   one way or another. Obviously the simplest solution is to reel the cable in   
   while reducing thrust to maintain tension, and that's probably the safest way   
   to handle large-angle    
   maneuvers.   
      
   I don't think simply reducing thrust would cause any difficulty... you don't   
   get fouled up until there is NO thrust, or there is a negative thrust   
   component in the direction of the original thrust vector. Otherwise, there is   
   still tension.

   going? You can't just fire the main engine before reeling the crew module out   
   because, well, nuclear rocket in your face, and if you reel the cables out   
   before boosting, what    
   makes the two modules separate? The single-cable-multiple thrusters version is   
   much easier- just ease off the cable brakes as you ramp up the thrust to   
   maintain tension. Somehow there has to be redundancy in case the cable fails   
   though.

    The Revell model was actually based on a real concept proposal, called   
   HELIOS. In this riginal proposal, the crew module fires retro jets to reel out   
   the tow lines. This is probably coupled with chemical separation jets on the   
   propulsion module.
