"If Tom managed to get in there, or if he was in there when the ship exploded, maybe he has a chance."

"You're right, Astro," said Kit hopefully.

"But we can't open it out here," said Astro. "If Tom is inside, we have to take it down to Deimos. If we open it here, and he doesn't have a space suit on, he'd suffocate."

"He'd freeze solid before that," said Kit, not mentioning the possibility that Tom might very well be frozen already, since the ship's heating units had been torn away from the air lock.

Quickly Astro hailed the members of the emergency crews that had rocketed up from Deimos and told them of the possibility that Tom was inside the chamber. They all agreed, since they had failed to find the cadet anywhere.

Kit and Astro immediately took charge of getting the bulky boxlike chamber back to Deimos where it could be opened safely. Two of the jet boats were jockeyed into position on either side of the chamber and several lengths of cable were stretched between them, forming a cradle for the chamber. Since the jet boats were equipped with foldaway wings, which, when extended, would enable them to fly at slower speed through atmosphere, they hoped to make a glider landing at the Deimos spaceport.

Astro would not let anyone handle the boats but Kit and himself, and only by threat of physical violence was he able to keep the regular pilots out of the control chairs on the speedy little ships. He might suffer for it later when the officers reported his actions, but the big Venusian was beyond caring. If Tom was not safe inside the vacuum chamber, he felt there wasn't much use in being a cadet any longer. Fleetingly he thought of Roger, who didn't stand a chance of reaching Ganymede on a single solo hop from Earth in a ship the size of the Space Knight. The Polaris unit seemed doomed.

With Kit Barnard in one jet boat, Astro strapped himself into the control chair of the other, and intercoms on, they gently fed power into their ships. Coordinating perfectly in their maneuvers, they headed back to the spaceport with their strange cargo.
