Of course, *all* orbits are actually conic sections. Buit AO-40 
frequently has curliqueues in it's *ground* track because its orbit is 
highly eccentric; the difference between apogee and perigee is large. 
While it's lofting up (and slowing down) through apogee, the Earth is 
turning beneith it, with the result that the ground track traces out 
those little whirligigs.

 Ever play with a Spirograph? :-)
