Well, I don't doubt what YOU have experienced any more than I doubt what _I_ experienced. It was definately effecting the performance of the aircraft in the first incident I described. Oh I know about Boeing and their ice shapes in the certification process, but after I saw first hand that ice can form and effect the performance, I acted accordingly for the rest of my career. I just think it's stupid to have that nice heater in the tail of the 737 and not put it to use when needed.
