You gotta remember, the planet is not perfectly round, so as it moves towards the equator it gets closer to the ground, as it then moves past the
equator it appears to gain altitude. I'm no scientist but thinking logically usually helps..
I remember watching this as the Russian satellite was falling, it was sling shooting up and down for days before gravity sucked it to the ground
