Nevertheless, the JIT said that the prosecutors do not link the MH17 downing to the Russian state of Russian citizens' actions.
The team said that there are some 100 people involved "in one way of another" in the MH17 plane's downing.
Almaz-Antey arms manufacturer said that technical details of the Malaysia Airlines Boeing 777 have not been taken into account by the JIT's probe. Three simulations of the MH17 crash carried out by the Russian arms manifacturer confirm that the missile had been launched from Zaroschenskoye town controlled by Ukrainian forces.
"The conclusions by the Joint Investigation Team announced today do not have sufficient technical evidence to support claims allegations that Russia was somehow involved in Malaysian Boeing catastrophe in summer of 2014," Mikhail Malyshevsky, an adviser to Almaz-Antey general director, said.
The way the MH17 plane was damaged proves the Almaz-Antey's findings, the company said. The Russian company provided the Dutch-led investigative team with all documents it has, including those that had been top secret.
When simulating the MH17 downing, the Netherlands used data about an American missile that is different from the BUK's missile, the Russian arms manufacturer said.
There is a possibility that the Malaysian MH17 Boeing passenger plane was downed by a Buk missile in eastern Ukraine in 2014 by mistake, Russia's Almaz-Antey concern said.
"The possibility that it was downed by a mistake made by Buk air defense system operator cannot be ruled out." "It could have been poor training of the crew, or unreliable tracking data, any tragic mistake was possible, including a mix-up during the loading of a missile — combat version instead of a dummy variant."
A representative of the radar-producing plant, Lianozovskiy Electromechanical plan, said that radars can not notice objects flying toward it. Radars can not see planes in a cloudy sky as the speed of a plane is higher than that of a cloud, Viktor Meshcheryakov explained.
The radar system could not have noticed a rocket fired from the south of the MH17 crash site, the town of Zaroschenskoye, according to the expert. If the missile had been fired from Pervomaiskiy town controlled by the Donbass militia, the radar would have 90 percent noticed it.
The Malaysia Airlines flight MH17 was en route to Kuala Lumpur from Amsterdam when it was downed over eastern Ukraine on July 17, 2014. All 298, including 80 children and 15 crew members, were killed.
