 Russian A-50 plane was hit by Russia's own air defenses over the Azov Sea. A rare $400 million Russian early warning and control aircraft and an Ilyushin plane were hit by Russia's own air defenses over the Azov Sea. Multiple Russian telegram channels reported that Moscow lost a Buriev A-50 Schmel NATO reporting name Mainstay in a case of friendly fire. It was also reported that the Ilyushin Il-22M airborne command post was damaged. The Raibar telegram channel, which has links to Russia's defense ministry, said the aircraft could have been struck in friendly fire from Russian air defense. Ilya Ponomarenko, the Ukrainian journalist, said on X that if confirmed it would mark the biggest Ukrainian air victory of this war so far. The Raibar telegram channel says that there are not many A-50s and the specialists on them are generally unique. If an aircraft of this type is hit the crew will not be able to escape. The option of friendly fire from the Russian air defense is not at all theoretically impossible. Unfortunately for two years there were enough such cases but there was no tendency to correct it at all. The channel added. It is noted that the following questions arise regarding this whole situation. Why is the broadcast of the pilots of the surviving Il-22 open and written by everyone who is not too lazy? Why do Ukrainian formations still almost instantly learn information about any casualties of the Russian armed forces? If this was the work of Ukrainian air defense then where were the launchers driven so that the Azov Sea was in the affected area? The channel added. Russian military correspondent Yuri Kotenok wrote that Russian air defense systems are not working normally. It was noted that this is not the first case of Russian aircraft being shot down by its own anti-missile systems. Russian military correspondence wrote that a plane was shot down on October the 6th, 2023. British intelligence also wrote that on September the 28th, 2023 the SU-35S aircraft was shot down by Russian air defense systems in the Tokamak region. The Rybar channel said that poor communication and broken recognition system led to the accounting of the Russian air defense systems for the SU-34, SU-35S and SU-30SM aircraft as well as the Ka-52 helicopters which have been lost since the spring. Another Russian telegram channel, Voyeni Osvedomitel reports that Russian planes are often attacked in the rear.
