Smolensk Crash: Evidence for Explosion

Smolensk Crash: Evidence for Explosion

1. Executive summary

January 22, 2015

10 April 2010 Polish Air Force Tu-154 crashed near the city of Smolensk, Russia, killing all 96 people on board. These included President of Poland Lech Kaczyński and his wife Maria, former president Ryszard Kaczorowski, the chief of the Polish General Staff and other senior Polish military officers, the president of the National Bank of Poland, Poland’s deputy foreign minister, Polish government officials, 18 members of the Polish parliament, senior members of the Polish clergy, and relatives of victims of the Katyn massacre.

Excessive vertical rate of descent caused that the aircraft was too low as it approached the runway. When the pilots realized severity of situation they tried to perform go-around maneuverer. The aircraft started to climb reaching the estimated rate of climb around 1181 ft/min (6 m/s) however on the height of 19-22 feet (6-7 m) the left wing hit the large birch tree with a trunk 12 to 16 in (30 to 40 cm) wide. That ripped off about 18 feet (5.5 m) of the left wing, including the left aileron. The resulting asymmetrical lift caused an uncommanded roll to the left. Within 5 seconds, the aircraft hit the ground in the inverted position (150-160° of roll) instantly killing all abroad. Continue reading “Smolensk Crash: Evidence for Explosion”
