He sat down, amid cheers. He smiled sadly at Ron, and asked: "How about you, Ronnie? Can you operate a PF?"

"Of course," he answered, without thinking. He'd been using Personal Flyers since he was old enough to dream about flight. On his tenth birthday, his father had bought him one of the earliest models, a cumbersome machine then called a "platform". Since that day, he had become familiar with every man-made thing that flew, from the double-rotored PF's to the sixty-rocket space liners.

"Fine," Larkin said cheerfully. "Then maybe you'd like to play the game."

Ron Carver looked up sharply. Play the game....

"Sure, Mr. Larkin," he said, forcing his eagerness.

Half an hour later, they were assembled on the huge lawn outside of the main building of Roverwood Home for Boys. The long row of PF's, looking like chrome-plate pot-bellied stoves, gleamed in the morning sun. The boys began to run when they saw their Flyers, and Ron found his arm taken by the freckled youth who had entered his room.

"Hoy," he said. "Follow me. I'll pick you out a lively one!"

The redhead clambered inside a machine marked Seven, and Ronnie followed his instructions by choosing the vehicle marked Nine. They secured themselves inside, and tested the jet tube set in front of the Flyer. The boys took off from the ground in perfect unison, the redhead bellowing out an introduction over the sound of the wind roaring past their ears.

The PF's descended on a blast from Mr. Larkin's whistle, congregating in the center of the field. Teams were chosen, and Andy was picked as Captain of the Odds. A coin was tossed to decide the playing sequence, and they were ready.

Larkin released the first airball, and the two teams streamed up after it. Andy gunned the engine and reached the ball first. He sent it scooting thirty yards ahead of him with the blast of the airjet pipe, but a member of the Evens team was there to veer it off to the left. Another Evens man, a burly youth of fourteen, took command of it, neatly getting the airball in the sight of his airjet and cork-screwing it towards the goalpost. Ron had grown too old before the game of airball had become popular with the nation's youngsters, but he had seen enough action to have learned some tricks. He pointed his PF directly for the Even machine, and kept coming. The burly youth looked up, startled at the onslaught, and pulled his Flyer away. The fact that the PF's were magnetically collision-proof didn't matter; it was pure instinct. Ron captured the ball in his airjet pipe, and shouted for Andy to block his path towards the goal.
