MOSCOW. Sept 3 (Interfax) - Polish officials and Russian investigators have started another joint examination of the debris of the aircraft that crashed near Smolensk in 2010 while carrying former Polish President Lech Kaczynski and numerous other high-ranking Polish government officials, Russian Investigative Committee spokesperson Svetlana Petrenko told Interfax on Monday.
"Under another request for legal assistance by our Polish counterparts, Investigative Committee officials together with officials from relevant Polish agencies today started a new examination of the parts of the plane that crashed in Smolensk eight years ago," Petrenko said.
The investigation has meticulously explored the theory that there could have been an explosion on board the plane, she said.
"However, the multiple tests carried out by both Russian and Polish experts have shown that there are no traces of explosives on the remains of the dead and the plane's debris. It's clear to any specialist knowing laws of physics and aerodynamics that, considering the damage caused to the plane, there could have been no explosion on board," Petrenko said.
