On April 10, 2010, a Polish government aircraft attempted to land in dense fog in Smolensk, western Russia. Lech Kaczyński, then Poland’s president, was on the plane. He was leading a delegation of the country's military and political top brass. They were traveling to Katyn to commemorate the seventieth anniversary of the murder of 20,000 Polish officers and prisoners of war by the Soviet Union's secret police.
