Lucky Turkish Top guns !!
What a chance the F-16Cs were just right there at the very right moment during those (alleged, still not proven) 2 x 7 seconds (or unique few seconds) lasting air space violation(s) and, after the (also alleged) 10 warnings, managed to
1. put themself in firing position,
2. then get an AIM-9 lock on,
3. and finally fire the sidewinder on this Su-24 which was probably already quite far, out of Turkish air.
Comic books hero "Lucky Lucke" usually manages to do that ; shooting faster then his own shadow.
If some people were not dead, I would conclude with this humour point.
But regarding the situation it is just sensless,
Or maybe we all would beter wait until more information emerge (if it does one day...). I guess there are just too many hypotheses and speculations while almost nothing proven, from both sides, right now.
