Some issues with this article. As pointed out, delta doesn't fly that route. It was in fact a DOD charter from Hahn to kuwait. Second, sensational reporting aside, according to other sources the 764 was transitioning to the Greek fir and was not in contact with them for about 10 minutes when the decision was made to scramble an intercept. Coming so soon after the disappearance of the Egyptian plane perhaps a bit more sensitive than on other days?
I don't know for sure what happened but the cited article is definitely not full of facts!
