Russian and Polish investigators held an additional inspection of the area of the Polish presidential plane crash, a spokesman for the Russian Investigation Committee said on Sunday.
Polish President Lech Kaczynski, his wife, and an official Polish delegation of senior officials died when a Soviet-made Tu-154 aircraft crashed on April 10 near west Russia's Smolensk while attempting to land in thick fog, killing all 96 people on board.
The plane was taking them to a ceremony to pay tribute to some 20,000 Polish officers murdered by Soviet secret police.
Vladimir Markin said the investigators, including a deputy chief military prosecutor of Poland, held an additional inspection of the crash site, during which "no fragments of human bodies, parts of the plane or personal belongings of the victims that could have any relation to the investigation of the criminal case were found."
Russian and Polish investigators and experts are jointly investigating the causes of the deadly crash, while Polish military prosecutors are conducting their own investigation.
The head of the Interstate Aviation Committee said on Wednesday that non-crew members were in the cockpit of the Polish presidential plane.
"It was proven that non-crew members were in the cockpit," Tatyana Anodina said.
Ukraine's UNIAN news agency reported on Wednesday a Polish Air Force commander and the Foreign Ministry's chief protocol officer were in the cockpit of the crashed presidential plane.
Anodina said the voice of one person was identified while the others are being identified by Polish officials.
She did not specify the number of people in the cockpit or their identities.
The Interstate Aviation Committee technical chief, Alexei Morozov, said Russian controllers had repeatedly warned the crew of the Polish president's plane of bad weather conditions and landing should be avoided.
"The lead controller warned the crew twice about fog at the airport, visibility of 400 meters, and that landing is impossible," Morozov said.
The committee also said that the plane's crew had no information on navigation or weather conditions at the destination point.
Morozov said the crew had received weather data, which included the actual and forecasted weather in the departure airport, emergency airfields, as well as the weather forecast on the flight route. "The crew had no actual weather or forecast information at the final destination at Smolensk Airport."
