Woohoo

"Head, the drone is online, and it will arrive at the battlefield in 2 minutes. At the same time, one person here can handle it, and Longhair is rushing over to meet you, and will be there in about half an hour. ”

Wang Jun nodded, "Pay attention to safety." ”

After speaking, Wang Jun beckoned to the big head, "The big head comes over and takes a hand"

Hearing this, the big head drilled into the narrow nose of the machine, and Wang Jun and Wang Jun worked together to move away from the deformed operating table, revealing a narrow passage.

This is a temporary service channel under the cabin for the crew to service the electronics in the nose section.

Wang Jun squatted down, took out a flashlight, put it in his mouth, took off the gun and got in.

The passage was filled with electrical boxes and some electronic boards that were still shining, and Wang Jun reached out to pull away a few wires in front of him, and found a long black sealed box in a pile of broken parts.

This is not the colloquially known 'black box', but an airborne flight data collector, the FDAU.

Wang Jun patted the ash on it, pulled out a cable from under the box and connected it to the GPS in his hand, the screen flashed slightly, and a set of flight data popped up.

Aircraft Climb - 15.43M......

LEFT FRONT STEERING -0.12M......

Reduced flight altitude - 0.32M......

Compared to the detailed flight data of the black box, the FDU can provide very little data, only the most basic operational data, left and right, and how long.

Wang Jun knew that the black box had been taken back by the local government, and he could only rely on this to briefly restore the flight trajectory of the plane.

Wang Jun didn't go out either, so he simply sat in the narrow maintenance aisle and took out the route map drawn by Long Hair and compared it.

The original trajectory of the plane was supposed to be near the West Haian Line in Malaysia all the way to the north, but the data recorded by the FDAU showed that the plane suddenly turned right at full speed after going straight for a period of time, while slowly reducing the flight altitude, and began to accelerate to land altitude after about 4 minutes of flight, and then a period of in-situ spiral flight, after which the plane recorded a pull-up operation, but the plane was too low to succeed, and then the plane crashed, and there was no record again.

Wang Jun compared the route map, and calculated that the plane would still maintain a normal speed after turning, and it should appear in four minutes near the mountain range called 'KhaoSaiThai', that is, 400 meters southwest of the wreckage of the plane, and then the plane landed sharply and circled in place to reduce altitude, all the time above the accident area. After that, the plane stopped circling in a straight line and made an emergency landing diagonally to the northeast and crashed in the current place, at which point the pilot tried to pull up the fuselage, but it was too late.

Why did the pilot try to pull up the plane after a series of strange tasks? Didn't he do it himself? Or was the pilot forced to do it?

Now there is no useful information about the wreckage of the plane, and the only thing that may be useful is the trajectory of the crash.

Gu Wangjun knew that the plane did not fall headlong, but was damaged and exploded after taxiing at an ultra-low altitude for several hundred meters, and the plane was blown up. In other words, there will be a lot of scraping and falling debris along the northwest direction of the wreckage, which may provide some clues.

Wang Jun stood up and jumped out of the maintenance passage, and said to the big head who was on guard on the side

"Let's go to the southwest and look around, maybe we can find the cause of the plane crash. ”

The big head nodded, and the two jumped off the nose to leave.

At this moment, Wang Jun noticed that the head of the plane behind him seemed to be a little strange.

The tip of the nose was originally a round protruding shape, but the bottom surface was seriously damaged due to severe friction, and the steel sheets and cables inside were exposed and no longer intact. However, the upper end of the front is not badly damaged, and the exterior paint and intact shell are still largely retained.

Because of this, Wang Jun noticed that there was an imperceptible circular dent on the top of the original intact, with a radius of about 15 cm and a depth of about 4 cm, as if it had hit something round. Thinking of what Chang Mao said before, 'The plane seems to have crashed into something', Wang Jun was suspicious, and stepped forward to observe it carefully.

The dent can be said to be smooth, so it can be judged that the hit object has a certain degree of hardness, so that it will not shatter immediately after impact, and the impact object is round, or oval, slightly larger than a basketball. Wang Jun reached out and wiped the dent and found that there were some dark black paint marks left on it, which should have been left by the impact.

Wang Jun frowned, could it be that the plane had an accident because of this impact?

It's hard to say right now. Only after examining the crash path to the southwest can we make a decision.

Without further ado, Wang Jun and Datou walked along the wreckage of the road to the southwest, and there were white debris of the plane and some pieces of luggage scattered everywhere, and it seemed that the plane was indeed taxiing past here.

After walking more than 100 meters, tumbling mud and broken branches appeared on the ground, indicating that the bottom of the plane had touched the ground from here, and then friction caused the fuel tank to explode.

Wang Jun looked down and touched the still warm soil, looked up and found nothing but debris.

