MOSCOW, September 22. /TASS/. One more person featured in the criminal case over the October 2014 crash of a Falcon business jet at Moscow’s Vnukovo airport has been freed from custody, a source familiar with the situation told TASS.

"Production director of the airport’s subcontractor company OOO Spetstekhrekonstruktsiya, Anatoly Kruglov, has been released as the maximum allowable term of keeping him in custody expired," the source said.

On the night from October 20 to October 21, a Falcon business jet of the French oil corporation Total staked a snowplow during takeoff from Vnukovo, caught fire and crashed on the runway, killing the corporation’s CEO Christophe de Margerie and the three-strong crew of the jet.

Russian authorities instituted a criminal case on charges of encroachment on the regulations for safe air traffic and safe aircraft operations.
