Cause of accident according to Polish report:
“The immediate cause of the accident was the descent below the minimum descent altitude at an excessive rate of descent in weather conditions which prevented visual contact with the ground, as well as a delayed execution of the go-around procedure. Those circumstances led to an impact on a terrain obstacle resulting in separation of a part of the left wing with aileron and consequently to the loss of aircraft control and eventual ground impact”[81]
Circumstances contributing to the accident:[81]
1. Failure to monitor altitude by means of a pressure altimeter during a non-precision approach;
2. failure by the crew to respond to the PULL UP warning generated by the TAWS;
3. attempt to execute the go-around maneuver under the control of ABSU (automatic go-around);
4. Approach Control confirming to the crew the correct position of the airplane in relation to the RWY threshold, glide slope, and course which might have affirmed the crew’s belief that the approach was proceeding correctly although the airplane was actually outside the permissible deviation margin;
5. failure by LZC to inform the crew about descending below the glide slope and delayed issuance of the level-out command;
6. incorrect training of the Tu-154M flight crews in the 36 Regiment.
Conducive circumstances:[81]
1. incorrect coordination of the crew’s work, which placed an excessive burden on the aircraft commander in the final phase of the flight;
2. insufficient flight preparation of the crew;
3. the crew’s insufficient knowledge of the airplane’s systems and their limitations;
4. inadequate cross-monitoring among the crew members and failure to respond to the mistakes committed;
5. crew composition inadequate for the task;
6. ineffective immediate supervision of the 36 Regiment’s flight training process by the Air Force Command;
7. failure by the 36 Regiment to develop procedures governing the crew’s actions in the event of:
o failure to meet the established approach criteria;
o using radio altimeter for establishing alarm altitude values for various types of approach;
o distribution of duties in a multi-crew flight.
8. sporadic performance of flight support duties by LZC over the last 12 months, in particular under difficult WC, and lack of practical experience as LZC at the SMOLENSK NORTH airfield.

Even your own silly article says:
“Earlier this week—on April 8, 2014—Polskie Radio reported that the Polish District Military Prosecutor in Warsaw, Colonel Ireneusz Szelag, presented 1,300 pages of documentation, in advance of the four-year anniversary, ruling out “any possibility that an explosion occurred aboard the Polish presidential plane that crashed in Smolensk on 10 April 2010.†The prosecutor stated, “After analysing 700 samples, experts found no traces that an explosion had taken place aboard the Tu-154 plane… The experts had unimpeded access to the site of the catastrophe, and to the place where the wreck of the plane is being stored.†The prosecutor stated that the investigation would be closed next year, even if the aircraft’s wreckage is not returned to Poland.â€
