According to the head of the District Military Prosecutor's Office in Warsaw Ireneusz Shelonk, they are accused of creating the situation that led to a direct hazard and unintentionally causing the air crash.

As reported, Warsaw is planning to call the controllers for questioning as suspects.

According to the report, the Polish Military Prosecutor's Office still said that the main reason of the tragedy was the insufficient qualification of the crew members of the crashed Tu-154 and their mistakes in assessing the situation.

"Among the team of the aircraft only the engineer had the skills that were necessary to service the aircraft, and the captain of the plane did not have the appropriate training that would allow him to land the plane in bad weather conditions, and he wrongly assessed the situation. The crew repeatedly violated instructions, [and] the pilots ignored reports of dense fog in the area of the airport," the report reads.

As reported earlier, the plane of the Polish president, which was carrying 96 people, including Lech Kaczynski, crashed while landing at the Severniy airfield in Smolensk due to heavy fog and low visibility. All 88 passengers and eight crew members were killed.
