I thing thah main aim of the "Test manenever" was back transfer of fuel and oxidizer. It is not fully clear why the ODU engines of either SM or FGB were'nt used. My guess is that using Progress engines avoids extensive contamination of Module's surface. Because Progres is on X axis of station, the resulting moments on ISS construction are almost the same. > ------------------------------ > Jonathan T.
