    If the tether broke on Aug.30 2006, and ignoring the oscillation recoil 
    effect mentioned,
    the mass center was moving 7109 to 7614 m/s; end masses 2 km above/below 
    7111/7107 vs. 7616/7612 m/s.
    (I got the following vectors from Track16, and multiplying/dividing:
    
     4369.7 -5568.9  739.0  2.26180  2.66965  6.76488 (7.616)
     4367.3 -5565.7  738.6  2.26053  2.66815  6.76108 (7.612)
    -4677.6  5970.5 -754.4 -2.12900 -2.46904 -6.31997 (7.111)
    -4675.2  5967.3 -754.0 -2.12788 -2.46774 -6.31665 (7.1076)
    
    Vec2TLE gives the following elsets, which might be used for full-orbit 
    searches, but they must probably be integrated to account for continuing 
    increase (or oscillation?) of eccentricity.
