039 Chapter 39 Freedom of Navigation

The entrance of the cave is a stone platform protruding three or four meters outward, only more than 20 meters from the ground, the predator drone swept over the cliff from an ultra-low altitude of two or three hundred meters, Wang Xiaoyu just appeared in front of the belly of the aircraft, and was immediately discovered by the infrared image machine of the predator drone, and the two cameras under the belly of the machine turned to his side, and transmitted the movements around Wang Xiaoyu back in real time. But the drone operator was still faithfully carrying out the order to attack Yang Xue, roaring towards Wang Xiaoyu's head.

Wang Xiaoyu saw a red beam of light shot out of the head of the Predator drone, and his heart was half cold, he knew that it was the drone's laser sight that began to work, and in a few seconds, the missile would be launched, and the grass was next to Yang Xue and the three of them.

In desperation, he pulled out his M911 pistol, looked at the Predator drone that had already flown overhead, and aimed at it in mid-air. A shot of "Bah" was fired, and Wang Xiaoyu felt that he was aiming very accurately, but the drone did not change, and flew straight towards him, as if he did not shoot. Only the bullet casings that bounced out of the chamber of the gun hit the stones next to the cliff, making a crisp sound of the metal and copper shells hitting the stones, reminding him that he had indeed fired.

He gritted his teeth, forced himself to calm down, and pointed at the belly of the Predator drone, "Bah, Bah, Bah" fired three shots in one breath, three .45 caliber warheads flew out of the chamber one after another, and the moment the bullet was fired, three circles of fire came out of the muzzle, with his hope and Yang Xue's chance of survival, and shot at the drone. As the saying goes, the higher the expectation, the greater the disappointment, he still didn't see any change in the drone, only three bullet shells popped out of the chamber, tumbling and falling down the cliff, his mood at the moment, with the bullet shells that fell into the cliff quickly fell to the bottom.

The Predator drone had flown overhead, flashing signal lights in its belly, and then whizzed over his head with its two drooping tails. Cold sweat broke out on his forehead, and his hands holding the gun were trembling slightly, knowing that he couldn't hesitate any longer, the platform on this cliff was the only obstacle that could affect the launch window of the Predator drone, and after crossing it, he reached the sky above the grass, and Yang Xue and the others had nothing to hide next to the grass. As soon as he gritted his teeth, he fired four shots in a row, but before he could let go of the finger that was hooking the trigger, he only heard a clicking sound from the bolt, and the bullet had already been shot by him.

He couldn't see where the bullets had gone, but it was certain that the Predator drone was still unharmed, flying straight towards the meadow, and did not find the string of bullets that were sending it off behind it. Only the bullet casings clanged as they hit the stones on the ground, as if mocking Wang Xiaoyu's incompetence.

He knew that things were going to go bad, and he complained in his heart that he was useless, and such a large plane could not hit. This will watch the drone fly towards Yang Xue, but there is nothing to be done. He had a feeling of wanting to cry, and he had an urge to kill, so he hurriedly threw the M911 pistol with empty bullets in his hand towards the drone in mid-air, and scolded: "M countryman, I'm CAO your grandmother!" ”

The M911 pistol rolled in the air and drew an arc, flew more than 30 meters, and then fell weakly down the cliff.

In fact, the effective range of the M911 pistol is only 50 meters, and the Predator drone is at least 200 meters above his head, even if he is a sharpshooter, it will not help. Besides, the lethality of the pistol is insignificant for a drone protected by a metal shell, and even if it hits, it may not be able to cause much damage.

In the blink of an eye, the drone had already swept over the cliff, less than 200 meters away from Yang Xue and them, and there was no obstacle in front of them, and it entered the best angle to launch the missile. Wang Xiaoyu saw that the missile hook of the Predator drone lit up with a red signal light, and the last Hellfire missile under the belly of the plane was slowly rotating and fine-tuning, aiming at the grass. He closed his eyes in pain, tears streaming down his face. In his heart, there was a sense of helpless despair, even if he was trapped in this cave with no way to the world, and there were pursuers behind him, he still had a strong belief that he could turn the corner into safety. At this moment, watching the ravages of the Predator drone, but he can't do anything, in front of the army, do the people only have to wait for death? I can't help but feel a deep sense of powerlessness.

