measurements, we must position ourselves here,” the goateed Ukrainian said, pointing to a map of the North American seaboard. “One hundred and five kilometers from the coast.”
Tongju studied the position silently for a minute, calculating the added distance to cover. The proposed position was dangerously near the coastline, he observed, noting a pair of offshore islands in close proximity. But they could reach the spot and still launch within Kang's desired time schedule. As all eyes in the room waited for his command, he finally turned and nodded toward Lee. “Alter course at once. We will position both vessels at the new position before dawn and initiate launch countdown at daybreak.”
You've got to be kidding me. A blimp?“ Giordino scratched his chin, then shook his head at Pitt. ”You dragged me all the way across country to go for a ride in a blimp?'
“I believe the preferred term is airship” Pitt said, throwing his partner a mock look of indignation.
“A gasbag, by any other name.”
Giordino had wondered what Pitt had up his sleeve after the two arrived at LAX on an overnight flight from Washington. Rather than heading south from the airport, toward the Port of Los Angeles and adjacent Coast Guard Marine Safety regional command, Pitt had turned their rental car north. Giordino promptly fell asleep in the passenger seat as the head of NUMA drove them out of the Los Angeles metro area. Awakening later to find the specter of strawberry fields rushing past the window, he rubbed his eyes as the car entered the tiny Oxnard Airport and Pitt parked the vehicle near a large blimp moored to a truck-mounted vertical boom.
Peering at the blimp, Giordino cracked, “I didn't think the Super Bowl was scheduled for another couple of months.”
The 222-foot long Airship Management Services Sentinel 1000 was, in fact, much larger than the usual advertising blimps seen hovering over football games and golf tournaments. An enlarged version of the company's popular Skyship 600 series of blimps, the Sentinel 1000 was designed to lift a useful load of nearly six thousand pounds by way of an envelope that held ten thousand cubic meters of gas. Unlike the rigidly framed dirigibles of the twenties and thirties that relied on highly flammable hydrogen for lift, the Sentinel 1000 was a true non-rigid blimp that utilized the safer element of helium to rise off the ground.
“Looks like a runt nephew of the Hindenburg” Giordino moaned, eyeing the silver-skinned airship warily.
“You happen to be looking at the latest in surveillance and tracking technology,” Pitt said. “She's fitted with a LASH optical system. NUMA is testing her out for possible survey use on coral reef and tide studies. The system has already been used successfully to track migrating whales.”
“What is a ”LASH system?'
“Stands for ”Littoral Airborne Sensor-Hyperspectral.“ It's an optical imaging system that uses a breakdown in the color band to detect and track targets that the eye cannot see. Homeland Security is considering using it for border security and the Navy for antisubmarine warfare.”
“If we can give it a test run over Malibu Beach, then I'm all for it.” A ground crewman wearing a NUMA identification badge climbed out of the gondola as Pitt and Giordino approached the airship.
“Mr. Pitt? We've installed the radio set that the Coast Guard sent up, so you'll be able to conduct secure communications with their vessels. The Icarus has been weighed off for a landing equilibrium of plus-one hundred kilograms when your fuel supply runs down to five percent, so just don't run the tanks dry. The airship is also fitted with both a water ballast system and an experimental fuel dump release, should you need emergency lift.”
“How long can we stay aloft?” Giordino asked, eyeing a pair of ducted propellers jutting from either side of the gondola's aft section.
“Eight to ten hours, if you go easy on the throttles. Enjoy your flight, she's a joy to fly,” he said, bowing slightly.
Pitt and Giordino climbed through the gondola door and into a spacious cabin that was comfortably outfitted to seat eight passengers. Squirming through a forward opening into the flight compartment, Pitt took up the pilot's controls while Giordino plopped into the copilot's seat. With a muffled roar, Pitt started the pair of turbocharged Porsche 930 air-cooled engines mounted on the rear flanks of the gondola, which served as propulsion. With the engines idling, Pitt obtained clearance to take off from the airport control tower, then turned to Giordino.
“Ready for takeoff, Wilbur?”
“Ready when you are, Orville.”
