Shotone,
Several posters have accused Turks of poor English which is ignorance as it is just not true. Virtually all Turkish Military crew will have gone to a Military High School and studied English extensively- in an American style. That much is obvious by pronunciation of some words.
The comms go on 121.5mhz VHFand I and other civilian airliners hear them all the time, and also on 243mhz UHF.
If the Su-24 did not listen to this, or they couldn't, they really had no place being in the air in this part of the world!
