We now have size and mass for all of the payloads, so their dispersion
can be seen at:

Positions relative to the TLE provided by Dr. Langley and OBJECT B can
be seen here:

And finally, since someone asked for a Gabbard plot, that can be found at:

It doesn't seem to suggest an explosion.
Here's hoping we get a much clearer picture soon! - TS
