The incident is very interesting. Part of me, the dark sick part, says cool!. I thought the days of air to air combat were over.
The Su-24 (Fencer)is a very old airframe, a bit older than the F-16 fighting falcon. It is surprising the Russians, with all their new super badd-ass fighters are actually using these in combat.
The Turks probably used aim-9s,(sidewinder) about a $75K missile. These are a great value. I'll be sorry to see the F-16 leave our inventory. Other than the P-51, it is probably the best, all around, combat aircraft ever built.
You will probably see more advanced Russian planes entering the fray.
