"I don"t know, but she said he does something with computers for them."
Betsy turned around to look at Lewis, who shrugged and nodded a.s.sent. "Close enough," she told the Skyport captain. "Can you get him up here right away?"
"I"ll go get him myself," Marinos volunteered. "I"ll be there in a couple of minutes."
"All right. Let"s get back to the shuttle itself, then," Young said. "Betsy, you said the collar supports were broken. Any idea how that happened?"
"I can only speculate that the collar had established a partial grip before the shuttle did its sideways veer into the bay wall."
"In that case, the crash may have left both the outer shuttle door and the exit tunnel intact. Any chance of getting the two connected and getting the pa.s.sengers out of there?"
"I don"t know." Betsy peered at the screen, made a slight adjustment in the contrast. "They"re out of line, for sure. I don"t know if the tunnel will stretch far enough to make up the difference."
"Even if it does, we"d need portable oxygen masks for all the pa.s.sengers," Henson pointed out from behind her. "They have to be using the shuttle"s air masks, and they can"t travel with those."
"That"s not going to be a problem," Young said. "I"ve already invoked emergency regulations; we"re bringing her down to fifteen thousand feet."
"Well, there"s nothing more I can tell from here." Betsy shook her head. "Someone"s going to have to go down and take a look. Who aboard this bird knows the most about docking bay equipment?"
There was a pause. "I don"t know whether I know the most," Greenburg spoke up diffidently at Betsy"s right, "but I"ve seen the blueprints, and I worked summers as a mechanic"s a.s.sistant for Boeing when I was in college."
"Anyone able to top that?" Young asked. "No? All right, Greenburg, get going."
Betsy put her half-headset back on as Greenburg removed his and stood up. "A set of the relevant blueprints would be helpful," he said, looking back at Lewis.
"I"m having the computer print them," the other told him. "If you want to go down and get the oxygen gear together, I"ll come down and give you a hand."Greenburg glanced questioningly at Betsy. "Can you do without both of us that long?"
She hesitated, then nodded. "Sure. But make it a fast look-see. You"re not going down there to do any major repair work."
"Right," Greenburg started for the door. "Meet you by the port-aft cargo access hatch, Tom."
Lewis waved an acknowledgment, his eyes on the computer screen, as Greenburg exited. Betsy turned back to face forward, and as she did so Rayburn"s voice crackled in her ear. "Skyport, this is Rayburn.
The doctor says John"s alive!"
A small part of the tightness across Betsy"s chest seemed to disappear. "Thank G.o.d! Is the doctor still there? I want to speak with him."
"Just a second." There was a moment of silence punctuated by a.s.sorted clicks, and then a new voice came tentatively on the line. "h.e.l.lo? This is Dr. Emerson."
"Doctor, this is Wing Captain Elizabeth Kyser. What sort of shape is First Officer Meredith in?"
"Not a good one, I"m afraid," Emerson admitted. "He seems to have one or more cracked ribs and possibly a broken collarbone as well. The way the fuselage has bent inward and pinned him makes it hard to examine him. I could try pulling him out, but that might exacerbate any internal injuries, or even drive bits of gla.s.s into him from the broken windows. He"s unconscious, but his vital signs are stable, at least for the moment. I"m afraid I can"t tell you much more."
"Just knowing he"s alive is good news enough," Betsy a.s.sured him. She thought for a moment. "What if we could cut the whole chair loose? Is there enough room behind him to move the chair back and get him out that way?"
"Uh... I think so, yes. But I don"t know what we would do after that. I heard the flight attendant say the door was jammed."
Betsy frowned. Rayburn hadn"t mentioned that to her. "We might be able to force it open anyway and get it connected to the rest of the Skyport. Are the rest of the pa.s.sengers all right?"
"A few minor injuries, mostly bruises due to the safety belts. We"ve been very lucky."
So far. "Yeah. Thank you, Doctor. Please let us know immediately if there"s any change."
"Got the prints, Betsy," Lewis called as she turned off the mike. "I"m heading down."
He was gone before she could do more than nod a.s.sent, leaving her and Henson alone. For some reason the empty seats bothered her, and she briefly considered calling in some of Seven"s off-duty crewmen.
