"Take her up," said Sergeant Madden.
The squad ship fell toward the sky. Sergeant Madden said satisfiedly:
"That went off pretty good. From now on it's just routine."
There was a bubble in emptiness. It was a large bubble, as such things go. It was nearly a thousand feet in diameter, and it was made of multipoly plastic which is nearly as anomalous as its name. The bubble contained almost an ounce of helium. It had a three-inch small box at one point on its surface. It floated some twenty-five million miles from the Huk planet, and five million miles from another bubble which was its identical twin. It could reflect detector-pulses. In so doing it impersonated a giant fighting ship.
Something like an hour after the squad ship rose from Sirene IV, a detonator-cap exploded in the three-inch box. It tore the box to atoms and initiated a wave of disintegration in the plastic of the bubble. The helium bubble-content escaped and was lost. The plastic itself turned to gas and disappeared.
The bubble had been capable of exactly two actions. It could reflect detector-pulses. In doing so, it had impersonated a giant fighting ship, member of an irresistible fleet. It could also destroy itself. In so doing, it impersonated a giant fighting ship—one of a fleet—going into overdrive.
In rapid succession, all the bubbles which were members of a non-existent fighting fleet winked out of existence about Sirene IV. There were a great many of them, and no trace of any remained.
The last was long gone when a small salvage ship descended to the Huk home planet. A heavily accented voice talked it down.
The salvage ship landed amid evidences of cordiality. The Huks were extremely co-operative. They even supplied materials for the repair job on the Cerberus, including landing rockets to be used in case of need. But they weren't needed for take-off. The Cerberus had been landed at a Huk spaceport, which obligingly lifted it out to space again when its drive had been replaced.
