Atom Drive Part 4

He sat up suddenly. Deveet looked at him in surprise. Jonner's lips moved silently for a moment, then he got to his feet.

"Where can we use a radiophone?" he asked.

"One in my office," said Deveet, standing up.

"Let's go. Quick, before Phobos sets."

They turned in their rods, Deveet collecting the credits for his fish, and left the Recreation Center.

When they reached the Atom-Star Company's Martian office Jonner plugged in the radiophone and called the Phobos s.p.a.ce station. He got T'an.

"All of you get aboard," Jonner ordered. "Then have Qoqol call me."

He signed off and turned to Deveet. "Can we charter a plane to haul our Earthbound cargo out of Marsport?"

"A plane? I suppose so. Where do you want to haul it?"

"Charax is as good as any other place. But I need a fast plane."

"I think we can get it. Marscorp still controls all the airlines, but the Mars government keeps a pretty strict finger on their planetbound operations. They can't refuse a cargo haul without good reason."

"Just to play safe, have some friend of yours whom they don't know, charter the plane in his name. They won't know it's us till we start loading cargo."

"Right," said Deveet, picking up the telephone. "I know just the man."

Towmotors scuttled across the landing area at Marsport, shifting the cargo that had been destined for the _Radiant Hope_ from the helpless G-boat to a jet cargo-plane. Nearby, watching the operation, were Jonner and Deveet, with the Marsport agent of Mars Air Transport Company.

"We didn't know Atom-Star was the one chartering the plane until you ordered the G-boat cargo loaded on it," confessed the Mars-Air agent.

"I see you and Mr. Deveet are signed up to accompany the cargo. You'll have to rent suits for the trip. We have to play it safe, and there's always the possibility of a forced landing."

"There are a couple of s.p.a.cesuits aboard the G-boat that we want to take along," said Jonner casually. "We'll just wear those instead."

"Okay." The agent spread his hands and shrugged. "Everybody at Marsport knows about you bucking Marscorp, Captain. What you expect to gain by transferring your cargo to Charax is beyond me, but it's your business."

An hour later, the chartered airplane took off with a thunder of jets.

Aboard was the 20-ton cargo the _Radiant Hope_ was supposed to carry to Earth, plus some large parachutes. The Mars-Air pilot wore a light suit with plastic helmet designed for survival in the thin, cold Martian air.

Jonner and Deveet wore the bulkier s.p.a.cesuits.

Five minutes out of Marsport, Jonner thrust the muzzle of a heat-gun in the pilot's back.

"Set it on automatic, strap on your parachute and bail out," he ordered.

"We're taking over."

The pilot had no choice. He went through the plane's airlock and jumped, helped by a hearty boost from Jonner. His parachute blossomed out as he drifted down toward the green Syrtis Major Lowland. Jonner didn't worry about him. He knew the pilot's helmet radio would reach Marsport and a helicopter would rescue him shortly.

"I don't know what you're trying to do, Jonner," said Deveet apprehensively over his s.p.a.cehelmet radio. "But whatever it is, you'd better do it fast. They'll have every plane on Mars looking for us in half an hour."

"Let 'em look, and keep quiet a while," retorted Jonner. "I've got some figuring to do."

He put the plane on automatic, took off the s.p.a.cesuit handhooks and scribbled figures on a sc.r.a.p of paper. He tuned in the plane's radio and called Qoqol on Phobos. They talked to each other briefly in Martian.

The darker green line of a ca.n.a.l crossed the green lowland below them.

"Good, there's Drosinas," muttered Jonner. "Let's see, time 1424 hours, speed 660 miles an hour...."

Jonner boosted the jets a bit and watched the terrain.

"By Saturn, I almost overran it!" he exclaimed. "Deveet, smash out those ports."

"Break out the ports?" repeated Deveet. "That'll depressurize the cabin!"

"That's right. So you'd better be sure your s.p.a.cesuit's secure."

Obviously puzzled, Deveet strode up and down the cabin, knocking out its six windows with the handhooks of his s.p.a.cesuit. Jonner maneuvered the plane gently, and set it on automatic. He got out of the pilot's seat and strode to the right front port.

Reaching through the broken window, he pulled in a section of cable that was trailing alongside. While the baffled Deveet watched, he reeled it in until he brought up the end of it, to which was attached a fish-shaped finned metal missile.

Jonner carried the cable end and the attached missile across the cabin and tossed it out the broken front port on the other side, swinging it so that the 700-mile-an-hour slipstream snapped it back in through the rearmost port like a bullet.

"Pick it up and pa.s.s it out the right rear port," he commanded. "We'll have to pa.s.s it to each other from port to port. The slipstream won't let us swing it forward and through."

In a few moments, the two of them had worked the missile and the cable end to the right front port and in through it. Originating above the plane, it now made a loop through the four open ports. Jonner untied the missile and tied the end to the portion which came into the cabin, making a bowline knot of the loop. Deveet picked up the missile from the floor, where Jonner had thrown it.

"Looks like a spent rocket sh.e.l.l," he commented.

"It's a signal rocket," said Jonner. "The flare trigger was disconnected."

He picked up the microphone and called the _Radiant Hope_ on Phobos.

"We've hooked our fish, Qoqol," he told the Martian, and laid the mike aside.

"What does that mean?" asked Deveet.

"Means we'd better strap in," said Jonner, suiting the action to the words. "You're in for a short trip to Phobos, Deveet."

Jonner pulled back slowly on the elevator control, and the plane began a shallow climb. At 700 miles an hour, it began to attain a height at which its broad wings--broader than those of any terrestrial plane--would not support it.

"I'm trying to decide," said Deveet with forced calm, "whether you've flipped your helmet."

"Nope," answered Jonner. "Trolling for those fish in Mars City gave me the idea. The rest was no more than an astrogation problem, like any rendezvous with a ship in a fixed orbit, which Qoqol could figure.

Remember that 6,000-mile television cable the ship's hauling? Qoqol just shot the end of it down to Mars' surface by signal rocket, we hooked on and now he'll haul us up to Phobos. He's got the ship's engine hooked onto the cable winch."

The jets coughed and stopped. The plane was out of fuel. It was on momentum--to be drawn by the cable, or to snap it and fall.

"Impossible!" cried Deveet in alarm. "Phobos' orbital speed is more than a mile a second! No cable can take the sudden difference in that and the speed we're traveling. When the slack is gone, it'll break!"
