From one side of the circular dais, Tom saw Major Connel enter the room. He snapped to attention and saluted smartly.

"Morning, Corbett," said Connel, returning Tom's salute. "Getting into the swing of the operation?"

"Yes, sir," said Tom. "I've handled about twenty approaches since Captain Stefens left me alone, and about fifty departures." Tom brought his fist up, with the thumb extended and wiped it across his chest in the traditional spaceman's signal that all was clear. "I didn't scratch one of 'em, sir," he said, smiling.

"Good enough," said Connel. "Keep it that way." He watched the monitor screen as the liner San Francisco settled into landing-port eleven.

When she was cradled and secure, he grunted his satisfaction and turned to leave. At the door he suddenly paused. "By the way, isn't Manning on radar watch?"

"Yes, sir," replied Tom.

"Well, it's one forty-eight. How about his standard check-in with traffic control?"

Tom stammered, "He—uh—he may be plotting some space junk, sir."

"He still must report, regardless of what he's doing!"

"I—uh—ah—yes, sir!" gulped Tom. Blast Roger anyway, he thought, forgetting the all-important quarter-hour check-in.
