   There is a very distinct difference between attempting to control _one_   
   hypersonic vehicle controllable under relatively smooth external conditions,   
   versus attempting to control _two_ of them in extremely close proximity,   
   with their shock-waves and plasma-sheaths mutally interacting and   
   impinging on each other, under conditions of very rapidly changing   
   and almost certainly turbulent airflow. The latter case makes attempting   
   to do something as stupid as practicing "touch and goes" on the back of a   
   flying 747 look positively safe and easy by comparison.
