tragedy on air

there's been a tragic plane crash outside Athens a few hours back, with 121 passengers and crew all unfortunately dead. the reasons of the crash are not clear as of now, but teh plane (coming from Nicosia, Cyprus to Athens) had lost touch with the airport at least half an hour before it crashed.

the pilots of the two fighter aircrafts that tried to escort it to the airport reported that both pilots had lost senses and there seemed to be no movement in the plane, which remained ungoverned for quite a while. A relative of one of the tragic passengers claims to have received two sms's from his relatie on the plane just before the crash: one mentioning that the pilot is dead and it;s extremely cold in the plane, the second one saying one final goodbye before the crash.

what has happened? noone know 100% as of now. the most common explanation seems to be some kind of mechanical failure which caused decompression in the cabin, with the result of most people dying on air, before the plane landed. the possibility of hijacking has been ruled out early in the process of reporting the news.

there's a lot of explanations to be given still and more details to come to light, but the bottomline is that 121 people died a tragic death today, and answers on why are needed. the relatives and the entire country is in grief.
