Jet was shot down with ground based Anti - Aircraft artillery round, with effective range of about 400 - 500 meters. Initial report from Turkey was flat denial "aircraft lost all communications after first few minutes into the flight and was lost due to technical malfunction". Syria military reports that the jet flew at less than 100 meters, an altitude where radar radio waves do not operate due to limitations of radio waves. Nor can jet communicate with home via radio due to same limitation. Sending military jet at this altitude in a foreign country constitutes crime of aggression, plain and simple. Russians were handed over all aces to slam NATO in Haague for this war crime and walk away with a jucy verdict. And will be damn wrong not to do so.
