"Tom isn't in a space suit. If we open the hatch it would kill him. We've got to tow him back to the Polaris and get his boat inside the air lock before we can open the hatch!"
Without a word, Astro nodded, ducked inside his ship, and climbed out again with a length of rope. Working quickly, he tied one end securely to the bow of Tom's jet boat and made the other end fast to the stern of his. Then returning to his cockpit, he sent the jet boat hurtling back toward the Polaris.
But he was still faced with the problem of getting Tom's jet boat inside the air lock. It was still under acceleration and there was no way to get inside to stop its jet motors. Astro called to Strong and explained the situation to him.
"Looks like the only thing we can do, sir, is keep going until it runs out of fuel."
"That might take too long, Astro," replied Strong. "No telling how much oxygen Tom has left."
"There's nothing else we can do, sir," replied Astro. "We can't brake her to land inside the Polaris and we can't open the hatch to turn off the motor. We'll have to take a chance on Tom lasting until it runs out of fuel!"
Inside the roaring craft, Tom suddenly opened his eyes. He began to cough. There was a roaring in his ears. The stars overhead swam dizzily. And then, as though through a billowing mist, he saw the jet boat ahead of him and the rope tied to his ship. He realized he had been rescued. He tried to signal them. He had to let them know he needed oxygen. He tried to reach the communicator near the control panel but could not lift his arm. He fell back to the deck gasping for air; his lungs screaming for oxygen. Something, thought Tom through the haze that fogged his brain, something to signal them. Then, with the last of his strength, he raised up on one elbow and reached for the acceleration lever. His fingers trembled a few inches away from their goal. His face began to turn violent red. He strained a little more. The lever was an inch away. Finally, with the very last ounce of his strength, he touched the lever and pulled it back by the weight of his falling body.
Even before the black cloud swept over him, Tom could hear the jets become silent. He had signaled them. He had stopped the jet boat. They would know, now, how to save him.
