In 2010, a plane carrying the Polish president, Lech Kaczyński, crashed near the Russian city of Smolensk, killing everyone on board. It was one of the most tragic moments in modern Polish history. The country’s minister of foreign affairs, Radoslaw Sikorski was one of the first people to hear about it. He’s been sharing his memories of the disaster with Matt Pintus.(Photo: Smolensk air crash wreckage. Credit: Getty Images)
