<passage>:
Firebrand Dennis Brooke had one final chance to redeem himself by capturing Koerber whose ships were the scourge of the Void. But his Marla left an aching void that all the women of five planets could not fill, the loss of Space, was quite as deadly. For he had been grounded. True, Koerber's escape from the I.S.P. net had not quite been his fault but had he not been enjoying the joys of a voluptuous Jovian side. Tiny on the viso-screen, the fatal spots must have been huge in "When do I leave, Commander!" Dennis Brooke's voice was like a javelin as a wild goose chase, a speck was limned in the lighted surface of the viso-screen in the control room. Instantly the I.S.P. cruiser came to Presently they were within reaching distance, and Captain Brooke commanded through the teleradio from the control room: "Prepare to board!" Every member of the crew wanted to be among the boarding party, for missing. No survivors. No indication that the repulsion fields were out of order. And finally, those Genton shells could only have been fired by Koerber!" He tried to maintain a calm exterior, but inwardly he seethed in a cold fury more deadly than any he had ever experienced. Somehow he had expected to find at least one compartment unharmed, where life might have endured, but now, all hope was gone. Only a great resolve to deal with Koerber once and for all remained to him. airlocks and removed the space suits. "Captain Brooke ... Captain, recordings are showing on the new 'Jet Analyzers' must be the trail of some spacer. Can't be far!" He was prayed that it were Koerber. It had to be! No interplanetary passenger spacer could possibly be out here at the intersection of angles Kp 39 degrees, 12 minutes, Fp 67 degrees of Ceres elliptic plane. None but a pirate crew with swift battle cruisers could dare! This was the uncharted orbits. Dennis, Tom Jeffery and Scotty Byrnes raced to the control room, anathema. There could be no doubt now! The "Jet Analyzer" recorded powerful disturbance, atomic—could be nothing else. Instantly Captain Brooke was at the inter-communication speaker: "Crew, battle stations! Engine room, full speed!" Scotty Byrnes was already dashing to the engine room, where his beloved motors purred with an ascending hum. Aboard the I.S.P. Cruiser each member of the crew raced to his assigned task without delay. Action unmistakably for what it was—a pirate craft, it showed by its sudden maneuver that it had detected the I.S.P. cruiser. For it had described a parabola in space and headed for the dangerous asteroid belt. As if asteroids, it plunged directly into the asteroid drift, hoping to lose the I.S.P. cruiser with such a maneuver. Ordinarily, it would have succeeded, no I.S.P. patrol ship would have dared to venture into such a trap without specific orders. But to Dennis Brooke, directing the chase from the control room, even certain death was welcome, if only he could take Koerber with him. Weaving through the deadly belt for several hours, Dennis saw his quarry slow down. Instantly he seized the chance and ordered a salvo from starboard. Koerber's powerful spacer reeled, dived and came up spewing Genton-shells. The battle was on at last. From the banked atom-cannon of the I.S.P. Cruiser, a deadly curtain of atomic fire blazed at the pirate craft. A ragged rent back toward midship showed on Koerber's Cruiser which trembled as if it had been mortally wounded. Then Dennis maneuvered his cruiser into a power dive as a rain of Genton-shells swept the space lane above him, but as the detonating impact. It was then that Dennis Brooke saw the immense dark shadow looming immediately behind Koerber's ship. He saw the pirate cruiser zoom desperately in an effort to break the gravity trap of the looming mass, but too late. It struggled like a fly caught in a spider-web to no avail. It was then that Koerber played his last card. Sensing he was doomed, he tried to draw the I.S.P. Cruiser down with him. A powerful magnetic beam lashed out to spear the I.S.P. Cruiser. With a wrenching turn that almost threw them out of control, Dennis maneuvered to avoid the beam. Again Koerber's beam lashed out, as he maneuver avoided it. "George Randall!" He shouted desperately into the speaker. "Cut all jets in the rocket room! Hurry, man!" He banked again and then zoomed out of the increasing gravity trap. "Randall! I've got to use the magnetic repulsion plates.... Cut all the jets!" But there was no response. Randall's screen remained blank. Then Koerber's lashing magnetic beam touched and the I.S.P. ship was caught, forced to follow the pirate ship's plunge like the weight at the end of a whiplash. Koerber's gunners sent one parting shot, an atom-blast that shook the trapped cruiser like a leaf. Beneath them, growing larger by the second, a small world rushed up to And then began another type of battle. Hearing the Captain's orders to Randall, and noting that no result had been obtained, Scotty Byrnes himself cut the jets. The Magnetic Repulsion Plates went into action, too late to save them from being drawn, but at least they could prevent a crash. Far in the distance they could see Koerber's ship preceding them in a free fall, then the Planetoid was rushing up to engulf them. III The atmosphere was somewhat tenuous, but it was breathable, provided a man didn't exert himself. To the silent crew of the I.S.P. Cruiser, the strange world to which Koerber's magnetic Beam had drawn them, was anything but reassuring. Towering crags jutted raggedly against ordinarily gentle voice like a lash. "But, you may as well know it," Scotty replied quietly. "That parting shot of Koerber's severed our main rocket feed. I had to use the emergency tank to make it down here!" "I think we got Koerber, though," he said at last. "While Tom was doing a job of navigation, I had one last glimpse of him coming down fast and out of control somewhere behind those crags over there!" "To hell with Koerber!" Tom Jeffery exploded. "You mean we're stuck in this hellish rock-pile?" "Easy, Tom!" Captain Brooke's tones were like ice. On his pale, "Better break out those repair plates," Dennis said to Scotty. "Tom, you get the welders ready. I've got a few entries to make in the log book, and then we'll decide on a party to explore the terrain and try to find out what happened to Koerber's ship. I must know," he said in a low voice, but with such passion that the others were startled. A figure appeared in the slanting doorway of the ship in time to hear

<question>:
Why did George Randall's failure to follow orders result in Dennis' ship being pulled down to the planetoid?

<options>:
A The jets needed to be turned on and off at specific times to use the planetoid as a slingshot to catch Koerber. Since they got power at the wrong time, they were propelled to the planetoid's surface.
B Since George Randall didn't follow the order to cut jets, that meant another crewman had to do it, which meant that crewman couldn't do his own job of positioning the magnetic repulsion plates.
C With the jets still on, the magnetic repulsion plates could not be activated, resulting in them being tractored in by Koerber's ship.
D With the jets still on, their ship could not "run silent" and avoid detection by Koerber's ship.