But as long as they were stuck in this virtual holding pattern, extra help on the flight deck would be pretty superfluous. Turning back to the instrument panel, she felt a wave of frustration wash over her. So many unanswered questions, most of them crucial to the safety of one or more groups of people aboard the Skyport*and she was temporarily at a loss to handle any of them. For the moment there was nothing she could do but try and line up the problems in some sort of logical order: if A is true then B must be done, and D cannot precede either B or C. But it was like juggling or playing chess in her head; there were just too many contingencies that had to be taken into account every step of the way.
Behind her the door opened, and she turned to see two men walk in. One she knew: Paul Marinos, captain of Wing Section Six. The other, a thirtyish young man in a three-piece suit, she"d never seen before. But she knew instantly who he was."Betsy," Marinos said, "this is Peter Whitney, of McDonnell Douglas."
Whitney had been daydreaming in his lounge chair, enjoying the unique Skyport atmosphere, when the violent b.u.mp jerked him back to full alertness. He shot a rapid glance around the room, half expecting to see the walls caving in around him. But everything looked normal. Up ahead, he could hear muttered curses from the dining room*prompted, no doubt, by spilled coffee and the like*while from the lounge itself came a heightened buzz of conversation. Whitney closed his ears to it all as best he could, straining instead to listen for some clue as to what had happened. An explosive misfire in one of the engines was his first gut-level guess; but the dull background rumble seemed unchanged. A hydraulic or fuel line that had broken with that much force might still be leaking audibly; again, he could hear nothing that sounded like that. Had there been that bogey of the "70s and early "80s, a mid-air collision?
But even small planes these days were supposed to be equipped with the Bendix-Honeywell transponder system*and how could any pilot fail to see the Skyport in the first place?
The minutes dragged by, and conversational levels gradually returned to normal as the other pa.s.sengers apparently decided that nothing serious had happened. Whitney suspected differently, and to him the loudspeaker"s silence was increasingly ominous. Something serious had happened, and the captain was either afraid to tell the pa.s.sengers what it was or the crew was just too d.a.m.n busy fighting the problem to talk. Neither possibility was a pleasant one.
A flash of royal blue caught the corner of his eye, and he turned to see a chunky man in a Skyport-crew jumpsuit step from the dining area into the lounge. The flight attendant who"d served Whitney"s breakfast was with him, and Whitney watched curiously as her gaze swept the room. It wasn"t until she pointed in his direction and the two started toward him that it occurred to Whitney that they might be looking for him. Even then uncertainty kept him in his seat until there was no doubt as to their target, and he had barely enough time to stand up before they reached him.
"Mr. Whitney?" the jumpsuited man asked. His expression was worried, his tone was politeness laminated on urgency. The girl looked worried, too.
Whitney nodded, noticing for the first time the gold wings-in-a-circle pins on his chest and shoulderboards. A wing captain, not just a random crew member. Whitney"s first hopeful thought, that this was somehow related to the tour he"d asked for, vanished like tax money in Washington.
"I"m Captain Paul Marinos," the other introduced himself. "We have a problem, Mr. Whitney, that we hope you can help us with. Is it true that you work with computer systems for McDonnell Douglas?"
Whitney nodded, feeling strangely tongue-tied, but finally getting his brain into gear. They were almost certainly not interested in just general computer knowledge; his nodded affirmative needed a qualifier added to it. "I know only a little about current Skyport programming, though," he told them. "I mostly work with second-generation research."
Marinos"s expression didn"t change, but his next words were almost a whisper. "What we need is a malfunction check on our shuttle approach and guidance equipment. Can you do that?"
The pieces clicked almost audibly into place in Whitney"s mind. It had been a crash, and one that all the Bendix-Honeywell collision-proofing in the world couldn"t prevent. "I don"t know, but I can try. Where do I find a terminal?"
"On Seven," was the cryptic response. "Come with me, please."Marinos led the way across the lounge and back into the dining room. A door in the right-hand wall brought them into one of the module"s food preparation and storage areas. The blonde flight attendant left them at that point; moving forward through the galley, Marinos and Whitney arrived at an elevator. One deck up was a somewhat cramped hallway lined with doors*crew quarters, Whitney a.s.sumed. In the opposite direction a heavy, positive-sealing door stood across their path. Marinos unlocked it and swung it open; and to Whitney"s mild surprise an identical door, hung the opposite way, faced them. The captain opened this one, too, and gestured Whitney through, sealing both doors again behind them.
"We"re on Wing Section Seven now," he told Whitney, leading the way down a hall that mirror-imaged the one they"d just left. "The wing captain here is Betsy Kyser. You"ll be working with her and her crew."