However, an unbelievable scene happened, the Predator drone, which was about to launch a missile, suddenly raised its nose, and then pulled up, whistling over the heads of Yang Xue and the others, and the thick banyan tree swayed endlessly, and it flew towards the exit at the other end of the valley. It didn't launch missiles, it didn't strafe, it didn't attack, it only the wind from the tail, and the forest sea below the belly of the plane was flooded with a green wave. Wang Xiaoyukou was stunned and puzzled.

Not only Wang Xiaoyu couldn't figure out why this happened? Even Carl. Sergeant Benjamin, the drone operator on the nuclear-powered aircraft carrier USS Vincennes, couldn't figure it out either, everything was ready, why did Colonel King cancel the attack?

On the large screen behind the drone's ground station, an image is switched to show a cliff, which Sergeant Benjamin recognizes as the one below the drone.

Then came Colonel King's words: "Suspend the attack on the woman in the woods, the suspect is in the cave, and pay attention to the objects on the pine treetops at the entrance of the cave."

"Inexplicable", Sergeant Benjamin muttered, putting a good target and not hitting, but going to see some pine trees, is this CIA colonel in the water in his head? Benjamin thought so in his heart, but he didn't dare to say it, there was an unwritten tradition in the M Army, CIA officers were more powerful than ordinary officers, and even the commander of this aircraft carrier group, Major General Jefferson, wanted to give this Colonel King three points, and he didn't dare to talk too much as a small sergeant. So he made a turn over the valley and flew close to the rock wall.

There is a reason why Colonel King canceled the attack, because when the drone flew over the cliff, he found a woman on the cliff walking towards the cave, and she couldn't see her face clearly, leaving only a blonde haired back, and Colonel Kim recognized this at a glance as the foreign girl Alice he was looking for. At the same time, the optical camera also captured a young man with a beard, and Colonel Kim recognized the Asian man caught in the canopy boat, who was with the target at the time, which further confirmed that the blonde woman was Alice.

However, there is still the last Hellfire missile left on the Predator drone, and if it is launched to attack the woman in the woods, the remaining hours can only watch the target run away, because the next Predator drone will not arrive at the scene until three hours later, and the special detachment is still climbing the mountain in the crater, and it will not be able to catch up in a short time, so Colonel Kim canceled the attack in time. From this point of view, Wang Xiaoyu, a science and engineering man, is still relatively reliable in his inference about the source and range of the Predator drone.

Sergeant Benjamin flew the drone towards the hole in the rock wall, where there was a tall pine tree that was easily recognizable. He first saw a Chinese man hurrying away from under the tree and running into the cave. This situation surprised him, he didn't expect that there were still people hiding here. However, Colonel King asked to focus on the cave, but also to check the pine trees at the entrance of the cave, he controlled the drone and flew straight towards the pine tree, flying very slowly and steadily, focusing on the top of the pine tree, adjusting to the highest resolution, and taking the clearest picture.

Almost at the same time, in a certain war hall in the African theater of country M, Colonel King got this clear photo. He looked at the photograph and noticed that there was a particularly dense bunch of leaves near the treetops of the pine tree, and there was some metallic sheen in the gaps, so he enlarged the picture, revealing a half-saucer-shaped object. He recognized that it was the miniature radar rotating antenna on the newly developed individual air defense weapon, which had not yet been equipped with troops, and only the equipment that these CIA agents would carry when they were on special missions, appeared in this barren mountain and wilderness, and there was no doubt that it was brought out by the little girl of the foreign girl.

