Less than an hour and a half later, the Cetus X-500 was ready to go. General Carmichael replaced the charts given Rob by General Forester with ones carrying figures for the accelerated moment of departure.

Rob considered Bruce Olney a capable fill-in for the valiant Mort Haines, if looks were any criterion. He was a slender, straw blond, with intelligent eyes. He wore a miniature good-luck horse-shoe charm around his neck.

A report from the infirmary showed that Mort Haines was still in serious condition. Rob saw Clay Gerard wince as he heard the news. Clay had been an exceedingly quiet individual since the accident to the mechanic, a different person entirely. His blatant self-confidence had been whittled down strikingly to a brooding reserve.

When the crew of the X-500 was already in the ship and about to blast off, General Carmichael spoke his final disturbing speech over their radio, “I’ve just had another report from General Forester. The people are mobbing the White House demanding to know what it is that threatens their lives. The President doesn’t believe he can hold them off much longer.” The general’s tone became grimmer and more emotional as he concluded. “Operation Big Boy has got to be a success, Allison. There’s no two ways about it. I want the next message you send to give the good news that we will immediately broadcast throughout the system. Good luck and God be with you.”

The six of them stared at one another soberly as the final words were spoken. The full enormity of their duty seemed to have struck them just now for the first time. Rob choked down the lump that pressed up into his throat. He took a full breath, readying himself, then gave his first command.

“Blast-off couches,” he spoke quietly. “Prepare for launching.”

When the roaring thunder of the blast-off was behind them and the rocket ship was grasping for the stars, Clay unbuckled his straps and turned to Rob.

“I don’t believe Dulcie spread that report about our project, lieutenant,” he said. “She wouldn’t lose her head. Not her. She’s the calmest one in the family. Besides, she’s a—a—”

“A Gerard?” Rob supplied, smiling faintly.

Clay flushed. “I guess I haven’t really changed, have I?” he said bleakly.
