They are saying the Israelis used the Russian plane to cover their attack on the Syrian target and draw Syrian AA missiles on it instead of their planes.
Perhaps Israel should stay out of Syria and stop getting the Russians pissed off at them. It is unlikely to end well. The Russians are known for getting revenge.
So... they shot down their own plane, trying to hit Israeli’s. That’s what I thought.
If they fired on a hostile IDF fighter but then lost control of the missile in flight (improperly set up/commanded) or the system simply has no means of commanding the missile in flight (eg. no "midcourse" guidance from the firing battery) then again, it was a very bad call to make with friendly and/or non-combatant aircraft in range. Again, a failure of Syrian AD and possibly indicative of a shortcoming of the Russian S-200 system.
There is almost no-way Syrian AD comes out of this looking like they did everything right and those mean old Israelis tricked them. Sure, the IDF no-doubt employed technical means and tactics to ensure their safety. It seems to me Syrian AD were (are) poorly trained and/or poorly executed their TTP, probably fired when they should not have, and/or fired in a mode they should not have with an emitting friendly AWACS/ELINT in the area.
