RUNAWAY
To Bowman, the first intimation of trouble was a quiet voice saying over the open radio circuit. "Dave-I'm having control problems." Whitehead sounded slightly annoyed, but not in the least alarmed.
Before Bowman could answer, he saw the pod emerge from the shadow of the ship, only twenty feet beneath the main observation window. It was under full power, heading roughly along the line of Discovery's orbit.
"What's the trouble?" he called. For a few seconds there was no answer, and the pod was already a hundred feet away before Whitehead replied.
"Throttle jammed at full thrust," he said, quite calmly "I'm building up a little distance before I try anything."
That made sense, a runaway pod needed plenty of space to maneuver. And there was still no cause for real worry; Bowman was quite sure that Whitehead would soon fix the trouble, as he had always done in the past.
The seconds ticked slowly by; the pod was still gaining speed-and now it was so far away that it was barely recognizable. Though Whitehead would have no difficulty in homing on the ship from a distance of many miles, he had better not leave matters until too late for his main drive would empty the propellant tanks in a very few minutes.
The pod was now a tiny spot, its distance impossible to judge by the eye. Bowman locked the navigation radar on it, and was surprised to find that it was still only two miles away. But, far more serious, it was already traveling at a hundred and ninety miles an hour.
"Peter!" cried Bowman. "What the hell's happening? Can't you fix it?"
For the first time, there was a note of alarm in Whitehead's voice.
"Controls won't respond," he said. "I'm pulling the main fuse to cut off power. Call you back."
A second later, his radio went dead. While waiting, Bowman searched for the pod with a telescope, and found it quickly enough. With a sinking heart, he saw the little cloud of mist flaring from the rocket nozzle, and knew that the capsule was still accelerating.
Whitehead was back on the air almost at once.
"No use," he said abruptly. "Trying to turn with auxiliaries."
It was a tricky maneuver, but the obvious next step. Even if he could not turn off the main drive, he should be able to spin the pod around so that he reversed the direction in which it was building up its uncontrollable velocity. Then the runaway would eventually be brought to rest, and presently it would start coming back again.
Tense and pale, with a dreadful feeling of helplessness, Bowman stared through the telescope. In its field of view, the pod seemed only a few feet away, and he could see every detail of its construction. Then, to his enormous relief, little spurts appeared from the attitude-control nozzles, and the capsule began to turn slowly on its axis.
The treacherous main drive swung out of sight, still firing, next he had a broadside view-then he was looking straight into the bay window at the seated figure of his friend. He could have seen Whitehead's expression, if it had not been for the glare of reflected sunlight on the transparent panels.
"You've done it!" he cried. "Thank God!"
The capsule was still racing away at over two hundred miles an hour-but at least it was now losing speed, no longer gaining it, as its jet acted as a brake.
"Looks like it," said Whitehead, his voice showing his immense relief. "I knew Betty wouldn't let me down, if I treated her properly."
Though it seemed ages, it was less than a minute before Bowman could tell, even without the aid of radar, that Whitehead was on the way back. Presently the capsule began to grow in the field of the telescope-slowly at first-then rapidly-then too rapidly.
"Still can't cut the damn thing," said Whitehead. "Hate to waste all this fuel, but I'll just have to swing to and fro until I run out of gas."
It seemed to Bowman that the capsule was now heading straight toward the ship; they were out of the frying pan and into the fire. The risk of losing Whitehead had …
