Sorry Lads. Trawling through all these posts and your honest attempts to vindicate the AAIB's preliminary findings, seriously, what are the odds of ice causing both engines to fail at the same time? One I could understand, but not two.
If there was low fuel pressure to the engines caused by a build up of ice, why was this not noticed? Why didn't the PEK/LHR 777 that day also exposed to low temps did not reciprocate the problem. A mate of mine flying a BA 747 at the same time from HKG said fuel temps were in the amber for some time, but no engines stopped.
The fact that this debate continues proves the ice theory is not convincing.
It is something else.
