Hi
On a news report tonight it was suggested that just prior to takeoff there was some form of engine problem on the ground that was dealt with by staff on the ground although there were no further details.
The interviewer interviewed an expert from Britain who suggested that a fan blade may have been flung off and done a great deal of damage. He suggested that on each wing the two engines are mounted close to each other which would not help.
