“After combat duty, the Su-35S fighter was sent to ordinary (training) flights, namely for "sparring" in aerial combat (with the Su-30SM). The missiles were removed from the Su-35 but due to someone's oversight, the fighter plane’s cannon’s were not disarmed. 
The  Su-35S and Su-30 practiced aerial combat, the Su-35S was supposed to perform photographic shooting, but instead fired a real volley from a cannon at the Su-30 and demolished that little "plumage" (empennage) . The crew of the Su-30 successfully ejected, and the pilot of the Su-35S, after all that happened, was a little shocked as follows from the message.”