Beyond the hallway was a small lounge; pa.s.sing through it, they entered what appeared to be a ready-room sort of place with a half-dozen jumpsuited men and women listening intently to an intercom speaker; and finally, they reached the flight deck.
"We appreciate your coming up here," Captain Kyser said as Marinos concluded the introductions. "I hope you can help us."
"So do I," Whitney said. "Anything at all you can tell me about your malfunction? It might help my search."
"All we know is that it"s somewhere in the equipment or programming that guides shuttles into the docking bay." In a few terse sentences she told him what was known about the shuttle crash, including the craft"s current orientation in the bay. "My indicator said its approach velocity was too high, if that"s significant," she concluded. "But I don"t know if that was just my indicator or if the whole system was confused."
"The shuttle"s radar is independent of your equipment, though, isn"t it? Maybe the pilot can corroborate your readings."
"Maybe*but if he"d seen anything wrong he"d almost certainly have yelled. But I"ll ask him. First, though, I want to get you started. Paul, will you monitor the shuttle?"
Marinos, who had already quietly seated himself in the copilot"s seat, nodded and put on a headset.
Kyser removed her own and led Whitney to a console built snugly into the flight desk"s left rear corner.
Motioning him into the chair in front of it, she leaned over him and tapped at the keys. "Here"s the sign-on... access code... and program file." A series of names and numbers appeared on the screen.
"Any of those look familiar?"
"Quite a few, if the programming division"s keeping its nomenclature consistent." Whitney scanned the list, experimentally keyed in a number.
"That"s the standard equipment-check program," Kyser told him. "We"ve already run that one and come up dry."
"No errors? Then the problem probably isn"t in the computer system."
She shook her head. " "Probably" isn"t good enough. Aren"t there more complete test programs that can be run?"
"You"re talking about the full-blown diagnostic monsters that ground maintenance uses." Whitney hesitated, trying to remember what little he knew about such programs. "It seems to me that the program should be stored somewhere in your system, probably on one of the duplicate-copy disks. The catch is that the thing takes up almost all of your accessible memory s.p.a.ce, so anything that normally uses thats.p.a.ce will have to be temporarily shut down while it"s running."
Kyser looked over at the flight engineer. "Rick?"
"Jibes with what I"ve heard," he agreed. "Most of the programs that take a lot of s.p.a.ce are connected with navigation, radar monitoring, and mechanical flight systems and cargo deck stuff. We"re not using any of those at the moment, anyway, so that"s no problem. I can also switch a lot of the pa.s.senger-deck functions from automatic to manual control." He craned his neck to look at Whitney, sitting directly behind him. "Will that free up enough memory?"
"I don"t know*I don"t know how much room it"ll need. But there"s another problem, Captain.
Since it is such a big program, there"ll almost undoubtedly be safeguards to keep someone from accidentally loading it and losing everything else in the memory."
"A pa.s.sword?"
"Of some kind." Whitney had been searching the program list and had already checked the descriptions of two or three of the entries. Another of them caught his eye and he keyed it in. "You may need to check with ground control to even find the name... hold it. Never mind, I"ve found it. DCHECK. Let"s see...." He advanced the description another page, skimmed it. "Here it is. We need something called the Sasquatch-3L package to load it."
"Will Dallas ground control have it?" Henson asked.
"I would think so*if not, they can probably get it by phone from one of the Skyport maintenance areas." Whitney hesitated. "But it"s not clear whether or not that"ll do you any good."
"Why not?"
"Well, remember that the whole reason you don"t have the loading code in the first place is that they don"t want you accidentally plugging in the program and wiping out something the autopilot"s doing. So they may not legally be able to release the code to a Skyport crew, especially one that"s in flight."
"That"s stupid!"
"That"s bureaucratic thinking," Captain Kyser corrected*or agreed; Whitney couldn"t figure out which. Leaning over Whitney"s shoulder again, she spoke toward a small grille next to the display screen.
"Carl? Did you get all that?"
"Yes," the intercom answered, "and I suspect Mr. Whitney"s basically right. But there have to be emergency procedures for something like this*else why have the program stored aboard in the first place? It should simply be a matter of getting an adequately prominent official to give an okay. I"ll get the tower on it right away."
"And hope your prominent official can move his tail this early in the morning," she muttered under her breath.
Whitney had been thinking along a separate track. "There"s one other thing we can try," he said. "Can you patch me into the regular phone system from up here?"