He immediately ordered the detachment, which was still searching the crater, to climb the mountain and go to the canyon. Look at the altitude line of this high mountain, 1945 meters, there is no road in the dense forest, and it will take two hours to climb the least, so I quickly gave another order to the drone.

So Sergeant Benjamin got an order: keep an eye on the hole in the rock wall, look for an opportunity, and be sure to kill the people inside!

He maneuvered the drone around the exit of the canyon and raised it up a hundred meters so that he had a larger radius to turn around the mouth of the rock wall instead of crossing the entire valley to make a U-turn. This is a valley, the mouth of the cave is only a few tens of meters high from the ground, the mouth of the mountain on the left and right forms a natural protection for the hole in the rock wall, and the airspace above a thousand meters can hardly find the window for missile launch.

It's just that in this way, it is only more than 100 meters away from the peaks on both sides of the canyon, and the sensor operator next to it raised objections, this distance is too little for a drone with a speed of 130 kilometers per hour, although there is computer-aided automatic operation, it is also significantly smaller than the provisions of the safety operation regulations.

Benjamin said to Colonel King through the headset: "Colonel, it is too dangerous to hover in the sloping valley, it is advisable to ascend to the top of the mountain to monitor the sky, we have enough resolution to see the people in the canyon clearly".

"No, that blind spot is too big, and you have almost no window to launch missiles. The target is a trained professional who is likely to escape".

"Okay" Benjamin had to bury his head in setting the parameters of automatic driving, after all, the computer is much more reliable than the manual operation.

Suddenly, the drone sounded the alarm, an unknown object approached at high speed, and it reached a very dangerous distance, and the sensor operator screamed in alarm: "Dodge, dodge!" ”

A cold sweat broke out on Sergeant Benjamin's forehead, what was coming? Coming from which direction? Such a high-resolution synthetic aperture radar did not show it, front, back, left and right, including the camera in the belly of the aircraft, and did not see anything coming, only the red light of the automatic obstacle avoidance sensor on the drone kept flashing, telling him which direction to dodge? Fortunately, Benjamin is well-trained, and he knows that this drone is designed for ground reconnaissance, and the main instruments are aimed at the ground, and the top of the back of the aircraft is its blind spot. Since it is impossible for a drone with a speed of only two or three hundred kilometers per hour to participate in air combat, this blind spot is not a big deal in peacetime, but the unknown object that is attacking at this moment happens to appear above the blind spot.

After hesitation, the camera in front of the plane found a bunch of green objects rushing towards him, Benjamin screamed, and urgently hit the left full rudder, and the bundle of green objects grazed the right wing and fell down the canyon, which could be avoided. Benjamin's heart was pounding, and his hands holding the joystick were soaked with sweat and trembling slightly.

At this time, the camera and synthetic aperture radar under the belly of the aircraft simultaneously discovered the falling object below, which was a bowl-thick eucalyptus tree, three or four meters long, with mud on its roots, dragging the green leaves that were hunting, flying in the air like a javelin.

Benjamin, who had just been shocked into a cold sweat, was now confused again, what was the situation? Will trees fly in the air? Before he could figure it out, the piercing alarm sounded again, the red light of the automatic obstacle avoidance sensor flashed uncontrollably, Benjamin seemed to remember something, a stretch, the nose of the plane was raised, and almost at the same time, the camera and synthetic aperture radar found the incoming object in front of him, and it turned out to be another eucalyptus tree with leaves, whistling from the top of the mountain towards the drone.

"Shit!" Benjamin, who was in a panic, scolded a country, and urgently dodged with the right rudder, he has thousands of hours of experience in controlling drones, and he has not encountered such a bizarre thing when he flew from Iraq to Afghanistan, which is simply unnatural and unscientific. The situation was urgent, and he could only drive the plane to stay away from danger. In a flash, pushing the joystick to the top, the drone with excellent performance flew straight up at a close right angle.

