Seagull deterrence wasn’t something he had studied before, but he found that there was a large body of work on the subject, the result of a few high-profile disasters of commercial airlines ingesting seagulls in their engines during takeoff. (There was also the oddity that worldwide, many airports were located near garbage dumps, exacerbating the problem.) Following the advice of experts, they first tried scaring the birds away with shotgun blasts and sirens, but the canny gulls soon realized that the noises weren’t lethal and returned to the island, spreading their waste all over the bodies of Hamlin’s highly engineered drones as they ignored the noise. Next, the Alliance imported a family of spirited Brittany spaniels to chase the birds off, but the dogs soon grew lazy in the island heat. Throughout, Pete’s engineering team took careful readings of the solar cells and battery charges that confirmed that the batteries were slow to charge and that the situation was getting worse as gulls continued to manufacture excrement at a rate that seemed nearly supernatural.
Pete had no doubt that once the drones took to the air, the problem would fix itself. The drones were designed to stay aloft for long periods of time, landing only when they needed to refuel or rearm. Having the whole fleet on the ground at once for the gulls to attack would never happen again, and hopefully the continuous takeoffs and landings would frighten the birds away. More important, the drone force would be largely autonomous. Once the initial launch was complete, most of the island’s human residents would depart, taking with them the bread crumbs and pizza crusts that the gulls found so appetizing. Once the drones deployed, Pete was confident, the bird problem would go away. But in the meantime they had a thousand stationary drones on the tarmac, and their batteries needed to be charged, which meant their solar cells had to be clean. Which was why he was standing in the middle of the tarmac with a fake falcon in his hands.
“Are we ready?” asked Admiral Stewart.
Pete jumped, and smiled. “You startled me.”
“I can tell,” he said. Admiral Wesley Stewart had been Hamlin’s opponent at first, an intense one at times, but he was fiercely intelligent and possessed a brilliant military mind. Hamlin was glad he was here for the launch. He realized that men like Stewart, even if they were beholden to an older style of warfare, would be vital in the coming fight. And to his credit, Stewart, once he had his orders to mobilize a submarine fleet such as the world had never seen, had fulfilled his mission with heroic speed and effectiveness.
He pointed at the bird in Pete’s hands. “This sounded like something I would want to see in person.” Gulls swooped and soared around them, leaving a small bubble of space around the two men but covering all the other drones that weren’t immediately in reach. Pete held out the fake falcon so the admiral could take a look. Even up close it was a convincing fake, lovingly painted to look like a peregrine falcon, from its painted-on tail feathers to its menacing, sharp eyes and pointy beak.
“You really think this is going to work?”
“The brochure said it would,” said Pete. The admiral laughed.
Pete turned to the tower and waved. The Robobird had arrived just the day before, so, mercifully, they’d had no time to develop a detailed procedure for what they were about to do. This would be an operation of pure trial and error. Pete was certain that, should the Robobird be successful, its success would be followed by many pages of Alliance doctrine and formalized procedures.
“Power it up?” asked the admiral. Pete nodded. The admiral pushed the green central button on the remote control he held, and its big wings began to flap. Pete was surprised at how much force it now took to hold it in place, the robot straining to take flight. Before he lost control of it completely, remembering what he’d read in the Robobird’s scant instruction manual, he threw the fake bird up and away, with a motion like he used to throw paper airplanes as a child.
It immediately flew away, wings pumping, looking for all the world like a real falcon. Pete took the controller from the admiral.
The Robobird had been invented by an eccentric pair of brothers in the Netherlands. They’d originally designed it for farmers, who hated seagulls for the way they could pick a freshly planted field clean in hours. But the Robobird had quickly found a following in the aviation community, for reasons that Pete immediately understood.
“My goodness,” said the admiral as the fake bird took flight.
“Pretty good replica, right?”
“I’d say so,” said the admiral. “What is that thing made out of?”
“Glass fiber and nylon composite,” said Pete.
“Like…”
“Yes,” Pete said, smiling, “just like our birds.”
When the bird reached altitude, Pete made it stop flapping. It banked and glided into the wind — just like a real falcon. Pete had spent his life studying machines that fly, but he’d never seen anything like this. He pulled it around into a tight loop, then with a couple of flaps propelled it upward again.
“Having fun?” said the admiral.
“Even if it doesn’t scare the gulls, I’m keeping this thing,” said Pete.
It was high above them now. “Let’s see if can scare a seagull.” Pete turned the bird into a dive and had it fly straight down toward a pack of loitering gulls.
“Here we go!” said the admiral.
The Robobird dived sharply with its convincing fake wings tucked behind it. It dropped right over the center of the airfield and then pulled up.
Fifty seagulls scattered instantly, in a squawking panic.
They landed a few dozen feet away, on another column of Pete’s grounded drones, but he had the Robobird follow them; this time they flew away with even greater urgency, sensing they were being pursued. They in turn alerted every bird they passed, until the skies were filled with noisy, panicked gulls.
Some peeled off from the group and tried to return, but Pete turned the Robobird and chased them back into the fleeing group. Pete had, in ten minutes, mastered the operation of the Robobird.
Within thirty minutes, there wasn’t a single seagull on the tarmac.
“I think that thing works!” said the admiral.
“And,” said Pete, chasing off a small pod of birds, “it’s a hell of a lot of fun.”
“My turn,” said the admiral, reaching for the controller.
“Take it,” said Pete, hating to give it up but eager to proceed. “I’ll get a crew down here to wash these drones.”
The next morning at dawn he walked the tarmac once again, among the orderly rows of now pristine drones. Some of them were still damp from the efforts of the crew that had spent all night washing their black, composite skin, and they gleamed in the early sun. They seemed to throb with potential energy as they gathered up sunlight and stored it deep in their batteries. He stopped and put his hand on one of them. It was low enough that he had to kneel. Just five feet and six inches long, and almost exactly twice as wide. The long, swept wings made it look like a glider, which, in fact, it was designed to be whenever possible to conserve energy. But a small, rear-mounted propeller provided the real thrust, the killing speed. On a bright day, with no targets to pursue, it would actually gain energy in the sky, storing more power from the solar cells that covered its wings than it burned by turning the propeller. The entire drone weighed just forty pounds, and carried a single bomb that weighed ten. It could soar as high as twenty thousand feet, and fly as fast as 80 knots. In a dive, it could go even faster. Its composite material was at once featherlight and incredibly strong; it felt warm against the palm of his hand, almost alive.
