It sounds like an attempted hijacking.
I'm sure the Russians are just giddy over the latest pronounced support of manpower and materials to assist Iran in it's nuclear missile effort right about now......
This is my very first post. I hope it's in the right place. Fox news is reporting that the second plane sent a hijacking alarm before it broke up in mid-air. I wonder if it was a bomb that caused it to break up or if terrorists were at the controls and flew faster than the maximum safe speed, putting too much stress on the aircraft. One of the planes was heading to the city where Russian President Vladimir Putin is vacationing.
