Rob heaved a deep sigh. He knew at last what was in store for him, but this knowledge held little satisfaction. The things spoken between him and the general in the few minutes they had been together had been staggering in concept. It was hard for him to realize that he was part of such a colossal scheme. It was more like a dream. “Naturally you and your crew will run considerable risk,” General Forester said. “I’ve been told to give you the refusal of the job if you feel that you cannot go through with it. But I pray that you’ll give it considerable thought before you turn it down. I don’t know of a better man in the service to trust with the future of humanity.” _The future of humanity._ Dependent upon him, an insignificant one of several billions who populated Earth! The idea nearly bowled Rob over. Yet he found himself agreeing to take on the task. He spoke quickly lest he wait too long and find himself withdrawing. General Forester led him out of the building through a connecting tunnel to a plastic-domed hangar. Here Rob saw a little hundred-foot X-500 Cetus fighter rocket crawling with a ground crew that was obviously readying it for flight. It was quickly evident to Rob that the Cetus was a specially adapted make, for it was unusually deep-bodied. “This is your ship,” the general explained. “It’s a model that was built especially to carry the C-bomb. There’s one room for a crew of six. The rest of the bulk is for shielding against radiation from the bomb.” Rob could readily appreciate this latter fact, knowing that cosmic-ray energy was many times more powerful than nuclear fission. “Is the crew on Luna now, sir?” Rob asked. “They’ll arrive on the ferry from the space station later today,” the other replied. “Let’s go back.” As they retraced their way through the tunnel, the general filled in more facts. “We had hoped to let the R-cloud approach closer before launching an attack, but the pressure of public suspicion makes it necessary to get on the job right away. You’ll carry the X-500 to Titan where you’ll pick up the bombs from our Command unit there and get your final instructions. After that, you’re on your own.” Six men battling the greatest pack of energy ever faced by mankind! It was almost like tempting fate, Rob thought; like facing a mechanized army with only a club for a weapon. But Rob had confidence in the scientists of this day and their devastating brain child, the cosmic ray bomb. Rob met his crew in the general’s office. He silently studied the young men, selected as the best in their field, who would be entrusted with the lives of three billion people.
