〃Dr。 Kurt Perry； a brilliant biochemist。〃
The President nodded at Fawcett。 〃Let's see that he receives a proper ceremony。〃
There was a slight pause； and then Post brought the discussion back on track。 〃Okay； if the Soviets didn't get Jersey colony； what are they left with？〃
〃The。 Gettysburg；〃 Hudson answered。 〃The Russians still have a chance at pirating a treasure trove of scientific data。〃
〃By snatching the shuttle out of the air？〃 Simmons stated sarcastically。 〃News to me they have Buck Rogers on their side。〃
〃They don't need him；〃 Hudson retorted。 〃It's technically possible to program a deviation into the flight guidance systems。 The puters can be fooled into sending the wrong signal to the drive elevons； the thrusters； and other equipment to control the Gettysburg。 There are a thousand different way to nudge the shuttle off its course a few degrees。 Depending on the distance from touchdown； it could be thrown off as far as a thousand miles from the Kennedy spaceport at Cape Canaveral。〃
〃But the pilots can override the automated system and land on manual control；〃 protested Post。
〃Not if they're conned into thinking Houston Control is monitoring their return flight path。〃
〃Is this possible？〃 asked the President incredulously。
Alan Mercier nodded。 〃Providing the Soviets have local transmitters with the capacity to overpower the shuttle's internal electronics and jam all signals from Houston Control。〃
The President exchanged grim looks with Brogan。
〃Cayo Santa Maria；〃 Brogan muttered miserably。
〃An island north of Cuba containing a powerful transmission and listening facility with the necessary muscle to do the job；〃 the President explained to the others。
〃Maybe they haven't caught on that our colonists have left the moon；〃 Fawcett said hopefully。
〃They know；〃 replied Hudson。 〃Once their eavesdropping satellites were aimed toward Jersey Colony； they've monitored every one of our transmissions。〃
〃We'll have to e up with a plan to neutralize the island's equipment；〃 suggested Post。
Brogan smiled。 〃Just so happens there is an operation in the works。〃
Post smiled back。 〃If you're scheming what I'm thinking； all I'd like to know is when。〃
〃There is talk purely a rumor； mind you that Cuban military forces are going to launch an attack…and…destroy mission sometime after midnight tonight。〃
〃And the departure time of the shuttle for home？〃 asked Alan Mercier。
〃0500 tomorrow；〃 Post answered。
〃That settles it；〃 said the President。 〃Inform the mander of Columbus to hold Gettysburg on the docking platform until we can guarantee its safe return。〃
Everyone around the table seemed satisfied for the moment； except Hudson。 He had the look of a boy who had just lost his puppy to the county dogcatcher。
〃I just wish；〃 he muttered to no one in particular； 〃it was all that easy。〃
Velikov and Maisky stood on a balcony three levels above the electronic listening center and looked down on a small army of men and women who manned the sophisticated electronic receiving equipment。 Twenty…four hours a day； giant antennas on Cuba intercepted United States civilian telephone calls and military radio signals； relaying them to Cayo Santa Maria； where they were fed into the puters for decoding and analysis。
〃A truly superb job； General；〃 said Maisky。 〃The reports on your installation have been far too modest。〃
〃A day doesn't go by when we don't continue the expansion；〃 Velikov said proudly。 〃Besides the business end of the plex there is a well…supplied dining room and a physical conditioning center with exercise equipment and a sauna。 We even have an entertainment room and a barber shop。〃
Maisky's gaze rose to two screens； each ten by fifteen feet； on different walls。 The left screen contained puter…generated displays while the right showed various data and intricate graphs。
〃Have your people discovered the status of the moon colonists yet？〃
The general nodded and picked up a telephone。 He spoke a few words into the receiver while looking down on the busy equipment floor。 A staff member at a console looked up and waved a hand。 Then the two screens went dark for a brief instant and returned to life with a new data display。
〃A plete rundown；〃 said Velikov； pointing to the right screen。 〃We can monitor almost everything that is transmitted between their astronauts and Houston Control。 As you can see； the moon colonists' lunar transporter docked three hours ago at the space station。〃
