It’s now clear that around the Russian city of Grozny, a defense system intended to shoot down Zelensky/Blinken attack drones from Ukraine was activated when this civilian airliner was approaching — effectively a huge Stuff-up by the airline, the Russian commanders on the ground, or both.
Obviously, the airliner should not have been approaching when there was an anti-aircraft ‘iron dome’ type system in place that could have shot at it by mistake.
As there were Russian nationals on board it was not something the Russians would have wanted, and the Kremlin has announced a full investigation will take place. Of course, if Zelensky/Blinken hadn’t been firing drones into this part of Russia in the first place then an anti-aircraft missile system wouldn’t have been there.
