On 10 April 2010, a Tupolev Tu-154 aircraft operating Polish Air Force Flight 101 crashed near the Russian city of Smolensk, killing all 96 people on board. Among the victims were the president of Poland, Lech Kaczyński, and his wife, Maria; the former president of Poland in exile, Ryszard Kaczorowski; the chief of the Polish General Staff and other senior Polish military officers; the president of the National Bank of Poland; Polish government officials; 18 members of the Polish parliament; senior members of the Polish clergy; and relatives of victims of the Katyn massacre. The group was arriving from Warsaw to attend an event commemorating the 70th anniversary of the massacre, which took place not far from Smolensk.

The Tupolev Tu-154 is a three-engined, medium-range, narrow-body airliner designed in the mid-1960s and manufactured by Tupolev. A workhorse of Soviet and (subsequently) Russian airlines for several decades, it carried half of all passengers flown by Aeroflot and its subsidiaries, remaining the standard domestic-route airliner of Russia and former Soviet states until the mid-2000s. It was exported to 17 non-Russian airlines and used as a head-of-state transport by the air forces of several countries.
