The downed fighter jet was warned 10 times in 5 minutes according to a statement released by the Turkish Armed Forces
In what language?
One presumes in English, as that is likely to be the only common language. But in my experience the Turkish military English is as bad as Russian military English. In which case, there is ample room for confusion, especially when a military pilot is very busy planning an active sortie.
If the Turks are so jumpy that they cannot realise the potential problems, and observe rather than engage, then they are not very clever. Did they really think this aircraft was about to attack Antakya? Frankly, the initial analysis suggests that trigger-happy Turks have (predictably) precipitated an unesessary international incident.