The drone quickly climbed more than 500 meters, flew out of the canyon, flew over the top of the mountain, and then made a beautiful backward flip, around the top of the mountain where the branches flew out, he wanted to see how those small trees flew into the sky just now.

Suddenly, another eucalyptus tree flew up from the mountain not far away, with dirt and leaves, and swooped towards the drone, Benjamin had already taken precautions, and the drone flashed lightly to avoid it, this time he saw clearly, there was a huge black bear below, and under the huge nose was an ugly mouth, full of yellow teeth and drooling, that appearance was somewhat similar to King Kong in the movie, and he was pulling out the tree with a snort!

After a false alarm, Benjamin, who is full of environmental awareness, decides not to bother with the animal, and is ready to let the drone dive and scare it away. There was really no way, only the last missile, Colonel King said to leave it to the woman in the cave.

The drone turned around and came back, and Benjamin realized that something was wrong, why was the black bear still wearing clothes? Is it a circus?

"There's a little girl next to you," the sharp-eyed sensor operator spotted the problem.

But no, Benjamin also found this little girl, with four small pigtails on her head, pointing at the drone in her left hand and a stone in her right hand, blushing, stomping her feet and swearing.

These two people are Xiao Shancha and Fool, and my sister Azhu hid behind a rock and kept calling Yang Xue, but the drone didn't see her.

After the fool understood that Xiao Camellia was going to smash the big iron bird, he looked for stones everywhere to vent his anger for Xiao Camellia, but he couldn't find any stones around for a while, so he naturally remembered the wood that he was used to throwing. It's a pity that I didn't bring a knife when I went out, so I had to pull out the small eucalyptus trees next to me, and threw them at the drone like a javelin, and he could throw hundreds of pounds of wood down the mountain, not to mention this small tree, and waved it to the drone under the mountainside, the small eucalyptus tree was like a sharp javelin, and the leaves brought up the whirring wind, and swooped down to the drone hundreds of meters away from the mountain. Although it didn't hit, it scared Benjamin enough. Xiao Camellia couldn't throw it that far with little strength, and could only stomp his feet and scold there.

Benjamin didn't know this, thinking it was a black bear raised by the little girl's family. But why was the little girl hostile to herself? I can't figure it out, and I can't bear to do it to the little girl, what should I do? He hesitated for a moment.

In his hesitation, the Predator drone had already flown over the hill where the little girl was, deviated from the course, and flew towards the next steppe, and after a while, the sensor operator noticed the problem and asked, "Ben, where are you flying?" ”

When Benjamin heard this, he hurriedly checked the flight track on the screen to see his ground control station, the drone was walking along the channel he set, but the GPS running track next to it showed that the drone had left the canyon and was flying towards the prairie, what happened?

Benjamin immediately switched to manual operation and tried to turn the drone back, but the drone did not listen to him and went in the opposite direction.

Now he understands that someone has implemented electronic jamming and deceived the GPS positioning system of the drone, isn't Africa the least developed region in the world? Where do you get such high-end equipment and talents?

With a head full of questions, I cut off the GPS navigation, replaced it with manual operation, turned the drone around, and flew towards the canyon again.

At this time, Colonel King's voice came from the headphones: "There is a miniature radar antenna in the pine tree at the mouth of the cliff, she is emitting a false GPS signal, you are going to destroy it with manual video aiming".

Benjamin answered, "Yes."

When he maneuvered the drone to approach the top of the canyon, the drone seemed to have encountered an invisible barrier, turned a corner on the edge of the canyon, and flew out towards the grassland. But this time it was not flying straight, but to the south for a while, and to the north for a while, and the drone was like a drunk man who had drunk too much, snakeing in the sky. Benjamin has seen the circle, and now it's not GPS navigation, it's manual control, how can such an evil thing happen? Is the machine malfunctioning?

Benjamin didn't believe in this evil, tried to clench the joystick, and suddenly hit a left full rudder, and this time the drone obediently obeyed. But as soon as he let go, the drone staggered and danced again, and flew out for a few kilometers before returning to normal.

