Russia's presidential representative in the Central Federal District, Georgy Poltavchenko, said late April 10 that the Polish flight crew of the crashed presidential plane had been advised by Russian air traffic controllers to deviate from their flight plan to Smolensk and land in Minsk or Vitebsk in Belarus. This was later echoed by Russian Transportation Minister Igor Levitin, who said that the decision to land the plane was taken by the Polish pilot, which has been confirmed by flight recordings recovered from the crash site. According to Levitin, the visibility at the airport was 400 meters due to heavy fog, whereas the required landing visibility is at least 1,000 meters. Levitin also said the two flight recorders will be taken to Moscow where they will be examined in cooperation with Polish investigators. According to STRATFOR sources in Poland, the decision to land in Smolensk, and not in Belarus, may have been influenced by the fact that the ceremonies marking the 70-year anniversary of the Katyn massacre were due to take place within an hour of the supposed landing. In addition, the Tu-154 presidential plane was built in 1990 and had recently been serviced in Russia. In January 2010, Russian airline Aeroflot ceased to fly the model, which was designed in the 1960s. Polish President Lech Kaczynski — who, along with 96 others died in the crash — was known to take risks, demanding that his pilot lands his presidential plane in Tbilisi during the 2008 war between Georgia and Russia. His pilot at the time refused to land in a war zone, instead diverting the plane to Azerbaijan. According to sources in Poland, that pilot was reprimanded and never flew with the president again.
