   No, denying total costs is ludicrous.  How much does 20% more fuel cost?   
      
   How much does the Ballon cost?   
      
   How much to recover the Ballon cost?   
      
   If you don't recover it, how much does the insurance of a free flying ballon   
   that could land anywhere cost?   
      
   How much flights are lost because of a windy day that prevents lanuching the   
   ballon?   
      
   How much are extra development costs to ensure that the rocket engine lights   
   100% of the time when released from ballon.   
      
   What is your fastest turn around time between ballon lanuchs.
