims of the Russian passenger plane crash on October 31. On November 1, 2015, local time, Russia lowered half of the flag to mourn the victims of the crashed passenger plane in Egypt. St. Petersburg City Government announced that the city's mourning activities will last for three days. The St. Petersburg Municipal Government lowered the Russian flag and the city flag at half a flag to mourn the victims.
After the Russian officials confirmed that all the people on board were killed on the same day, people began to go to St. Petersburg to mourn Pulkovo Airport . They presented flowers, lit candles, and sent dolls to the children who died. The airport has also opened a special area for people to go to mourn.

then Russian Prime Minister Medvedev At Putin's instruction, a special national committee was established to deal with the investigation and aftermath of the Sinai air crash. Three planes (two Il-76s and one Be-200), a rescue team and an investigation team were sent to Egypt to be responsible for the wreckage of the Kogarem 7K9268 passenger plane, the remains of the victims, and the investigation into the cause of the crash. As of November 1, 2015, 175 bodies of the deceased have been found at the scene. On the same day, St. Petersburg, Russia has begun to collect DNA samples from families of the Egyptian air crash victims.
Air crash investigation team consists of multiple parties: the French Aviation Accident Investigation Agency (BEA) dispatches two safety investigators, six technical consultants from Airbus, two investigators from the German Federal Aviation Accident Investigation Agency, and four investigators from the Russian Interstate Aviation Commission (MAK).

Accident investigation team analyzed the initial flight trajectory and found that 23 minutes after the plane took off, when it reached an altitude of 31,000 feet and entered the stratosphere cruise flight, an abnormal situation occurred. The aircraft suddenly fell at an average speed of about 1,100 meters per minute. When viewing the detailed data, it was found that the maximum speed of the fall had reached 2,438 meters per minute. The horizontal flight speed also dropped from 406 knots (751 km/h) during stratosphere cruise flight to 62 knots (115 km/h) in just 24 seconds. This speed is already lower than the stall protection speed of the A321 flight control system. It can be considered that the aircraft is in a stall state at this moment, and the stall protection cannot take effect.
, and the flight data of flight 7K9268 in the last half minute was restored by reading the data in the flight data logger:
4:12:52, the aircraft completed the climb at a rate of 512 feet per minute and started the cruise at an altitude of 30,875 feet.
4:12:58, the plane suddenly climbed, and the instantaneous climb rate was 3584 feet per minute.
4 at 13:00, the plane fell, with a descent rate of 8,000 feet per minute and a speed of 406 knots.
4:13:3 seconds, the plane climbed, with a climb rate of 5696 feet per minute.
4 at 13:00 pm, the plane fell and the descent rate was 4544 feet per minute.
4:13:11, the plane climbed, with a climb rate of 6080 feet per minute.
4 at 13:19, the plane fell and the descent rate was 7808 feet per minute.
4 at 13:22, the plane fell, with a descent rate of 6528 feet per minute and a final speed of 62 knots.

From the data, it can be seen from the data that the aircraft was in an extremely unstable state at the last time before the crash, like a roller coaster, in a huge overload, very much like a sign of the plane's horizontal tail wing losing control. And its too low speed inevitably stalls the aircraft, which eventually leads to a crash. What is certain is that the plane had disintegrated in the air before the crash, and the wreckage had obvious signs of overfire, and the fire source obviously came from the 23 tons of aviation fuel added before takeoff.
First of all, the investigation team suspected that the short circuit of the wire caused the explosion to cause the plane to disintegrate in the air, similar to the Long Island crash of Global Airlines Flight 800 (for details, please see our factory manager
armed personnel carrying SA18 air defense missiles on their shoulders
Both Russia and Egypt denied it. The BBC quoted the opinions of the investigation team experts, pointing out that although there are indeed a large number of shoulder-mounted surface-to-air missiles in the Sinai province of Egypt controlled by ISIS, the flight altitude of the Kogarem 7K9268 flight is 31,000 GB The squad is about 9450 meters, which is far beyond the range of any shoulder-mounted surface-to-air missile (the SA18 air defense missile can only hit 11,000 feet at most).
The subsequent investigation focused on Sergey Trukachev, the co-pilot of Kogarem 7K9268 flight. He revealed in the phone call to his wife and daughter before takeoff that the EI-ETJ A321-231 passenger plane was not in good condition, after all, it was an old aircraft with an age of more than 18 years. "In his call with his daughter before takeoff, he said that the technical status of the aircraft could not meet the takeoff."

Investigation team then visited the technician who last maintained the EI-ETJ before taking off. The technician insisted that although they only had half an hour of maintenance, the aircraft was in good condition and there was no major problem. However, the maintenance records show that the plane was too high when it landed at Cairo Airport in 14 years ago, that is, in 2001, the angle was too large, which caused the tail to rub. The ground was damaged to a certain extent, but it has undergone a thorough repair that meets the requirements of Airbus specifications, and should not be the cause of this crash (similar reason caused the disintegration of China Airlines flight 611 in the air over Penghu.

After re-examining the wreckage at the rear of the aircraft, the investigation team found the explosion site and the small amount of explosives remaining on the wreckage at the explosion site, confirming that it was because an explosive was exploded on the passenger plane, which eventually caused the plane to disintegrate in the air and then crashed. It was who brought the explosives on the plane, suspected that the target was transferred again to the head of the Islamic State, an extremist organization claimed to be responsible for the crash of Kogarem 7K9268 flight.
20151 On January 17, the Russian government said that the Russian passenger plane crashed in Egypt encountered a "terrorist attack" and the explosives were equivalent to 1 kilogram of TNT explosives; and offered a reward of $50 million to buy the heads of the relevant personnel planning the terrorist attack.
can bomb made by the Islamic State organization
investigation team first checked everyone who boarded the Kogarem 7K9268 flight that day The officers ruled out the possibility of their crimes one by one, and then shifted the investigation target to the heads of workers responsible for carrying baggage at Sharm El Sheikh Airport. The result of the investigation was: a luggage porter's uncle is a member of the Islamic State. He bribed the security police at Sharm El Sheikh Airport and placed several small bombs disguised as cans of soda drinks into the luggage compartment of Kogarem 7K9268. The bomb set the explosion altitude just as the aircraft's cruise altitude explosion, and the explosion caused the rear structure of the aircraft. The cabin lost pressure, and the rear part of the rear of the 25th row seat position was then removed from the fuselage. The flight attendant who was distributing drinks and snacks to passengers and some passengers who were not wearing seat belts (at the cruise altitude, passengers can release the seat belt and get up and walk around) were first sucked out of the plane, and the plane lost control completely and eventually crashed.
