The helicopter took off quickly in the once-in-a-lifetime window period, and soon reached the top of the dangerous rock, at this time the heavy snow was still falling, but the wind speed had decreased, Guan Hao They seized this opportunity to quickly drive the helicopter to the accident site, because of the lack of visibility, the helicopter slowly descended, Guan Hao asked Luke to open the hatch on the right side of the Black Hawk helicopter in the communicator, and put down the rescue soft ladder, when the helicopter descended to only about 30 meters from the bottom, the fuselage of the Black Hawk helicopter began to shake violently, The convective air mass at the bottom of the valley is too strong.

But the valley floor was so windy and foggy that there was nothing to see below.

Guan Hao signaled the instructor of the main pilot to reduce the altitude to 20 meters again, and the helicopter staggered and circled down, fortunately, the instructor was quite familiar with this position, and he could control it with his own memory and skills without navigation and mechanical assistance.

The Black Hawk helicopter descended to a height of twenty meters, and unfortunately, visibility was zero, but according to the positioning system of the wrecked helicopter, the helicopter was directly below the number three.

And the good news is that there was no second disaster for the helicopter: a fire after the crash, which is very good news for the rescue.

At a height of twenty meters, Guan Hao turned on the infrared thermal imaging detector equipped with the rescue helicopter, and as soon as it was turned on, two orange humanoid color blocks appeared on the 5-inch monitor, and it was obvious that there were two survivors.

Thermal imaging cameras work by using optoelectronic devices to detect and measure radiation and establish an interrelationship between radiation and surface temperature. All objects above absolute zero (-273°C) emit infrared radiation. The infrared thermal imaging camera uses the infrared detector and optical imaging objective lens to receive the infrared radiation energy distribution pattern of the measured target and reflect it on the photosensitive element of the infrared detector, so as to obtain an infrared thermal image, which corresponds to the thermal distribution field on the surface of the object. In layman's terms, a thermal imaging camera is to transform the invisible infrared energy emitted by an object into a visible thermal image. The different colors on the top of the thermal image represent the different temperatures of the object being measured. By viewing the thermal image, the overall temperature distribution of the measured target can be observed, and the heat of the target can be studied, so as to make a judgment on the next step.

According to the previous plan, if you want to rescue the injured, you need to send someone to the bottom of the valley to check the scene, and if there are survivors, you also need to put the rescue stretcher on the electric hinge to the ground, attach the survivors and quickly leave the danger zone. A stretcher can only lift one casualty at a time.

The limit height of the rescue soft ladder equipped with the Black Hawk helicopter is fifteen meters, and now the height of the helicopter is twenty meters, obviously people are not yet able to go to the ground, search for survivors, the helicopter still needs to continue to descend, at least three meters, now the climatic conditions at the bottom of the valley are very bad, it has exceeded the limit of the Black Hawk helicopter descent and hovering, the instructor tried his best to hold the joystick tightly with both hands to barely stabilize the helicopter, if it descends another three meters, it is too difficult, and according to the original plan, Both Guan Hao and Luke had to go down to the bottom of the valley to rescue the survivors, and one person could not complete the search and rescue work in a very short time.

At this time, the intercom sounded, and the early warning message of the personnel left behind in the rescue center: the dangerous rocks above the helicopter can withstand for up to five minutes, and then they will collapse, and then tens of millions of cubic meters of snow mixed with gravel will instantly pour down, and such a large force will be useless wherever it goes, which will be a devastating disaster.

There is less than five minutes left for Guan Hao to save them, Guan Hao and Luke have to go down to the bottom of the valley to find people, save people, Guan Hao and Luke plus two wounded, to evacuate safely, and at the same time to pull the helicopter up to the top of the dangerous rocks, and then use heavy weapons to fire, clean the diversion groove under the dangerous rocks and then clean up the dangerous rocks above, this kind of complex operation, only five minutes to complete, and do not allow any mistakes, to ensure that one step in place.

This is too difficult, not to mention that Guan Hao and Luke are still trainee flight engineers.

At a critical juncture, there is no choice, just do it!

