It relates vehicle systems oper-ATION DURING FINAL COUNTDOWN PREPARATIONS THROUGH LIFT-OFF, AND INCLUDES THE ENTIRE FLIGHT PROGRAM TO SATELLITE SEPARATION IN ORBIT. On the basis of information from the diagram, a brief system analysis of the vehicle is performed. The results are presented graphically and include Vehicle state, state-transition breakdown Vehicle component makeup Launch program events Flight profile of cumulative events and vehicle components remaining Condensed sequence diagram and Vehicle in-flight sequencing flight-test results. A narrative description of the vehicle launch program is included by way of a verbal interpretation of the master sequence diagram. Author
