On April 10, 2010 an unanprecedented tragedy happened in Smolensk Russia. A presidential Polish Air Force Russian made Tupolev plane TU-154 with 96 passengers on board exploded in the air as it was approaching the landing strip landing. 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. They were en route from Warsaw to attend an event commemorating the 70th anniversary of the massacre; the site is approximately 19 kilometres (12 mi) west of Smolensk.
