"Sure could." Carson didn't look very happy as he found the schematic he wanted and glared silently at it for a moment. "Yeah. All the arm segment lines run separately all the way to the reservoir, it looks like, so that if one gives you've still got all the rest. They all run along the starboard side of the bay, right where the shuttle hit. Ten'll get you a hundred that's the trouble."

"Rick? How about it?" Greenburg called.

"Probably." Henson sounded disgusted. "I think the sensors are located in that same general area. You could probably track the line back visually and confirm it's broken."

"For the moment don't bother; its not worth the effort," Betsy's voice came in for the first time in many minutes. "Mr. Carson, can it be fixed or will we have to replace the whole arm?"

"I don't know. Frankly, I'm not sure either one can be done outside a hangar. Leastwise, not by me."

"I see." There was a pause—an ominously long pause, to Greenburg's way of thinking. "I'd like you to look at the arm, anyway, if you would, and see how much work replacing it would take. Aaron, would you come to the flight deck, please? We need to have a consultation."

"Sure, Bets." He made the words sound as casual as possible, even as his stomach curled into a little knot inside him. Whatever she wanted to discuss, it was something she didn't want the whole intercom net to hear... and that could only be bad news.

Moving as quickly as he dared, he headed back under the access panel and, kicking in his harness's motor, began to climb the wall.

It was, to the best of Betsy's knowledge, the first time the closed intercom system had ever been used aboard a Skyport, and she found her finger hesitating slightly as it pressed the button that would cut Seven's flight deck off from everyone except Carl Young on Four. But she both understood and agreed with the Skyport captain's insistence that this discussion be held privately. "All set here, Carl," she said into the grille.

"All right," the other's voice came back. "I'm sure I don't have to remind either of you what time it's getting to be."

"No, sir." The instrument panel clock directly in front of her read 10:02:35 EST, with the seconds ticking off like footsteps toward an unavoidable crossroads. "At just about fourteen twenty-five the shuttle runs out of fuel. If we're going to reach Mirage Lake before that happens, we're got to leave Dallas right now."

"Or in twenty minutes, if we wind up running right to the wire," Greenburg muttered from the copilot's chair. A shiver ran visibly through his body; but whether it was an aftereffect of the cold air down below or a reaction to the same horrible image that was intruding in Betsy's own mind's eye, she had no way of knowing.

"True; but we don't dare cut things that fine," Young said. "We don't know how long those two collar supports will hold under a full strain. How is the forward clamp?"

"It's shot," Greenburg said succinctly. "One of the segments has a broken hydraulic line, we think."

"Replaceable?"

Greenburg hesitated. "I don't know. The ground crew boss doesn't think so."

"What about the escape system for getting the passengers out?"

"Proceeding pretty well. If no new problems crop up I'd say they'll be ready with the thing in half an hour or so."

"Well, that's something, anyway. Betsy, what's the latest on Meredith's condition?"

Betsy took a deep breath. "It's not good, I'm afraid. The doctors say he's got at least a couple of broken ribs, a possible mild concussion, and slow but definite internal bleeding. They've got him laid out on cushions in the shuttle's aisle and have asked for some whole blood to be sent up. I've already radioed the ground; it'll be brought by the next shuttle up."

Greenburg gave a low whistle. "That doesn't sound good at all."

"It's not," she admitted. "There's also evidence that some of the blood may be getting into one of his lungs. Even if it's not, putting new blood into him's a temporary solution at best."

"How long before he has to get to a hospital?" Greenburg asked bluntly, his eyes boring into Betsy's.

"The doctors don't know. At the moment he's relatively stable. But if the bleeding increases—" She left the sentence unfinished.

"Four hours to L.A. at this speed. That's a long time between hospital facilities," Young mused, and Betsy felt a stab of envy at the control in his voice. Ultimately, it was really Carl, not her, who was supposed to be responsible for the safety of the Skyport and its passengers. What right did he have to be so calm when she was sweating buckets over this thing?

"Wait a second," Greenburg spoke up suddenly. "It doesn't have to be an all-or-nothing proposition. We could dock a shuttle in, say, Six and carry it with us to L.A. Then if Meredith got worse we could land him at any of the airports along the way."

"You're missing the point," Betsy snapped. The sharpness of her tone startled her almost as much as it did Greenburg, judging from his expression, and she felt a rush of shame at lashing out at him. "The problem," she said in a more subdued voice, "is that stuffing Meredith out that cockpit window and into a ski lift chair could kill him before we could get him down and to a hospital. The doctors didn't actually come out and say that they wouldn't allow it, but that was the impression I got. Given Rayburn's state of mind, I didn't want to press the point with him on the circuit."

"So what you're saying is that Meredith is stuck on the shuttle until it can be landed," Young said.

"Yeah, I guess that's basically what it boils down to," Betsy admitted. "Unless he takes a turn for the worse, in which case we'll probably have to go ahead and take the chance."

"Uh-huh." Young was silent for a moment. "All right, here's how things look from where I sit. I've been in contact with United, and they have absolutely insisted that getting the passengers out of the shuttle be our top priority—higher even than Meredith's life, if it should come to that. A second crew will be coming up with that shuttle you mentioned to help with the off-loading. The airline chiefs say they want—and I quote—'everyone safely aboard the Skyport with complimentary cocktails in their fists within an hour.' " For the first time, Young's voice strayed from the purely professional as a note of bitterness edged in. Somehow, it made Betsy feel a little better. "What happens to Meredith and the shuttle is apparently our problem until then, when presumably they'll be willing to lend more of a hand."

"So what do we do?" Greenburg asked after a short pause. "Get everything aboard that we'll need for the ski lift track and hightail it for L.A.?"

"We also need to fasten the shuttle more securely before we go," Betsy said. "Rayburn wants Meredith in a hospital immediately if not sooner, and if we try telling him he's going to have to wait another four hours he may try taking Meredith's safety into his own hands."

Greenburg frowned at her. "What do you mean?"

"Oh, that's right—you didn't hear that little gem of a conversation." In a half-dozen sentences Betsy summarized Rayburn's earlier outburst. Greenburg's eyes were wide with shocked disbelief by the time she finished. "Carl, we've got to get him out of that cockpit before he flips completely," he said, his left hand tracing restless patterns on the armrest.

"On what grounds? He hasn't actually tried to do anything dangerous. He could claim he was just blowing off steam."

"But—"

"No buts." The Skyport captain was firm. "We can't justify it—and besides, how do you think he'd react to an order like that?"

Greenburg clamped his lips together, and Betsy thought she saw some of the color go out of his face. "That's a little unfair," she said. "We don't know that he'd react irrationally." It felt strange to be defending Rayburn; quickly, she changed the subject. "Anyway, we're getting off the point. The immediate issue here is whether or not we head west in the next fifteen minutes. Carl, I guess this is your basic command decision."
