According to a leaked Russian government document external link, a Russian MiG-31 supersonic interceptor aircraft was mistakenly shot down by “friendly fire” during a training flight near the Telemba proving ground in Siberia almost two years ago.
The incident in question had happened on April 26, 2017. At the time, the Kremlin said that the plane had been on a training exercise, but offered no additional details about the mishap. Both of the Foxhound’s crew survived the incident. In the leaked report, investigators concluded that the crew in the plane that got shot down had improperly followed procedures, allowing them to stray into the potential line of fire during the live-fire exercise.
It also faulted aviators flying the other Foxhound for turning on their Zaslon-AM’s fire control function at the wrong time, cueing an R-33 missile right at their wingman.
