The presence of a quantity of water in the tanks has been determined. Whilst it would appear to have been small is there any possibility that the location of the water (or ice at that stage) could have become focused/concentrated in one or two particular areas and then gone through to the engines as a slug?
I appreciate that the volume of water present does not appear to have been sufficient to cause the problems experienced.
Could it have been underestimated? Could it have been in the wrong place at the wrong time?
