   They're testing the first copy of the actual flight hardware and don't   
   want to break it.  So, if anything goes wrong, they stop the test to   
   protect the flight hardware from possible damage.   
      
   This is literally a paperwork heavy program.  If it were hardware rich,   
   like NASA was doing in the early 1960s, they'd have had all of this   
   testing done years ago on a "pathfinder" stage.
