[105% throttle settings]
I'm not a Space Cadet, but a few questions keep throbbing:
1. Is it *necessary* to launch at 105% power? If not, it seems that such
settings create an unnecessary risk, sort of like routinely accelera-
ting your car with the pedal on the floor. On the other hand, if it
IS necessary, that suggests that the launch device was deliberately
"underdesigned." What's the story here?
2. How closely related is rate of burn-through (assuming it occurs, which it
did) to power level? If power levels had been set within the limits
*intended by the design* would it still have burnt through, perhaps
later in the launch path?
(R)eply at your own risk...
