Polish military prosecutors have opened an investigation into the plane crash that claimed the lives of Polish President Lech Kaczynski and dozens of the country's top officials, Polish Attorney General Krzysztof Parulski said on Tuesday.
"The Military Prosecutor's Office is carrying out an independent investigation [of the accident]," he said.
Polish TVN24 TV channel reported earlier in the day Russian and Polish specialists will finish on Wednesday or Thursday analyzing the data contained in the black boxes of the plane that crashed in western Russia killing the Polish president and 95 others.
It also said that contrary to initial reports, an examination of the flight recorders revealed that the crew had made two, not four attempts to land.
The flight recordings also indicate the Polish pilots did not report any technical problems on board.
Russian government officials said the bodies of 48 people had been identified and a special plane from Poland was expected to take the coffins home later on Tuesday.
The delegation of top political and public figures was on its way to pay tribute to some 20,000 Polish officers executed by Soviet secret police in 1940.
Poland has declared a week of national mourning.
