." Later it was determined that the plane crashed near the village of Sukha Balka.

"At an altitude of 11 500 metres (37,000 feet), the aircraft sent three SOS signals, dropped sharply in altitude and sent another SOS at 3000 metres (9,000 feet)," said Anatoli Samoshin, vice Flight Operations Director at Pulkovo Aviation Enterprise. There were no other communications.

Approximately 260 rescue personnel arrived at the scene which was blocked off by the authorities as the field of debris and bodies was about 400 meters in length. On Wednesday, Ukrainian emergency service personnel concluded their search for bodies, confirming that 170 people perished in the accident. Due to the extensive crash forces and post-accident fires, rescuers believed that it would be very difficult to identify the majority of the victims on site. The aircraft crashed in a swampy area, breaking up on impact. The search for black boxes

, which was interrupted for the night, concluded in the morning when both recorders were found. The flight recorders were later transported to Moscow for analysis.

The crash was witnessed by a local farmer and a young couple seeking shelter from the rain. They told reporters that they saw the aircraft falling out of the sky and that it burst into flames upon hitting the ground. They could see people in a number of seats that were thrown out of the aircraft on impact, but none showed any signs of life. A man living in a nearby village was able to make a short video of the crash with his cell phone.

Early reports suggest that Flight 612 may have been caught in a thunderstorm; immediately prior to the crash, the pilots notified air traffic control that they were experiencing severe turbulence. According to the residents of a nearby town, the weather at the time of the crash was violent enough to cause power outages and cell phone disruptions on the ground. Authorities on the scene have speculated that the aircraft was struck by lightning which may have initiated an onboard fire. However, another theory has since been proposed.

The MAK final report concluded:

The cause of the crash of the Tu-154M RA-85 185 airlines "Pulkovo" was the aircraft entering in manual flight mode, supercritical angles of attack and stall mode with the subsequent transition to a flat spin and collision with the ground with a large vertical velocity. In the absence in the Flight Manual (RLE) and crew training programs of recommendations on peculiarities of piloting in the longitudinal channel in manual mode and using the trim mechanism, and inability to work on the skills of piloting the aircraft in hand mode at high altitudes and angles of attack due to the lack of appropriate simulators, the crew while avoiding area of thunderstorms and turbulence allowed the aircraft to enter pitch oscillations exceeding the operational range of angles of attack. Lack of control over flight speed and not following the instructions of RLE to prevent the aircraft entering stall mode and poor crew coordination allowed the situation to escalate into a catastrophic one.

Victims

On their corporate website,http://www.pulkovo.ru Pulkovo Aviation Enterprise posted a short statement and passengers list confirming that there were 160 passengers and 10 crew members aboard the aircraft. Among the passengers, 115 were adults and 45 were children under 12 years old. Among the adults, 8 were over 60 (including a 92-year-old woman who flew with one of her grandsons and his wife and two of her great-grandchildren). Earlier reports by the media and by the airline indicated that 159 passengers were on the flight, 39 children under 12 and six infants under 2 years of age. Some other sources reported that plane was carrying 171 people: "The crew sent the May Day signal
