From Greek newspaper
According to reports, Greek-owned cargo ship has reportedly says remarked great explosion in the sky in the area of Karpathos. FYI area where last contact took place
"Experts estimate that the fact that the pilots had no time to send out distress signal means that this surprise happened on the aircraft."
MY guess- -- it was not mechanical ! -- assume a missile or bomb on board--if so--- all the technology does not work--I was in Paris a few days ago and remarked that security "looked good" but wondered --was that just a "show" to make the tourist feel safe
every store and hotel required you to open your bag - assume checkers had "0" training
HOPE I AM 1000% WRONG
