    How could they, since they are tumbling?
    OTOH, this seems to explain how they could bring most down in a controlled way with the available fuel: Lower the orbit, let the satellite tumble and the atmosphere do its work for a year, then regain control and give them the final kick.
    
    The decay rate surprised me.
