Well, it would seem that the aircraft's crew became disorientated in a storm. They didn't follow ATC's instructions on departure. ATC were trying to steer them around heavy turbulence after the aircraft had departed Beirut and the crew were turning too late or at times in the wrong direction (at times towards the fast rising mountains East of Beirut) It wasn't a bomb that brought down that aircraft- no explosive materials were found anywhere on the wreckage and initial reports by eye witnesses of explosions were later put down to lightning.
The CVR also didn't pick up any evidence of inflight break up or explosion.
The reports from ATC clearly show that the crew didn't (or couldn't) follow heading directions and they were performing erratic altitude changes. It all boils down to pilot error and/or fatigue. Ethiopian clearly didn't want to accept the facts because it puts their training and crew in a bad light despite the overwhelming evidence of flight crew mismanagement and inexperience.
Two aircraft left just before ET
's doomed flight, both completing the manoeuvre to avoid the storm and both arrived at their destination.
Lastly, conspiracy theories exist about every major event. Look at the conspiracies for 9/11 for instance.
In a politically charged country like Lebanon it wouldn't take long for these false allegations and rumours to start, especially if it's in one group's interest to stir trouble. Unfortunately, this tragedy could have easily been avoided by proper airmanship.