"Trivially. Why?"
"I"d like to call my former supervisor back in Houston. He might be able to get the package, either from his own office or from someone in L.A.""You just said it was illegal to release the code," Henson objected.
"To you, yes; but maybe not to me. I work for the company, after all."
Henson started to growl something vituperative, but Kyser cut him off. "We"ll complain to the FAA later.
For now, let"s take whatever loopholes we can get our hands on. Put on that half-headset, Mr. Whitney, and I"ll fix you up with Ma Bell."
The call, once the connection was finally made, was a remarkably short one. Dr. Mills, seldom at his best in the early morning, nevertheless came fully awake as Whitney gave him a thumbnail sketch of the crisis.
He took down the names of both the diagnostic program and the loading code, extracted from Captain Kyser*via Whitney*the instructions for placing a return call to the Skyport, and promised to have the package for him in fifteen minutes.
"Well, that"s it, I guess," Whitney remarked after signing off. "Nothing to do now but wait."
"Yeah. d.a.m.n."
Whitney looked up at her as she stared through the computer console, concentration drawing her eyebrows together. She had been something of a surprise to him, and he still found it hard to believe a Skyport wing captain could be so young. Marinos, he estimated, was in his early fifties, and Henson wasn"t much younger. But if Betsy Kyser was anything past her early forties she was the best-preserved woman he"d ever seen. Which meant either United was hard up for Skyport personnel or Captain Kyser was one very fine pilot. He fixed the thought firmly in his mind; it was one of the few things about all this that was even remotely comforting. "Uh... Captain?" he spoke up.
She focused on him, the frown lingering for a second before she seemed to notice it and eased it a bit.
"Call me Betsy," she told him. "This isn"t much of a place for formalities."
"I"m Peter, then. May I ask why you need to know about the electronics right now? I would think the shuttle"s safety would be the thing you need to concentrate on."
"It is, but we can"t do anything about that until we"re sure more shuttles can dock safely." He must have looked blank, because the corner of her mouth twitched and she continued, "Look. Whatever we wind up doing to the shuttle, odds are we don"t already have the necessary equipment on board. That means*"
"That means you"ll have to bring it up via shuttle," Whitney nodded, catching on at last. "So you need to find the glitch in your docking program and make sure it hasn"t also affected the other modules"
equipment."
"Right. After that the next job"ll be to either get the pa.s.sengers out or secure the shuttle into the bay, whichever is faster and safer."
Whitney nodded again. In his mind"s eye he could see the damaged shuttle hanging precariously out the back of the Skyport, holding on by the barest of threads. The picture reawakened the half-forgotten vertigo of his first*and last*rollercoaster ride twenty years ago, and he discovered he was gripping the arms of his chair a shade more tightly than necessary. Firmly, he forced his emotions down out of the way. "There"s going to be a fair amount of drag on the shuttle from the Skyport"s slipstream,"
he commented, thinking aloud as a further distraction from discomfiting images. "That means a lot of stress on the docking collar. Would it help any if the shuttle dumped its fuel, to make itself lighter?"
"Just the opposite; the eng*" She paused, a strange look flickering across her face. Behind her,Whitney saw peripherally, Marinos had swiveled around, his attention presumably attracted by Betsy"s abrupt silence. "Paul," she said without turning, "run a calculation for me. At its present rate of burn, how much fuel has the shuttle got left?"
"What diff*?" Marinos stopped, too, the same look settling onto his own features. Turning back, he began punching calculator b.u.t.tons.
"Right," Betsy muttered tartly. "We"ve gotten too used to the easy transfer of fuel between shuttle and Skyport... or I have, anyway." Whitney had figured out what was going on, but Betsy spelled it out for him anyway. "You see, Peter, the shuttle"s currently firing its engines, at about medium power, to counteract the drag you mentioned. I guess I was subconsciously a.s.suming we could feed it all the fuel it needed from the Skyport"s reserves."
"But the connections are out of line?"
"Almost certainly. The fuel line"s on the starboard side, too, which means there"s not likely to be enough room to even get in and connect them manually. Probably no access panels close enough, either, but I guess we"ll have to check on that." She grimaced. "Something else to do. I hope someone"s keeping a list."
"Got it, Betsy," Marinos said, looking up once more. "At current usage, he"ll run dry in a little over seven hours."
"Seven hours." She pursed her lips. "And that a.s.sumes neither of his main pumps was rattled loose by the impact. Carl?"
