See?  I *TOLD* you the propaganda would be effective.  The answer to your
question is: That flying piece of cotton will have approximately as much
kinetic energy as was originally stored in the flywheel.  That follows from the
law of conservation of energy.  Just because it's fluffy doesn't mean it's not
dangerous, given that it's going fast enough.

understanding of astronomy is purely at the amateur level (or below).  So
unless what I'm saying is directly related to VAX/VMS, don't hold me or my
organization responsible for it.  If it IS related to VAX/VMS, you can try to
hold me responsible for it, but my organization had nothing to do with it.
