Flying a 777 this weekend?

What pilots are saying about the BA 777 accident

This website indicates that some pilots speculate that fuel contamination is behind the Heathrow 777 crash this week.

However, the initial accident report says this is what happened:

Initial indications from the interviews and flight recorder analyses show the flight and approach to have progressed normally until the aircraft was established on late finals for Runway 27L.

At approximately 600ft and 3km (two miles) from touch down, the Autothrottle demanded an increase in thrust from the two engines but the engines did not respond.

Following further demands for increased thrust from the autothrottle, and subsequently the flight crew moving the throttle levers, the engines similarly failed to respond.

I wouldn't have thought that a fuel contamination would lead to this problem in both engines at exactly the same time.

Its sounds more like a problem with the avionics (if that is the right word for the electronics involved in control of the engines.) And if I am right at this guess, I wouldn't want to be flying in a 777 right at this moment.

I love making guesses in fields I know next to nothing about.

UPDATE: this article in The Times lists the possible causes, and yes, a computer/software problem is one of them.
