Re: Nuclear-powered spacecraft plan feared



Radsafers:  Does the shuttle have DU counterweights like big airplanes have?
"Big airplanes" have them to dampen flutter (aerodynamic/structural-coupling-vibrations). I am not knowledgeable of the shuttle's flight regime' since it is so far beyond anything else flying, but it is a very "stiff" structure that spends very little of it flight time in the atmosphere. Even so, why would it matter?  DU is just heavy dirt used for dead weight? The earth is "covered" with it and we do alright.
