Well it (IR 9) might have done if the very high "drag" term (ndot2) in
the elset were indeed due to atmospheric drag. It isn't, of course. The
spacecraft is being manoeuvred downwards and the "drag" term, for the
moment, reflects the manually-induced increase in mean motion and not
the density of the atmosphere at its altitude.
