They told me that the plane suffered a strange turbulence in the region where missing.
What passengers describe as "strange" is often just normal, moderate turbulence or aircraft movement. I would pay attention if the flight crew were making the above statement. Not pax.
There was also a breakdown in the electric system of those screens that show a map of Orta flight for each passenger - and for watching movies where too. They surprise because the sky was clear, without clouds, even with sunlight.
AVOD/IFE systems often have problems. It usually doesn't indicate anything sinister.
Someone can explain what would have happened with the Airbus A330?
If you read back over the last 26 or thereabouts pages of postings, you will see a number of intelligent speculative posts (and a large number of truly idiotic ones) about what
might have happened. Nobody, however, can explain what actually
did happen until all the facts are in, and even then maybe not with 100% certainty. We just have to wait.
