Most interesting, there was no coverage of this in RG.ru or TVZvezda.ru. The Russian Ministry of Defense only had a standard blurb about Zapad 2017 and a plain vanilla video, Best moments of Army Games-2017. President Putin also released only a standard blurb here.
The Moscow Times had this, Pilot Not in Control of Gunship That Misfired on Zapad Bystanders — Vedomosti.
Life.ru published the cockpit video.
VKontakte published the aftermath video originally, according to the RT report.
On September 16, 2017, a pair of Ka-52 attack helicopters, commanded by Lieutenant Colonel A. V. Smachtin and Lieutenant-General A. S. Volkkov, started at Pushkin Airport in the Leningrad area near the Lusian polygon for drills and demonstrations. At 14:47 pm at a height of about 50 meters and a speed of 200 km / h, crew commanders were given permission to conduct the West 2017 exercises to take the battle course and prepare for the shooting. At this point, three unmanned S-8 aircraft missiles spontaneously fired from a machine under the command of Lieutenant Volckov. Burned rockets detonated in close proximity to viewers: military attachés, military industry experts and journalists. Three people were wounded and two military trucks damaged.

Through an in-depth analysis of the available video material, volunteers from the InformNapalm international intelligence community found that one of the helicopters had fired three rockets, not just one, as many media reported. The RB-341V Leer-3 Unmanned RB-341V Leer-3 Controller (aerodynamically deployed jammer of the GSM Mobile Terminal Subscriber Terminals) was identified among the damaged trucks. Also included were Orlan-10 drones, the P-230T Command Staff Vehicle, the P-260T Redut-2US Control and Communication Kit.
