Commander Jensen finished tanking his aircraft, disconnecting from the K.A-6 as soon as his fuel gauges pegged. He recovered the refueling probe and maneuvered downward to allow the tanker to clear the area. The mission profile could hardly have been easier. He eased the stick to the right, taking a heading of one-one-five and leveling off at thirty thousand feet. His IFF transponder was switched off at the moment, and he was able to relax and enjoy the ride, something he almost always did. The pilot's seat in the Intruder is set rather high for good visibility during a bomb run - it did make you feel a little exposed when you were being shot at, he remembered. Jensen had done a few missions before the end of the Vietnam War, and he could vividly recall the 100mm flak over Haiphong, like black cotton balls with evil red hearts. But not tonight. The seat placement now was like a throne in the sky. The stars were bright. The waning moon would soon rise. And all was right with the world. Added to that was his mission. It didn't get any better than this. With only starlight to see by they could pick out the coast from over two hundred miles away. The Intruder was cruising along at just under five hundred knots. Jensen brought the stick to the right as soon as he was beyond the radar coverage from the E-2C, taking a more southerly heading toward Ecuador. On crossing the coast he turned left to trace along the spine of the Andes. At this point he flipped on his IFF transponder. Neither Ecuador nor Colombia had an air-defense radar network. It was an extravagance that neither country needed. As a result, the only radars that were now showing up on the Intruder's ESM monitors were the usual air-traffic-control type. They were quite modern. A little-known paradox of radar technology was that these new, modern radars didn't really detect aircraft at all. Instead they detected radar transponders. Every commercial aircraft in the world carried a small "black box" - as aircraft electronic equipment is invariably known - that noted receipt of a radar signal and replied with its own signal, giving aircraft identification and other relevant information which was then "painted" on the control scopes at the radar station - most often an airport down here - for the controllers to use. It was cheaper and more reliable than the older radars that did "skin-paints," detecting the aircraft merely as nameless blips whose identity, course, and speed then had to be established by the chronically overworked people on the ground. It was an odd footnote in the history of technology that the new scheme was a step both forward and backward.
The Intruder soon entered the air-control zone belonging to El Dorado International Airport outside Bogot . A radar controller there called the Intruder as soon as its alphanumeric code appeared on his scope.
"Roger, El Dorado," Commander Jensen replied at once. "This is Four-Three Kilo. We are Inter-America Cargo Flight Six out of Quito, bound for LAX. Altitude three-zero-zero, course three-five-zero, speed four-nine-five. Over."
The controller verified, the track with his radar data and replied in English, which is the language of international air travel. "Four-Three Kilo, roger, copy. Be advised no traffic in your area. Weather CAVU. Maintain course and altitude. Over."
"Roger, thank you, and good night, sir." Jensen killed the radio and spoke over his intercom to his bombardier-navigator. "That was easy enough, wasn't it? Let's get to work."
In the right seat, set slightly below and behind the pilot's, the naval flight officer got on his own radio after he activated the TRAM pod that hung on the Intruder's center-line hardpoint.
At T minus fifteen minutes, Larson lifted his cellular phone and dialed the proper number. "

"Wagner," another voice replied a moment later. "Who is this?"
Larson took the cellophane from off a pack of cigarettes and crumpled it over the receiver while he spoke garbled fragments of words, then finally: "I can't hear you, Carlos. I will call back in a few minutes." Larson pressed the kill button on the phone. This location was at the far edge of the cellular system anyway.
"Nice touch," Clark said approvingly. "Wagner?"
"His dad was a sergeant in the
"Christmas," Mr. Clark observed. The radio made the next sound, five minutes later.
"Bravo Whiskey, this is Zulu X-Ray, over."
"Zulu X- Ray, this is Bravo Whiskey. I read you five-by-five. Over," Larson answered at once. His radio was the sort used by forward air controllers, encrypted UHF.
