   Rather old piece of news, but thought I'd bring it forward in case no   
   one has seen it. LC-39A look will continue to change in the not too   
   distant future.   
      
   There is a plan to add a Mobile Service Tower (MST) to LC-39A that will   
   allow for vertical integration of payloads after the launcher (Falcon 9   
   or Falcon Heavy) has been raised to the vertical. The MST will be on   
   rails and moved into position over the LV and the strong-back and   
   covered to allow protection for crews completing the vertical   
   integration of the payload. Apparently some future payloads may be   
   sensitive to being erected from the horizontal to the vertical. The MST   
   will then be retracted back away from the pad for launching.   
      
   This will make LC-39A look more conventional as compared to other launch   
   facilities in the past. Notably Titan and Atlas. Good ideas are hard to   
   suppress. Or the more things change, the more they stay the same! :)
