I guess we’ll just have to wait and see what, if anything, Boeing find out of the ordinary.

Don’t forget that the 777 has something called Thrust Asymmetric Compensation (TAC) which recognises a difference between the two engines’ fan speed and hence automatically adjusts the rudder to compensate during, for example, an engine failure.

Although, unlikely to be the cause of this problem, it could be something to take into account.

So theoretically a software failure of this system could of caused such an incident?
