Polish Commission for re-investigation of the crash of Tu-154 of Polish President Lech Kaczynski claims that the TNT explosion which was allegedly the cause of the crash, the plane was laid during repairs in Russia.
The Tu-154 Kaczynski on 10 April 2010 crashed while landing at the airport "Smolensk-North". Onboard there were 96 persons: 88 passengers and eight crew members flying at the mourning events in Katyn. They all died. The interstate aviation Committee in 2011 issued a final report on the results of technical investigation according to which the immediate cause of the crash is recognized as the crew's decision not to leave on spare airdrome, and the system reasons - deficiencies in flight operations and crew training.
