"As soon as you get outside the hatch here," said Tom, "turn back this way. Keep your face up against the bulkhead until you get to the top.
Right above you is the ladder. You can grab it to pull yourself up."

"O.K.," said Astro and took the length of hose and put it in his mouth.
Then, taking a piece of waste cotton, he stopped up his nose and tested the hose.
"Can you breathe O.K.?" asked Tom.
Astro signaled that he could and stepped through the hatch. He turned, and facing backward, began clawing his way upward.
"Keep that hose clear, Roger!" ordered Tom. "There's about five feet of sand that he has to dig through and if any of it gets into the hose--well--"
"Don't worry, Tom," interrupted Roger. "I've got the end of the hose right next to the oxygen bottle. He's getting pure stuff!"
Soon the big cadet was lost to view. Only the slow movement of the hose and rope indicated that Astro was all right. Finally the hose and rope stopped moving.
Tom and Roger looked at each other, worried.
"You think something might be wrong?" asked Tom.
"I don't know--" Roger caught himself. "Say, look--the rope! It's jerking--Astro's signaling!"

"He made it!" cried Tom.
"I wonder if--" Roger suddenly picked up the end of the hose and spoke into it. "Astro? Hey, Astro, can you hear me?"
"Sure I can." Astro's voice came back through the hose. "Don't shout so loud! I'm not on Earth, you know. I'm just ten feet above you!"
Roger and Tom clapped each other on the shoulders in glee.
"All set down there?" called Astro, through the hose.
"O.K." replied Tom.
"Listen," said Astro, "when you get outside the hatch, you'll find a pipe running along the bulkhead right over your head. Grab that and pull yourself up. Tie the rope around your shoulder, but leave enough of it so the next guy can come up. We don't have any way of getting it back down there!" he warned. "Who's coming up first?"
Tom looked at Roger.
"You're stronger, Tom," said Roger. "You go up now and then you can give Astro a hand pulling me through."
"All right," agreed Tom. He began pulling the hose back through the sand. He took the end, cleared it out with a few blasts from the oxygen bottle and put it in his mouth. Then, after Roger had helped him tie the rope around his shoulders, he stuffed his nose with the waste cotton. He stepped to the opening. Roger gave three quick jerks on the rope and Astro started hauling in.
With Astro's help, Tom was soon free and clear, standing beside Astro on the jet-boat deck.
"Phoooeeeey!" said Tom, spitting out the sand that had filtered into his mouth. "I never want to do that again!" He dusted himself off and flashed his emergency light around the deck. "Look at that!" he said in amazement. "If we'd kept on digging, we'd have been trapped down there for--" he paused and looked at Astro who was grinning--"a long, long time!" He held the light on the sand that was flowing out of the open hatch of the passenger lounge.
"Come on," urged Astro. "Let's get Roger out of there!"
They called to Roger through the hose and told him to bring two more emergency lights and the remainder of the Martian water. Three minutes later the _Polaris_ unit was together again.
Standing on the deck beside his two unit-mates, Roger brushed himself off and smiled. "Well," he said, "looks like we made it!"
"Yeah," said Tom, "but take a look at this!" He walked across the jet-boat deck to the nearest window port. What should have been a clear view of the desert was a mass of solidly packed sand.
"Oh, no!" cried Roger. "Don't tell me we have to go through that again?"
"I don't think it'll be so bad this time," said Astro.
"Why not?" asked Tom.
"The sand is banked the heaviest on the port side of the ship. And the window ports on the starboard side of the control deck were pretty high off the ground."
"Well, let's not just stand here and talk about it," said Roger. "Let's take a look!" He turned and walked through the jet-boat deck.
Tom and Astro followed the blond cadet through the darkened passages of the dead ship, and after digging a small pile of sand away from the control-deck hatch, found themselves once more amid the jumble of the wrecked instruments.
For the first time in three days, the boys saw sunlight streaking through the crystal port.
"I told you," cried Astro triumphantly.
"But there still isn't any way out of this place!" said Roger. "We can't break that port. It's six inches thick!"
"Find me a wrench," said Astro. "I can take the whole window port apart from inside. How do you think they replace these things when they get cracked?"
Hurriedly searching through the rubble, Tom finally produced a wrench and handed it to Astro. In a half hour Astro had taken the whole section down and had pushed the crystal outward. The air of the desert rushed into the control room in a hot blast.
"Whew!" cried Roger. "It must be at least a hundred and twenty-five degrees out there!"
"Come on. Let's take a look," said Tom. "And keep your fingers crossed!"
"Why?" asked Roger.
"That we can dig enough of the sand away from the ship to make it recognizable from the air."
Following Tom's lead, Roger and Astro climbed through the open port and out onto the sand.
"Well, blast my jets!" said Astro. "You can't even tell there was a storm."
"You can't if you don't look at the ship," said Tom bitterly. "That was the only thing around here of any size that would offer resistance to the sand and make it pile up. And, spaceman, look at that pile!"
Astro and Roger turned to look at the spaceship. Instead of seeing the ship, they saw a small mountain of sand, well over a hundred feet high.
They walked around it and soon discovered that the window port in the control deck had been the only possible way out.
"Call it what you want," said Roger, "but I think it's just plain dumb luck that we were able to get out!" He eyed the mound of sand. Unless one knew there was a spaceship beneath it, it would have been impossible to distinguish it from the rest of the desert.
