I think in these times its best to hope Turkey and Russia can sit down sort the issue of air violation , via communication
Normally shooting down a plane which is mostly a ground based plane , perhaps not even carrying air to air , was perhaps a little bit too much
Flying 1-2 Km into territory or close to it , can happen naturally at Mach 2 flights , and just shows perhaps lack of communication between Turkish - Russian pilots
I still don't understand how the two pilots understood each other's calls if they both speak different language
If Turkish pilot gave out warning in Turkish or English , the Russian speaking pilot may not have even understood the call
Some of the Chinese counter part are stating China-Turkey do not have good relations what is the truth behind that statement which is showing up in this thread?
I think not long ago Turkey was purchasing Chinese SAMs
