Russians don’t have air superiority.
They have a couple dozen aircraft, at best, in the area. The Turks outnumber them 10:1 in aircraft in range. The Turks can also attack the Soviet airbases in Syria with artillery rockets in range, and from the sea. It’s also not clear who has the technological advantage.
This sort of escalation is very dangerous.
S-400 and other air-defense systems would make Turkish airplanes over Syria very risky.

As for the number of Russian aircraft in Syria, 50+ for sure, one can probably find current numbers easily. My guess that they will be unopposed over Syria.
“Turks can also attack the Soviet airbases in Syria”
In 1970, referring to German bases as Nazi bases would make one sound ...uninformed at best. The USSR ended about 25 years ago except for a few people.
We all miss the cold war days, we really do. But you need to let it go. It isn’t good for you to live in the past. As for Turk rocketry, you might want to check with who is the master of rocket warfare there. It isn’t Turkey. The minute Turkey launches a rocket at Latakia, almost all of Turkey instantly becomes an S400 enforced no fly zone.
