This Is An Underground Center In Which The Raising, Fueling And Firing Of A Missile Is Performed. This Was A Training Exercise For Crews And Included All Of The Procedures Except Firing Of The Missile. Observers And Umpires Check And Score The Operation As The Count Down Nears Completion. Gathered As They Are About The Master Console As The Missile Comes Out Of The Silo, An Air Of Excitement, Intentness And At The Same Time Quiet Confidence Exists.
