   Musk has confirmed that the booster currently being stand-tested will   
   not fly.

   Musk has said that the first orbital attempt will use cold-gas   
   thrusters, with the hot-gas ones to be used at some later point. I   
   haven't seen anything about how the cold-gas thrusters will be mounted,   
   though.
