Merlin, alias Lefty Camillion, and his electronics wizard were fitting a rocket into a loop on a plastic strap that dangled from the balloon. Rick couldn't see it clearly, but thought it was a replica of the one he had recovered.

There was sound from the truck containing the dish antenna. Rick pulled his mask away to hear a little better and heard a loudspeaker, rebroadcasting something.

"... reports no aircraft within range limits. We are now at thirty-one minutes and counting. On my mark the time will be zero minus thirty exactly."

There was only the crackle of the loudspeaker. The set was tuned in on the Wallops Island command frequency, Rick realized. That was how Camillion and company knew when to release the balloon, and when to trigger the rocket!

Camillion's bodyguard was manning the rope holding the balloon. It was attached to a ring on the truck. As Rick watched, the bodyguard let out more line and the balloon rose slightly, tugging at the rope, and moving toward Rick. The tail hung down almost to the ground, the rocket hanging at an angle at its end.

The loudspeaker voice said, "Stand by. Mark! Zero minus thirty."

The bodyguard reached up and cut the rope!

Rick saw the flying stingaree heading directly toward him, rising slowly, caught by the ground wind. He brought his spear gun into position and rose to his full height, snapping off the safety catch. Oblivious to the yells from the lawn, he aimed and fired. With a sharp hiss, the spear flashed through the air—into the balloon and right through it!

The balloon didn't even falter. It would take time to lose sufficient gas to bring it down. The wind swept it right toward Rick, still rising. As it passed over him, the dangling rocket would be almost within reach.

Rick didn't hesitate. He saw the track of the balloon curving, as the wind shifted direction downstream over the water. He threw himself to one side and forward, dropping the spear gun, one hand outstretched. The rocket slapped into his palm and his fingers closed around it. The jerk pulled him forward and he grabbed with his other hand, missed, and grabbed again. This time he caught the rocket, and both hands gripped tight.