The sensor operator on the side had been observing Benjamin for a while, and seeing that he had been competing with the drone, he couldn't help but remind: "Ben, is the signal emitted by your drone's own positioning system turned off?" ”

"Does this matter? If it is turned off, the operation of various instruments will be affected, including our synthetic aperture radar, which may send the wrong message. Benjamin said puzzled.

"Of course it matters, manual control is manual command, for example, the drone is from point A to b, and ordinary GPS signal deception is to give a false point b coordinates, so that you can't fly to the real point b. But if the coordinates of its own GPS positioning are wrong, the drone can't tell whether it is at point a, how can it fly to point b? To put it simply, it doesn't know where it is, so it can't get where you want to go. ”

"Although what you said is rather awkward and not necessarily reliable, I decided to give it a try!" After Benjamin finished speaking, he turned off the drone's own positioning system, and three devices, including synthetic aperture radar, prompted an error, Benjamin simply stopped them, and sure enough, the drone was more obedient this time.

Well, as long as the missile can be launched, he is confident that he can blow up the pine trees at the entrance of the hole with the aim of the video. But then I remembered that there was only one missile left, and it blew up the pine tree, what about the people in the hole? I couldn't help but feel irritable in my heart.

After tossing for a long time, the Predator drone finally flew in the direction of the canyon.

The drone quickly flew over the canyon, and the pine trees at the entrance of the cliff were vivid, and in order to ensure a hit, it was necessary to reduce the altitude and adjust the angle, because there were cliffs and mountain beams in front of it. However, Benjamin thought that a little girl with a chimpanzee on the top of the mountain was interfering with the drone, and it would be bad if he accidentally hit it, so Benjamin decided to scare them away with a dive.

In the blink of an eye, the plane was at the top of the mountain, where the little girl was still screaming, and a black bear next to her was standing stupidly with a branch in her hand. Benjamin decided to swoop down and scare them away. Soon, the drone whizzed and swooped towards the top of the mountain.

At this time, the radar observer next to it reported: "A drone of unknown nationality is approaching, model WJ-600".

He felt a burst of annoyance for no reason, it was a damn WJ-600 again, and a damn unknown nationality, and everyone on the earth knew that it was a model of the Chinese people. If he had attacked the little girl, in less than an hour, he would have vouched for a video of "Army M attacking civilians for no reason" would appear on the Internet around the world. He had no choice but to pull up the fuselage and fly far over the little girl's head.

At the same time, he issued a warning: "The fighter plane of the M Army is on a mission, and the plane will identify itself and leave immediately."

The WJ-600 that flew leisurely shook its wings politely, but it didn't fly away. Instead, a message was sent: "This is not the airspace of country M, our side has the right to pass through innocently, please do not obstruct our freedom of navigation."

Benjamin felt a blockage in his heart, his country has been asking for freedom of navigation in the South China Sea all the time, but he didn't expect that today he was asked by others not to interfere with freedom of navigation, in fact, this is neither country M, nor is it a flower planter, everyone goes to a third party's house to ask for freedom of navigation, and no one can say anyone.

What made Benjamin feel depressed was that the WJ-600 said that it passed innocently, but instead of passing and flying away, it flew in circles over the Predator drone a few kilometers away. What kind of way did he pass? Benjamin really wanted to ask the other operator: "Is your language taught by the PE teacher?" Did you pass like that? ”

Colonel Kim really wants to shoot down this-stirring stick, but look at the map, this is not far from the Ethiopian border, their army is called the East African Liberation Army, the equipment and instructors are from China, if he dares to attack this WJ-600 drone, in the blink of an eye, there will be a crazy revenge of the angry swarm, and all of them are of unknown nationality, so that you can't find anyone if you want to take revenge. Even if you shoot down one or two as evidence, it's just a bunch of black uncles who can't communicate. I had to order the drone to ignore it and continue to reconnoiter and monitor the cave.