Launching the blimp was not a simple action handled solely by the pilots but rather a carefully orchestrated maneuver assisted by a large ground crew. Outside the gondola, the Icaruis support crew, all attired in bright red shirts, took up positions around the airship. A pair of ropes attached to the blimp's nose were pulled taut by three men standing off either side of the bow while four additional men grabbed onto side rails running the length of the gondola. Directly forward of the wide cockpit window that ran nearly to his feet, Pitt stared toward the crew chief, who stood at the base of the mobile mooring mast. At Pitt's command, the crew chief signaled another crewman, standing high atop the mooring mast, to release the nose tether. In unison, the ground crew then tugged at the weightless blimp, walking it away from the mooring mast several dozen yards to a safe launching point clear of obstacles.
Pitt gave a thumbs-up signal to the crew chief, then reached over and pulled down a pair of levers protruding from the center console, increasing the throttle to the twin engines. As the ground crew let free of their clutches and moved clear, he gently pulled back on a center yoke control mounted in front of his seat. The controls manipulated the motor-driven propellers, which were each enclosed in swiveling ducts. As he pulled on the yoke, the ducts tilted upward, providing additional lift from the churning propellers. Immediately, the blimp began to rise, creeping forward as it climbed. Almost without the feeling of movement, the big airship rose off the ground and into the sky with its nose pointed high. Giordino cheerfully waved out an open side window to the ground crew below, who shrank to the size of bugs as the airship rapidly gained altitude.
Despite Giordino's request for a low-flying pass over Malibu, Pitt steered the airship directly offshore from Oxnard after leaving the grounds of the airport and soon leveled the blimp off at a height of twenty-five hundred feet. The Pacific Ocean resonated a deep aqua color under a bright sun, and the men easily counted out the northerly Channel Islands of Santa Cruz, Santa Rosa, and San Miguel under the clear skies. As they floated east, Pitt noticed dew dripping off of the blimp, its fabric sides warming under the rays of the morning sun. He glanced at a helium pressure gauge, noting a slight rise in the needle as the helium expanded from the warming temperatures and higher cruising altitude. An automatic venting system would release any excess gas if the pressure rose too high, but Pitt kept the blimp well below its pressure height so as not to needlessly stave off helium.
The controls of the Sentinel 1000 were heavy in his hands and he noted that the sensation of flying the blimp felt closer to sailing a twenty-meter racing yacht than piloting an airplane. Turning the huge rudders and elevators required some muscling of the yoke, which resulted in an anxious pause before the ship's nose would gradually respond. Correcting course, he absentmindedly watched the lines dangling off the blimp's nose sway back and forth. A boat bobbed into view beneath them, which he recognized as a charter fishing boat. The tiny-looking day fishermen on the boat's stern suddenly waved up at them with friendly abandon. There was something about an airship that always seemed to strike a warm chord with people. They captured the romance of the air, Pitt decided, offering a reminder of times past when flying was still a novelty. With his hands on the controls, he could feel the nostalgia himself. Floating at a leisurely pace over the water, he let his mind churn back to the days of the thirties when mammoth dirigibles like the Graf Zeppelin and Hindenburg shared the skies with the huge Navy airships Akron and Macon. Like the opulent cruise ships of the same era, they offered a certain relaxed majesty that simply no longer existed in modern travel.
When they reached a distance of thirty miles offshore, Pitt angled the blimp south and began navigating a large, lazy arc off the Los Angeles metropolis. Giordino powered up the LASH optical system, tied into a laptop computer, which enabled him to spot the images of incoming surface vessels up to thirty-five miles away. The freighters and containerships came chugging in toward the ports of Los Angeles and Long Beach at a sporadic yet endless pace. The big vessels hailed from a variety of exotic-sounding home ports from Mumbai to Jakarta, though China, Japan, and Taiwan accounted for the largest volume of traffic. More than three thousand vessels a year entered the adjacent ports, creating a constant stream of traffic that crawled across the Pacific toward America's busiest port like ants to a picnic. As Giordino studied the laptop, he reported to Pitt that he could spot two large vessels inbound in the distance that figured to be commercial ships. Squinting out the cockpit window, Pitt could just make out the leading vessel on the horizon.
