When Jin Erniang said this, she stopped again, sighed and said: "In all dynasties, there is no shortage of troops who can fight habitually; However, throughout the past 5,000 years, there has been no army that can compare with our people's soldiers, they are all iron-clad heroes, hot-blooded heroic sons and daughters, at the time of the survival of the nation, throwing their heads and spilling their blood, not afraid of sacrifice, one after another......"

Erniang said this, Jing Xiaolei also nodded like pounding garlic, fully approving.

Jin Erniang paused slightly, and suddenly said hatefully: "However, in our surroundings, it is not peaceful. There are many forces with ulterior motives that have been secretly preparing to move...... Even the big brother who helped us at the beginning showed the fangs of the beast at this time...... Transform into a blood-colored hairy bear...... It's hard...... It's too hard. ”

At this point, the whole world seemed to fall silent.

All that remained, the heartbeat of the two.

Jin Erniang's voice was very calm, but Jing Xiaolei could feel that there was extreme indignation in her calm voice.

Jing Xiaolei more or less knew some things from her parents and grandparents.

But for some complex and sensitive reasons, many young people living in modern times know very little about the truth.

Even some so-called historians don't know more than the average elder.

Jing Xiaolei thought for a moment: "We....... Let's skip those topics...... Tell me about work-related things. ”

Jin Erniang nodded, paused again, and then said: "Although we have done the strictest confidentiality measures, however, there are still a little signs that leaked out. At that time, we made the best camouflage net, covering the next door, and successfully escaped the tracking of the spy satellites, but did not escape the eyes of the 'blackbird'.

“blackbird？” Jing Xiaolei was taken aback, and couldn't help but think of the 'black technology' that transcended the times in the 60s of the last century

Even, some speculate that Blackbird technology may have originated from aliens.

Black丨Bird reconnaissance aircraft

That is, the SR-71, the Air Force of the M country, a high-altitude and ultra-high-speed strategic reconnaissance aircraft.

The flight altitude can reach 30,000 meters, the maximum speed is 3.5 times the speed of sound.

This is because the Blackbird flies higher and faster than the vast majority of existing fighter jets and anti-aircraft missiles, and it can be described as an artifact for detecting other countries' airspace as if it were entering a no-man's land.

The highest flight record set by the SR-71 was from New York to London - 1 hour and 54 minutes, and the top speed could reach 3,500 kilometers per hour.

The fuselage is made of titanium alloy structure, and the wings and other important parts are designed to adapt to thermal expansion.

It carries two crew members, the pilot and the system operator.

The cockpit is tandem, as the Blackbird flies at an altitude and speed beyond what the human body can bear.

Therefore, the two members wore not ordinary flight suits, but fully sealed spacesuits.

The Blackbird is equipped with the most advanced electron-optical reconnaissance equipment of our time.

Moreover, the reconnaissance cameras are all mounted on the guide rails, and the wheel axial movement is backward during photography, so that the camera is stationary relative to the ground.

Within one hour, it can complete an area of 32,400 square kilometers to carry out optical photographic reconnaissance missions.

Figuratively speaking, SR-71 only takes 19 minutes to take all high-resolution photos covering the entire Zisai region, six towns in the three northwestern provinces, including the Taklamakan Desert········
