Huntzinger" (CCL-S)Other B-70 tidbits (recalled from my Undergrad research paper) The problem of supersonic heating was "resolved" by utilizing the fuel supply as a heat sink. Reportedly, if the fuel temperature was above "X" degrees, takeoff was denied. Also on fuel, they (I assume GE) "had to develop" a new fuel to provide greater power for the system (see last week's discussions on thrust/weight) and had developed a probably very expensive **BORON** based fuel. Any ideas/comments on why the boron in the fuel? I always had taken this info. at face value & shrugged when it came to how/why. -hummer