The instructor descended to the limit height of only fifteen meters above the ground again, and the helicopter obviously began to shake more violently, and the rescue soft ladder and stretcher landed almost at the same time as Guan Hao, the soft ladder was the tool for Guan Hao to get up and down, and the stretcher was the rescue survivor.

has landed on the ground, without waiting for the captain's command, Guan Hao and Luke quickly slid down the soft ladder, and in less than 30 seconds, the two of them reached the ground with agility, with the help of the light of the strong flashlight, Guan Hao saw a scene that shocked his heart:

The entire helicopter fell heavily to the bottom, the tail of the helicopter was completely broken, and two of the four sets of propellers were broken.

Fortunately, the reinforced fuselage is basically intact, which is why there are survivors under such a strong fall, such bad weather and extremely low temperature conditions, it can be described as dripping into ice, which also allows the fuel leaking helicopter to survive the explosion.

Guan Hao and Luke didn't have time to think about it, Guan Tight searched for the survivors separately, and soon found that the weapon crew and co-pilot of the No. 2 machine still had vital signs, not enough for both of them to be seriously injured, neither of them had the ability to act independently, and they needed to be carried on a stretcher, among them, the co-pilot injured his head, and he was already bleeding all over the ground, and the person only had relatively weak breathing.

Guan Hao informed the center in the intercom that the survivors had been found, and after saying that, Guan Hao and Luke hurriedly carried the most seriously injured co-pilot onto the stretcher, time was urgent, there was only one stretcher, there was no time to repeat the mountain, Guan Hao decided to let Luke and the co-pilot go up with the stretcher first, and Guan Hao carried the relatively lightly injured weapon and grabbed the soft ladder to go up.

Guan Hao used a rescue rope to tie the weapon officer behind him, and then assisted Luke to pull the electric noose to the door of the Black Hawk with a stretcher, Luke quickly entered the cabin, and tried his best to pull the injured co-pilot into the cockpit, and at this time, Guan Hao was slowly climbing up with the wounded on his back, in this bad weather mixed with wind and snow, in the rickety world, Guan Hao Jian Ran brother climbed up. The helicopter did not wait for Guan Hao to come up and directly pulled up the height and flew above the dangerous rock, at this time the rescue had already happened for three minutes, and there were less than two minutes before the final collapse of the dangerous rock.

"Luke, as soon as the helicopter arrived, it opened fire, we didn't have time. Remember to hit the diversion groove first and then hit the dangerous rocks,"

"Understood!"

The helicopter was quickly pulled up, Guan Hao carried the injured survivor on his back and swayed with the wind on the soft ladder, at this time Luke had already pulled the grenade launcher and the insurance, with the help of the sight, a fire, "bang, boom", directly hit the target, the diversion groove disappeared instantly, between the electric light and flint, the drainage channel of the dangerous stone was successfully dredged.

"Hao, if you hold on a little longer, the diversion groove has been successfully dredged, now go and contact the dangerous rocks immediately."

After a burst of cheers, the instructor piloting the helicopter immediately pulled up the helicopter and flew above the dangerous rocks.

At this time, the emergency center's voice sounded in the microphone: "Guys, the sensors on the dangerous rocks have issued an early warning, the snow has broken through the critical value of bearing, and an avalanche will occur in ten seconds, the No. 3 machine evacuates quickly, evacuate quickly!" ”

"Rook, don't hesitate, shoot quickly, we still have a chance!" Guan Hao hurriedly said.

After speaking, with a loud noise, a white mist flashed in front of Guan Hao's eyes, and the shaking intensified, Guan Hao subconsciously grabbed the soft ladder, knowing whether it was a snowstorm or the snow caused by an avalanche, and he didn't know whether the loud noise was shot by Luke or caused by the collapse of dangerous rocks, in short, Guan Hao's brain was buzzing, and he couldn't see clearly in front of him, and he didn't know if Luke succeeded!

After a short circuit in the brain for a few seconds, it seemed like a century had passed to Guan Hao, and soon Guan Hao felt that the soft ladder was slowly being pulled up.

Slowly, Guan Hao heard the roar of the helicopter engine, and later, he heard the cheers coming from the microphone.
