Thanks for the info. It would be nice to hear about the other plane. The 25th is just starting in Russia, hopefully it's not a sign of things to come elsewhere.
This type plane has a range of 2100 to 2400 miles, and the plane went missing about 140 km from Rostov where it was to land.
It's 1031 statute miles from Rostov to Athens.
All this from the thread about the planes, linked above. (From a couple of different posters.)
Sure hope Italy and Greece are on alert!
