On April 2nd, 2012 an UTair turboprop with 43 people on board was to fly to a Siberian town of Surgut but crashed within minutes of takeoff from Tyumen killing at least 31 people.
Those who survived were helicoptered to a nearby hospital. It was later announced that some of them died.
The impact split the plane into three pieces.
Investigators focus on the possibility of a technical malfunction as an eyewitness reported seeing smoke coming from the engines as the aircraft came down. It can be also blamed on the pilot's error.
