(PRAVDA) — Russia’s Ministry for Transportation does not consider a terrorist attack to be one of the versions that led to the crash of the Tu-154 passenger airliner of the Russian Defence Ministry in the Black Sea on December 25. For the time being, we know that the weather was fine, the pilots were experienced, and the aircraft was technically sound.
The crash of the Tu-154 over the Black Sea looks very much like the explosion of the Russian passenger jetliner over Sinai Peninsula, when the Federal Security Bureau made an official announcement about the terrorist attack only two weeks after the crash. There is another version – of radio-electronic attack.
Black boxes may not give an answer to the question of whether there was a terrorist attack on board the Tu-154. This has already been the case in the investigation of the Sinai plane crash, before specialists found traces of two-component explosives in a can of Coke, hidden in a seat pocket. The explosion caused the plane to collapse in midair. This explained the reason why the fragments of the aircraft were scattered on a large territory, FSB Director Bortnikov then said.
The Tu-154B MO, Flight RA-85572, took off from Chkalovsky military airfield near Moscow on December 25th. The aircraft was en route to Damascus with a refuelling stop in Mozdok on a regular route across the Caspian Sea, Iran, Iraq and the whole of Syria. Mozdok was closed, and the plane detoured for 408 km in the opposite direction, to Adler, even though there were other airports working nearby (Mineralniye Vody, Nalchik, Makhachkala). Allegedly, the passengers of the aircraft were not allowed to leave the airplane in Adler for two hours. Reportedly, no one boarded the plane and nothing was loaded on the aircraft either. The plane was only refuelled, and then it took off at 5.25 a.m. Two minutes later, at 5.27 a.m., Flight RA-85572 stopped responding to dispatchers and went off radar screens.
During one of the briefings of the Ministry of Defence, the map showed that the plane disappeared from radar screens immediately after making a turn of 180 degrees. However, flightradar24 real time tracker did not reflect such a manoeuvre. Was the transponder turned off?
After the crash, the wreckage was scattered over an area of ​​about 10-12 square kilometers. Was it a current or an explosion? The Ministry for Transport said that the version of the terrorist act was not among the priorities. FSB officials rejected the version too.
Versions of the disaster
The basic versions of the crash are the following: a piloting error, a technical malfunction and improper alignment of cargo on board the plane. However, Tu-154 commander Roman Volkov had the total flight time of more than three thousand hours. He had made a number of flights to Hmeymim air base in Syria. Navigator Alexander Petukhov was awarded with the Order of Courage for landing an uncontrollable Tu-154 airplane in 2011.
According to experts’ estimates, Tu-154 aircraft do not fall apart in the air for no reason. The plane was designed to withstand airborne loads that dramatically exceed common flight loads. The aircraft has a three-time margin of safety of all systems. Ageing and metal fatigue after replacement of spare parts is not critical for Tu-154.
The aircraft was crashing at a flight speed of about 300 km per hour, at an altitude of about 1,200 meters. If there had been an emergency on board, the crew would have reported it, even 15-20 seconds would have been enough for that, specialists said.
Many experts note that the nature of the fragments and their dispersal over long distances say speak of an explosion on board. For example, the rack chassis was found in the water. This part of the plane retracts immediately after take-off and remains in the gondola during the flight. Was there something in the gondola that caused the landing gear of the aircraft to separate?
