Reporting from Moscow — The plane crash that killed Polish President Lech Kaczynski on Saturday gutted a nation's leadership and silenced some of the most potent human symbols of its tragic and tumultuous history.
It was, in a sense, a nation colliding with its past: The aircraft ran aground on a patch of earth that has symbolized the Soviet-era repressions that shaped much of the 20th century, near the remote Russian forest glade called Katyn where thousands of Polish prisoners of war were killed and dumped in unmarked graves by Soviet secret police in 1940.
The toll cut a swath through Poland's elite. The 97 dead included the army chief of staff, the head of the National Security Bureau, the national bank president, the deputy foreign minister, the deputy parliament speaker, the civil rights commissioner and other members of parliament.
Also aboard the plane were war veterans and surviving family members of Poles killed by the Soviets. There was 90-year-old Ryszard Kaczorowski, Poland's last "president-in-exile" during the Soviet years. And Anna Walentynowicz, the shipyard worker whose dismissal in 1980 sparked the Solidarity union protests that eventually led to the collapse of Polish communism and made the symbolic first chink in the Berlin Wall.
And of course, Kaczynski, a former Warsaw mayor who had been imprisoned for his opposition to communism.
"The contemporary world has not seen such a tragedy," said Polish Prime Minister Donald Tusk, who as head of government holds the reins of power in the country. He called for two minutes of silence at noon Sunday.
The pavements of central Warsaw were transformed into a sea of light as late-night mourners burned thousands of candles. On Pilsudski Square, a trail of flickering flames stretched more than 50 yards from the Grave of the Unknown Soldier to the towering white cross marking the site where Pope John Paul II first said Mass to his compatriots in 1979.
Flying on a 26-year-old Soviet-designed plane, the presidential delegation was headed for a Roman Catholic Mass to mark the 70th anniversary of the deaths at Katyn. It was to be a tribute to long-smothered truth.
The massacre was denied for decades by the Soviet Union, and even today Russian reluctance to open the investigation files on the Polish prisoners remains a deeply sensitive topic between Moscow and Warsaw. To many Poles, the very name Katyn is shorthand for decades of secret grief and impotence in the face of Soviet power.
"I just have this feeling that Katyn is a sort of diabolical place in Polish history," said Tomasz Lis, a prominent Polish journalist and author. "It's just unimaginable; it's horrible."
As the news spread, a shiver of repulsion ran through a shocked Poland.
"This is unbelievable; this tragic, cursed Katyn," Kaczynski's predecessor, Aleksander Kwasniewski, said on Polish television. "It's hard to believe. You get chills down your spine."
The tragic irony of the crash was so extreme that it seemed destined for conspiracy theory. Russian officials were careful to pledge in the first hours to closely involve Poland in the investigation. Russian Prime Minister Vladimir Putin, rushing to the scene of the crash, announced that he would personally head the inquiry.
Poland was invaded by the Soviet Union during World War II, and lived for decades under Moscow's domination. Long after the fall of the Berlin Wall, ties with Russia remain strained by old anxieties over independence.
As the presidential plane winged toward the western Russian city of Smolensk on Saturday morning, thick cords of fog wrapped the city. On the ground, air traffic controllers urged the crew to land either in Minsk, the capital of Belarus, or in Moscow rather than risk navigating the fog, Russian officials said.
But time was pressing. The crew decided to risk the landing, and ignored the instructions from the air traffic controllers, the Russian air force said.
"The Polish presidential plane did not make it to the runway while landing," Smolensk region Gov. Sergei Antufyev told reporters. "Tentative findings indicate that it hit the treetops and fell apart. Nobody has survived the disaster."
On the ground, about 1,000 people, many of them Poles, were milling around the memorial site. A Polish priest was to say Mass once the presidential delegation arrived.
"We were getting ready for the Mass and everybody was expecting the president to arrive any minute," said Yan Rachinsky of Russia's Memorial human rights group. "Suddenly people started talking quietly about something. There were many concerned faces. . . . Soon people started running around and talking to each other. Everybody was wondering what was going on. It was an atmosphere of tension."
The priest led a prayer. Then the Polish ambassador stepped up to break the news. The presidential plane had crashed, he told the crowd. There were no survivors.
"It was a moment of complete shock," Rachinsky said. "We were standing there speechless. We couldn't believe it."
