Having now seen the map and the flight path of the Su24's, this is quite simply imho a message to the Russians.
Putin now knows that if he pissed off the Turks, they will hit back and screw the consequences.
Putin is a bully and a piggin very clever one at that.
I've said before on other threads that he has the west by the balls and that stands imo.
In fact, it wouldn't surprise me if he knew that sooner or later, this would happen

Now it has happened, you can be sure that he will turn it around to his advantage in some way

How about using it to destabilise NATO ?
Maybe pop over the border and help himself to a mile or two of Turkish land ?
Turkey spits its dummy out and invokes article 5 and waits for the rest of NATO to run to his assistance.
The yanks say no thanks and run away.
Everybody else sit around the table and ask the UN to write a strongly worded letter of protest

You can bet your life that after what those vile scum did to the aircrew of that Su24, vlad WILL find a way to hurt the Turks, by hook or crook
