Re: AO40: status



Here is a top view of what I was talking about a split seam along one of
the vertical edges of the exterior of the satellite:

                ------------    .../\\//..
             /               \   .//|//..  <== escapiing gasses
           /                   \  |/|/
         /                       \//
        |                         / <== Rupture along seam
        |                         |  
        |                         |    |
        |                         |    |
         \                       /    /
           \                   /   |/_   <== resulting torque
             \               /
