"We're approaching the lower half of our grid," Pitt said over his shoulder to Gu
"Circle around for a couple of minutes while I set up the system," Gu
"As you wish." Giordino nodded, moving from his seat to the rear of the cabin.
Pitt said, "I'll head toward the starting point for our first run and hang around until you're ready."
Giordino lifted the sensor. It was shaped like an air-to-air missile. He lowered it through a floor hatch of the helicopter. Then he unreeled the sensor on its umbilical cable. "Tow bird out about thirty meters," he a
"I'm picking up interference from the helicopter," said Gu
Giordino complied. "How's that?"
"Good. Now hold on while I set the digital and analog recorders."
"What about the camera and data acquisition systems?"
"Them too."
"No need to hurry," said Pitt. "I'm still programming my grid lane data into the satellite navigation computer."
"First time with a Geometrics G-8136?" Giordino asked Gu
Gu
"Dirk and I used a G-8136 to locate a Chinese airliner that crashed off Japan last year. Worked like a woman of virtue-sensitive, reliable, never drifted, and required no calibration adjustments. Obviously, my ideal for a mate."
Gu
"He has this thing for robots," Pitt joked.
"Say no more," Giordino said pretentiously. "Say no more."
"I'm told this model is good for accurate data on small anomalies," said Gu
Giordino returned to the copilot's seat, settled in and stared down at the unbroken carpet of green no more than 200 meters (656 feet) below. There wasn't a piece of ground showing anywhere. "I don't think I'd like to spend my holidays here."
"Not many people do," said Pitt. "According to Julien Perlmutter, a check of local historical archives came up with the rumor that the local farmers shun the area. Julien said Cuttill's journal mentioned that mummies of long dead Inca were torn from graveyards by the tidal wave before being swept into the jungle. The natives are highly superstitious, and they believe the spirits of their ancestors still drift through the jungle in search of their original graves."
"You can run your first lane," declared Gu
"How far from the coast are we going to start mowing the lawn?" Giordino asked, referring to the seventy-five meter wide grid lanes they pla
"We'll begin at the three-kilometer mark and run parallel to the shore," answered Pitt, "ru
"Length of lanes?" inquired Gu
"Two kilometers at a speed of twenty knots."
"We can run much faster," said Gu
"We'll take it nice and slow," Pitt said firmly. "If we don't fly directly over the target, any magnetic field we hope to find won't make much of an impression on your gamma readings."
"And if we don't pick up an anomaly, we increase the perimeters of the grid."
"Right. We'll conduct a textbook search. We've done it more times than I care to count." Then Pitt glanced over at Giordino. "Al, you mind our altitude while I concentrate on our lane coordinates."
Giordino nodded. "I'll keep the tow bird as low as I can without losing it in the branches of a tree."
The sun was up now and the sky was clear of all but a few small, wispy clouds. Pitt took a final look at the instruments and then nodded. "Okay, guys, let's find ourselves a shipwreck."
Back and forth over the thick jungle they flew, the air-conditioning system keeping the hot, humid atmosphere outside the aircraft's aluminum skin. The day wore on and by noon they had achieved nothing. The magnetometer failed to register so much as a tick. To someone who had never searched for an unseen object, it might have seemed discouraging, but Pitt, Giordino, and Gu
Pitt was also a stickler for the game plan. He knew from experience that impatience and deviation from the computed search lanes usually spelled disaster for a project. Rather than begin in the middle of the grid and work out, he preferred to start at the outer edge and work in. Too often a target was discovered where it was not supposed to be. He also found it expedient to eliminate the open, dry areas so no time was wasted reru
"How much have we covered?" asked Gu
"Two kilometers into the grid," Pitt answered. "We're only now coming into Yaeger's prime target area."
"Then we're about to run parallel lines five kilometers from the 1578 shoreline."
"Yes, the distance the wave carried the galleon, as indicated by Yaeger's computer program."
"Three hours of fuel left," said Giordino, tapping the two fuel gauges. He showed no sign of fatigue or boredom, if anything he seemed to be enjoying himself.
Pitt pulled a board with a chart clipped to it from a side pocket of his seat and studied it no more than five seconds. "The port city of Manta is only fifty-five klicks away. They have a good-sized airport where we can refuel."
"Speaking of refueling," said Gu
"Weird tasting cheese," muttered Giordino, examining the inside of his sandwich with a cynical eye.
Gu
Two hours and fifteen minutes later they had traveled the twenty-eight lanes it took to cover kilometers five and six. They definitely had a problem now as they were beyond Yaeger's estimated target site. None of them believed a tidal wave could carry a 570-ton ship more than 5 kilometers (3 miles) over land from the sea. Certainly not a wave with a crest less than 30 meters (98 feet) high. Their confidence ebbed as they worked farther out of the prime search area.
"Begi
"Too far, way too far," Giordino muttered.
"I agree," said Gu
"We'll finish kilometer seven," Pitt said, his eyes locked on the navigational instrument displaying his coordinates.
