Some questions then. As a fuel guy, do you conclude that the (permitted) water was the culprit? Was it an accumulation of atmospheric moisture via venting? What about the conclusion that the ice was 'soft' and 'malleable'.
Also, Pinkman, what of Boeing's 60 years experience of turbo (fan) jet performance at levels up to 60k and above? It remains disconcerting to me, probably to others that the industry seems to be a bit coy with the purported 'mystery' of this event.
What about the 'slurry' theory from Airfoilmod? Some combination of waxy fuel and microcrystalline water-ice? Have you seen this before?
