His mind came back to the vanishing airplanes. Historically, the Americans had managed to intercept one or two per month, that small a number despite all their radars and aircraft. But recently - four in the last two weeks, wasn't it? - had disappeared. What did that mean? Unknown to the Americans, there had always been "operational" losses, a military term that meant nothing more mysterious than flying accidents. One of the reasons that his boss had taken Carlos Larson on was to mitigate that wastage of resources, and it had, initially, shown promise - until very recently. Why the sudden jump in losses? If the Americans had somehow intercepted them, the air crews would have shown up in courtrooms and jails, wouldn't they? Cortez had to dismiss that thought.

Sabotage, perhaps? What if someone were placing explosives in the aircraft, like the Arab terrorists did...? Unlikely... or was it? Did anyone check for that? It wouldn't take much. Even minor damage to a low-flying aircraft could face the pilot with a problem whose solution required more time than he had in altitude. Even a single blasting cap could do it, not even a cubic centimeter... he'd have to check that out. But, then, who would be doing it? The Americans? But what if it became known that the Americans were placing bombs on aircraft? Would they take that political risk? Probably not. Who else, then? The Colombians might. Some senior Colombian military officer, operating entirely on his own... or in the pay of the yanquis ? That was possible. It couldn't be a government operation, Cortez was sure. There were too many informants there, too.

Would it have to be a bomb? Why not contaminated gasoline? Why not minor tampering with an engine, a frayed control cable... or a flight instrument. What was it that Larson had said about having to watch instruments at low level? What if some mechanic had altered the setting on the artificial horizon...? Or merely arranged for it to stop working... something in the electrical system, perhaps? How hard was it to make a small airplane stop flying? Whom to ask? Larson?

Cortez grumbled to himself. This was undirected speculation, decidedly unprofessional. There were countless possibilities. He knew that something was probably happening, but not what it was. And only probably, he admitted to himself. The unusually large number of missing aircraft could merely be a statistical anomaly - he didn't believe that, but forced himself to consider the possibility. A series of coincidences - there was not an intelligence academy in the world that encouraged its students to believe in coincidences, and yet how many strange coincidences had he encountered in his professional career?

"The rules are changing," he muttered to himself.

"What?" the driver asked.

"Back to the airport. My Caracas flight leaves in less than an hour."

" S , jefe ."

Cortez lifted off on time. He had to travel to Venezuela first for the obvious reasons. Moira might get curious, might want to see his ticket, might ask his flight number, and besides, American agents would be less interested in people who flew there than those who flew directly to Bogot . Four hours later he made his Avianca connection to El Dorado International Airport, where he met a private plane for the last hop over the mountains.

Equipment was issued as always, with a single exception. Chavez noted that nobody was signing for anything. That was a real break from routine. The Army always had people sign for their gear. If you broke it or lost it, well, though they might not make you pay for it, you had to account for it in one way or another. But not now.

The load- cuts differed slightly from one man to the next. Chavez, the squad scout, got the lightest load, while Julio Vega, one of the machine-gunners, got the heaviest. Ding got eleven magazines for his MP-5 submachine gun, a total of 330 rounds. The M-203 grenade launchers that two squad members had attached to their rifles were the only heavy firepower they'd be carrying in.

His uniform was not the usual stripe-and-splotch Army fatigue pattern, but rather rip-stop khaki because they weren't supposed to look like Americans to the casual observer, if any. Khaki clothing was not the least unusual in Colombia. Jungle fatigues were. A floppy green hat instead of a helmet, and a scarf to tie over his hair. A small can of green spray paint and two sticks of facial camouflage "makeup." A waterproof map case with several maps; Captain Ramirez got one also. Twelve feet of rope and a snaplink, issued to everyone. A short-range FM radio of an expensive commercial type that was nonetheless better and cheaper than the one the Army used. Seven-power compact binoculars, Japanese. American-style web gear of the type used by every Army in the world, actually made in Spain. Two one-quart canteens to hang on the web belt, and a third two-quart water bottle for his rucksack, American, commercial. A large supply of water-purification tablets - they'd resupply their own water, which wasn't a surprise.

Ding got a strobe light with an infrared cover lens because one of his jobs would be to select and mark helicopter landing zones, plus a VS-17 panel for the same purpose. A signaling mirror for times when a radio might not be appropriate (steel mirrors, moreover, do not break). A small flashlight; and a butane cigarette lighter, which was far better than carrying matches. A large bottle of extra-strength Tylenol, also known as "light-fighter candy." A bottle of prescription cough medicine, heavily laced with codeine. A small bottle of Vaseline petroleum jelly. A small squeeze bottle of concentrated CS tear gas. A weapons-cleaning kit, which included a toothbrush. Spare batteries for everything. A gas mask.

Chavez would travel light with but four hand grenades - Dutch NR-20 C1 type - and two smokes, also of Dutch manufacture. The rest of the squad got the Dutch frags, and some CS tear-gas grenades, also Dutch. In fact, all of the weapons carried by the squad and all of their ammunition had been purchased at Colon, Panama, in what was fast becoming the hemisphere's most convenient arms market. For anyone with cash there were weapons to be had.

Rations were the normal MREs. Water was the main hygienic concern, but they'd already been fully briefed about using their water-purification tablets. Whoever forgot had a supply of antidiarrhea pills that would follow a serious chewing from Captain Ramirez. Every man had gotten a new series of booster shots while still in Colorado against the spectrum of tropical diseases endemic to the area, and all carried an odorless insect repellent made for the military by the same company that produced the commercial product called "Off." The squad medic carried a full medical kit, and each rifleman had his own morphine Syrette and a plastic bottle of IV fluids for use as a blood-expander.

Chavez had a razor-sharp machete, a four-inch folding knife, and, of course, his three nonregulation throwing stars that Captain Ramirez didn't know about. With other sundry items, Chavez would be carrying a load of exactly fifty-eight pounds. That made his load the lightest in the squad. Vega and the other SAW gunner had the heaviest, with seventy-one pounds. Ding jostled the load around on his shoulders to get a feel for it, then adjusted the straps on his rucksack to make it as comfortable as possible. It was a futile exercise. He was packing a third of his body weight, which is about as much as a man can carry for any length of time without risking a physical breakdown. His boots were well broken-in, and he had extra pairs of dry socks.

"Ding, could you give me a hand with this?" Vega asked.

"Sure, Julio." Chavez took some slack in on one of the machine gunner's shoulder straps. "How's that?"

"Just right, ' mano . Jeez, carrying the biggest gun do have a price."
