RA & T platoon , with the aid of a wrecker, carefully lowers the rocket onto the launcher.    
Final checks are made in preparation for a launch; for others, their tasks are down and they sit on a hill waiting to see the show.    
ON THE WAY - a blinding flash and a terrific roar ensue as the rocket is fired.