The big head picked up a piece of the fragment of the outer surface of the airplane the size of a basin, and didn't see the reason, so he frowned and said

"Head, there's so little left here that I can't see any information. ”

Wang Jun sighed, "That's right, you can judge that the plane crashed from here, and nothing else can be explained." The plane over there was badly damaged, half of the tail was bare, the body was searched, and there were no clues in the nose......"

This is Wang Jun suddenly thinking of the dent in the nose of the plane, thinking if he can use it as a breakthrough?

Now Wang Jun can be sure that the plane hit something that caused the accident, and this impact object can be determined to be black, a sphere, is it possible that this thing has not been completely destroyed? It is still somewhere nearby?

Thinking of this, Wang Jun hurriedly contacted Tie Dan and asked the other party to use a drone to reconnoiter in the air to see if he could find this impactor

"Iron Egg, where is your drone?"

"The drone is over the wreckage of the plane right now, why didn't I see you, boss?"

Wang Jun looked at the GPS in his hand, and now they were 230 meters southwest of the wreckage

"Iron Egg, the drone flew 230M to the southwest, looking for a black spherical object within a radius of 500M with us as the center, probably a little larger than a basketball, which is likely to be related to this accident"

"Okay, uh, boss, is it metal? If it's not metal, it's probably harder to find...... Because my drone has a metal detection device, I can scan it directly if it is metal, and if it is not metal, I can only observe it with the naked eye."

Wang Jun thought about it for a while, judging from the impact dents, the texture of this impact object is hard, and it should be a good metal

"So, you look for metal over there, and I and Datou and Long Hair look for other materials. ”

"Okay"

After Wang Jun finished speaking, he gestured to the big head, and the two began to look for it nearby.

At the same time, Wang's military radio contacted Changmao, who had just arrived at the wreckage of the plane, and asked him to search for the ball in the southwest direction.

Not long after, a white drone stopped above Wang Jun, holding a spherical drone in its mechanical claws

"Boss, isn't this the thing?"

The sound of the iron egg came from the headset, Wang Jun looked up, stretched out his hand and compared, the size is the same, it is very likely to be this!

Tie Dan commanded the drone to put down the spherical drone, and Wang Jun stepped forward to observe it carefully.

The black spherical drone is roughly intact in appearance, but a finger-wide crack is split through the middle, revealing the mechanical part within, and it appears to have been violently impacted. Wang Jun lifted the drone and found that there were obvious scratches on the lower side of the drone, and a few places of paint had fallen off, which also coincided with the dents of the aircraft. Can't be wrong, this is the culprit that caused the plane to fall!

Wang Jun picked up the spherical drone and walked towards the wreckage of the plane, he still needed to compare it further to confirm, and at the same time, Wang Jun called Datou and Long Hair to stop the search and gather at the wreckage.

After a while, Wang Jun and the three of them put the drone on the dent of the nose and compared, just right, it was indeed this thing that hit the plane.

Long Hair couldn't believe it after learning about the situation from Wang Jun

"Can a plane crash if it hits a drone?"

Wang Jun shook his head

"That's true, but I don't think the plane fell directly because of that. FIRST OF ALL, THE DRONE'S IMPACT STRENGTH IS NOT ENOUGH, AND IT DOES NOT DAMAGE THE INSIDE OF THE AIRCRAFT'S HEAD, BUT ONLY LEAVES A DENT, INDICATING THAT THE RELATIVE SPEED OF ITS COLLISION WITH THE AIRCRAFT DOES NOT EXCEED 40KM/S, WHICH WILL NOT AFFECT THE AIRCRAFT. If, as you said, the plane was destroyed by a drone, it would have required at least 400 or more relative speeds. ”

"That is to say, at that time, the drone and the plane did not collide, but in the same direction, the plane was in front, the drone was behind, and the distance between the two became smaller and collided, is that so?"

The big head touched the bald head and analyzed

"That's right," Wang Jun nodded

"So there is a question of why the drone is here, how it is in front of the plane, and why the plane hits the drone and crashes again. ”

Wang Jun patted the shell of the drone, looked at the electronic equipment leaking inside, and said

"Iron Egg, put away the drone for the time being, the wreckage of the plane and we will be with us. ”

At present, Wang Jun and others can know so much, if they want to know more, they have to let the drone 'speak', and this kind of work is naturally indispensable to iron eggs.

Ten minutes later, Tie Dan hurriedly appeared in front of Wang Jun and asked panting

"What? It's my turn to torture the machine again?"

Wang Jun snorted at the drone

"Now, let's see what this thing is, and what the setting is in it."

Long Mao looked at it, and there was an excited expression on his face

"Well, wait a minute, I guess it's about half an hour"

Wang Jun nodded, sat on the ground and took out a cigarette and gave it to Long Hair, and then wanted to throw it to the big head and suddenly remembered that the big head didn't smoke, Wang Jun couldn't help laughing, sure enough, he hadn't seen him for a long time, and he almost forgot that the big head didn't smoke.