Maisky was fascinated as his eyes traveled over the display information。 He could not bring himself to accept the fact that American intelligence undoubtedly knew as much if not more about Soviet space efforts。
〃Do they transmit in code？〃 he asked。
〃Occasionally； if it is a military mission； but NASA usually talks to their astronauts quite openly。〃
〃As you can see on the data display； the Houston Ground Control Center has ordered the Gettysburg to postpone its scheduled departure for tomorrow morning。〃
〃I don't like the look of that。〃
〃I see nothing suspicious。 The President probably wants time to mount a massive propaganda campaign to announce another American space triumph。〃
〃Or they may be wise to our intentions。〃 Maisky then became quiet； lost in thought。 His eyes had a worried look； and he clasped and unclasped his hands nervously。
Velikov looked at him with amusement。 〃If this in any way upsets your plans； I could break in on Houston Control's frequency and issue a false mand。〃
〃You can do that？〃
〃I can。〃
〃Simulate an order for the shuttle to depart the space station for reentry？〃
〃Yes。〃
〃And deceive the manders of the station and the shuttle into believing they're hearing a familiar voice？〃
〃They'll never detect the difference。 Our puterized synthesizers have more than enough taped transmissions to perfectly imitate voice； accent； and verbal mannerisms of at least twenty different officials of NASA。〃
〃What's to stop Houston Control from countermanding the order？〃
〃I can scramble their transmissions until it's too late for them to stop the shuttle。 Then； if the instructions you gave us from our space scientists are correct； we'll override the craft's flight systems and bring her down at Santa Clara。〃
Maisky looked at Velikov long and steadily。 Then he said； 〃Do it。〃
The President was dead asleep when the phone beside his bed softly chimed。 He rolled over and read the luminous dial on his wristwatch。 Ten minutes after one in the morning。 Then he answered。 〃Go ahead。〃
The voice that replied was Dan Fawcett's。 〃Sorry to wake you； Mr。 President； but something has e up that I thought you'd want to know about。〃
〃I'm listening。 What is it？〃
〃I've just received a call from Irwin Mitchell at NASA。 He said the Gettysburg has cast off from Columbus and is orbiting in preparation for reentry。〃
The President sat bolt upright； waking his wife beside him。 〃Who gave the order？〃 he demanded。
〃Mitchell can't say。 All munication between Houston and the space station is down because of some strange interference。〃
〃Then how has he confirmed the shuttle's departure？〃
〃General Fisher has been tracking and monitoring Columbus at the Space Operations Center in Colorado Springs since Steinmetz left Jersey Colony。 The sensitive cameras at the center caught the movement when Gettysburg left the station's dock。 He called me as soon as he was informed。〃
The President pounded the mattress in dismay。 〃Damn！〃
〃I took the liberty of alerting Jess Simmons。 He's already scrambled two Air Force tactical squadrons into the air to fly escort and protect the shuttle as soon as she drops through the atmosphere。〃
〃How much time do we have before the Gettysburg lands？〃
〃From initial descent preparation to touchdown； about two hours。〃
〃The Russians are behind this。〃
〃The general consensus；〃 acknowledged Fawcett。 〃We can't be sure yet； but all indications point to Cuba as the source of Houston's radio interference problem。〃
〃When does Brogan's special team hit Cayo Santa Maria？〃
〃0200 hours。〃
〃Who's leading them in？〃
〃One moment while I look up the name in yesterday's CIA report。〃 Fawcett left the line for no more than thirty seconds before he returned。 〃The mission is being directed by Marine Colonel Ramon Kleist。〃
〃I know the name。 Kleist was a Congressional Medal of Honor winner。〃
〃Here's something else。〃
〃What？〃
〃Kleist's men are being guided by Dirk Pitt。〃
The President sighed almost sadly。 〃He's already given too much。 Is his presence absolutely required？〃
〃It was Pitt or nobody；〃 said Fawcett。
〃Can they destroy the jamming center in time？〃
〃In all honesty； I'd have to say it's a toss…up。〃
〃Tell Jess Simmons to stand by in the War Room；〃 said the President solemnly。 〃If anything goes wrong； I fear the only alternative left for us to keep the Gettysburg and her valuable cargo out of Soviet hands is to shoot her down。 Do you read me； Dan？〃
〃Yes； sir；〃 Fawcett said； his face suddenly white。 〃I'll give hi
