In aviation, unfortunately, not everything depends on the experience of the crew and the serviceability of the liner. Very often the so-called "human factor" acts as the arbiter of destinies. But often, when it is not possible to determine the real cause of a plane crash, everything is simply attributed to this “human factor”.
Investigations of plane crashes in the pre-reform era were a state secret that was strictly guarded. For the public, their results remained a secret with seven seals. Today the situation has changed quite significantly. The Society of Aviation Accidents Investigators (ORAP) has been established in Russia. Every year, its members hold conferences at which the smallest detail of tragic events is openly discussed, every, even insignificant manipulation of pilots, the work of all aircraft systems is analyzed seconds before the fatal meeting with the ground.
But has there been less disasters from this? Has it become easier to investigate the disasters themselves?
Despite the most sophisticated methods of researchers and the accumulated experience, there are no less mysteries and mysteries that have not been answered, despite all efforts. There are many examples of this.
For example, the version of the death of the Yak-40 aircraft in 1997 in Azerbaijan is the destruction of oxygen cylinders with firearms. They even managed to detain a soldier who was firing a machine gun at this time and in this place.
As it was established by an official investigation, round holes with a diameter of 8 mm were found in both aircraft cylinders. In addition, with the help of an examination, copper plating was found in the cylinders and on the holes themselves, which confirms the bullet defeat due to the fact that the bullet just has a copper sheath. The forensic examination also confirmed the "bullet" version. At first glance, the conclusion is obvious - the culprit of the disaster and death of people is a soldier who fired in the wrong place and hit the oxygen tanks of the aircraft. But when examining the hole on an electron microscope, it turned out that the "bullet" not only entered, but also exited through it, which in itself is unlikely. In addition, they did not find the outlet, allegedly for the reason that during the fall, the tank was destroyed on the side where the outlet should have been. The bullet itself was also not found.
This secret has not yet been solved, but one thing is for sure - the soldier is not to blame. And this is far from the only case.
So, in the same 1997, the American Boeing-747 was supposed to fly from Odessa to the Greek Thessaloniki, but it was found to be malfunctioning. Therefore, the Yak-42 was called from Lvov. It was he who set off at night along the route that became the last for him and the passengers. It was led by the most experienced pilot Starodubtsev, besides there was a very experienced pilot-instructor on board.

We flew safely to Thessaloniki. It was found that the plane crossed the landing strip at an altitude of 250 meters. And then something completely incomprehensible happened - the plane suddenly began to move away from the airport. The crew was instructed to turn right at the airport radio beacon, gaining an altitude of 1800 meters. The crew responded to inquiries from the ground that the aircraft was performing a maneuver and was located where the dispatchers had instructed it to make a go-around approach. However, in reality this was absolutely not the case - in fact, he flew away from the airfield, towards his death. The tragedy took place 70 kilometers above the mountains. All crew members and passengers were killed. Not only Russians, but also specialists from Greece and Ukraine took part in the investigation of this plane crash. "Black boxes" were deciphered both in Russia and in Germany. But,despite this, it has not yet been possible to give a clear answer to the question of why the aircraft made this maneuver.
The mystery of the Irkutsk tragedy has not yet been solved either. An-124 military transport aircraft on December 6, 1997, while taking off, crashed into a residential area. Within a few seconds after the plane left the runway, the third and first engines were turned off, after which the second engine also failed. The crew made an attempt to keep the plane on one remaining engine, but it was unsuccessful. The disaster claimed the lives of 72 people - fifteen crew members, eight passengers and dozens of people from two destroyed houses. This terrible tragedy contains unsolved mysteries, complex and contradictory mysteries. Attempts to find out the cause of engine failure were unsuccessful. Both flight recorders were badly damaged. The reasons for turning them off as an experiment,and with the help of means of objective control it was not possible to finally establish.
Why do motors fail? The reason for the failure of aircraft technology is very often called phenomena unexplained to science, anomalous phenomena. Strange natural phenomena often provoke plane crashes, and sometimes planes even disappear without a trace. It is impossible to say unequivocally - there is some truth in such assumptions or it is all not true. Of course, most accidents occur precisely because of design flaws, unreliable security systems and other nuances that at first seem not so important, but ultimately cost the lives of hundreds of people. However, one cannot exclude a certain mysticism and a supernatural factor, on which many continue to insist. We cannot yet prove or disprove the involvement of these or those supernatural forces in the death of aircraft. If such reasons as weather conditions, military action,errors of pilots or dispatchers are quite understandable and understandable, then an unexpected failure of the on-board computer is perhaps the most terrible. According to skeptics, all phenomena can be found scientifically. Only, apparently, scientists are not yet able to do this.
