   One thing to note is that at hypersonic speeds it is impossible to achieve a   
   high lift/drag ratio. What this means is that much of the impulse experienced   
   by the aerobraking spacecraft will be drag, with a small amount of lift.   
   Because of this I think it    
   will run out of orbital velocity before it gets much of a change in orbital   
   plane.
