Strong turned to face the silent cadets.
"Sam Jones was pretty much like you, Astro. Not as big, but with the same love for that power deck. He could always squeeze a few extra pounds of thrust out of those rockets. What he knew about astrogation and control, you could stick on the head of a pin. On long flights he wouldn't even come up to the control deck. He just sat in the power hole singing loud corny songs about the Arkansas mountains to those atomic motors. He was a real power-deck man. But he was a unit man first! The only reason I'm here to tell you about it is because he never forgot the unit. He died saving Addy and myself."
The room was still. Down the long hall, the lively chatter of other cadets could be heard as they showered and prepared for dinner. In the distance, the rumble of the slidewalks and test firing of rockets at the spaceport was dim, subdued, powerful.
"The unit is the backbone of the Academy," continued Strong. "It was set up to develop three men to handle a Solar Guard rocket cruiser. Three men who could be taught to think, feel and act as one intelligent brain. Three men who would respect each other and who could depend on each other. Tomorrow you begin your real education. You will be supervised and instructed personally.
"Many men have contributed to the knowledge that will be placed in front of you—brave, intelligent men, who blasted through the atmosphere with a piece of metal under them for a spaceship and a fire in their tail for rockets. But everything they accomplished goes to waste if the unit can't become a single personality. It must be a single personality, or it doesn't exist. The unit is the ultimate of hundreds of years of research and progress. But you have to fight to create it and keep it living. Either you want it, or you get out of the Academy!"
Captain Strong turned away momentarily and Tom and Astro looked at Roger significantly.
"Stand to!"
The three boys snapped to attention as the wide-shouldered captain addressed them again.
"Tomorrow you begin to learn how to think as a single brain. To act with combined intelligence as one person. You either make up your minds to start tomorrow or you report to Commander Walters and resign. There isn't any room here for individuals."
He stepped to the door and paused.
