That was all he _did_ know for sure. None of the men had said who was going on the first trip to the moon. Nothing had been said on that subject at all, but Bobby knew Dad would go. He would have to. After all, Dad was the second biggest scientist at Buffalo Flats. Second only to Schleimmer himself and Professor Schleimmer was very old and certainly wouldn't make the trip. That left Dad. Dad would just have to go in order to run the rocket. There probably wasn't anybody else smart enough in the whole place. The idea of going himself had been born the previous day--when he found a larger grating in the floor near the rocket and realized if he was very careful he could climb out of the sewer and duck into the rocket when nobody was looking. Once inside he was pretty sure he'd find a place to hide until blast-off. All the men would probably be strapped in bunks but if he found a place he could wedge himself in he didn't think he'd get hurt. Then, halfway to the moon he would come out and find Dad and would he be surprised! At first, thinking about it, he'd been scared but after he realized how proud Dad and Mom would be, he made up his mind. Now, crouched beside the grating near the ship, he waited while two men--technicians in white overalls--walked by. One of them said, "Well, whatever happens, she'll make a big splash." "You said it. Hope the brains know what they're doing." That made Bobby mad. Who said Dad didn't know what he was doing? Dad was just about the smartest scientist in the world. After the two men left he waited a long time. He heard voices but no one came in sight. Taking a deep breath, he opened the grating and got out. It was only four steps to the open port of the rocket. There was a little ramp they'd used to roll things in and Bobby's feet touched it but lightly as he jumped into the ship. He found himself in some kind of a storeroom. It would be a good place to hide all right. It was full of aluminum barrels all the same size. He found a space between two rows and sat down and got his breath back. It was very quiet around him. Scary quiet. But he set his lips firmly. He was going to the moon with Dad. * * * * * John Kendall was a little late that night. He kissed his wife and said, "Well, did you see the big sky rocket?" "How could I miss it, darling? Your supper is in the oven." "I could use a Martini first." "Coming right up." While Myra fixed the drink John lay back in his easy chair and closed his eyes. "We'd hoped to stage a little ceremony at the launching but Washington said no." "The Russians?" "The Eastern Coalition. It was a race. That was why it had to be so secret. Washington said, light the fuse and fire the thing." "Is it still hush-hush?" "No. Not between us at least. We fired an explosion rocket at the moon. It will hit in about an hour and telescopes will show a big purple spot when our explosives go off and throw dye all over the place."
