Flying a fighter jet, maneuvering in constant overloads, challenging oneself in red and black vision, that is a whole body experience, and now, sitting in the midst of a blackbird and looking at space, is a different visual experience.

The starry sky is so vast, the earth is just an ordinary planet in the universe, and everyone is even more insignificant, and this feeling of space is realized at this time.

When you go into space, you will have a sense of nothingness and insignificance, and you will feel so empty all around, only yourself and the aircraft around you, some people will suffer from mental illness, and some people will fall in love with this feeling.

Nathan falls into the latter category.

Now, looking at the space outside, looking at the arc of the edge of the earth, Nathan couldn't help but say, "It's beautiful! ”

Hearing Nathan's words, Graham was relieved, this time with Nathan to experience flying, is to experience this feeling of going into space, in case Nathan has psychological problems, then can't let him touch the MiG-25, what if he falls?

Then, he heard Nathan continue, "It would be better to call it a blue bird!" ”

On the ground, the coating of the SR-71 is black, this coating is said to have a stealth effect, and the fuselage also has a planned reduction of the radar reflection cross-section, but unfortunately, when the Blackbird is flying at high speed, the huge infrared signature brought by high-speed friction, as well as the sound, and the resulting radar reflection, cause it to have no stealth function at all.

For example, the SR-71 is one of the largest targets on its own FAA's long-range radar, which can be tracked hundreds of kilometers away, that is, every time the Blackbird performs a mission, it is an insult to the target country, knowing that it is overhead, swaggering, but it is impossible to intercept.

At high temperatures, this black coating also changes color to the blue it is now. So, the blackbird also has a name, called the bluebird.

Pilots prefer to call Bluebirds to Blackbirds, and now, Nathan, a layman, has also uttered the word, which makes Graham agree with it even more.

The blue SR-71 looks even more beautiful, from the small cabin, you can only see the edge of one fuselage, which is also so likely, this feeling of flying at the edge of the atmosphere is also quite wonderful!

"Are we turning?" Nathan continued.

"Yes, we went around in a circle, just in time to return to the base, and today's experience flight is over." Graham said.

As the plane speeds up, the steering radius increases, and now Graham is steering slowly, a circle of 50 kilometres.

In this case, the inclination of the fuselage is very small, and the overload is also very small, but Nathan, who is sensitive to flight, actually experienced it, which has to make Graham admire, some people are born to fly.

"We're in Los Angeles airspace." Graham continued: "We need to cut into the public channel. ”

"No problem." Nathan looked at the knob in front of him, adjusted it a few times, and then, on the radio, there was a cacophony of sounds. It's pretty much the same, although it's a passenger this time, it's no problem to help out with small things once in a while.

In any country, there will be special air traffic control, especially in big cities, there will be a flight control center dedicated to guiding the airspace.

The Blackbird is not under the jurisdiction of the flight control center, however, the Blackbird will certainly be displayed on the other side's radar screen.

Graham's request to switch to a public channel is certainly useful, and in general, the airspace controlled by the other party may be used.

Now, before Graham could start calling, a voice came from inside.

"Cessna, ask for ground speed."

"Verse 90." The tower's answer was also brief. (1 knot is 1 nautical mile per hour, about 0.5 per second, 1 nautical mile is equal to 1.852 kilometers)

Ground speed is relative to the speed of the ground, generally speaking, the aircraft can know its own speed, this is with the help of the airspeed tube, it can only know the speed relative to the air, if the air is also flowing, there will be an error.

This is also a problem that has plagued pilots for many years, and it is not until the ground speed radar comes out that the ground speed can be accurately known and the error corrected, which is very useful for long-distance navigation.

However, Cessna is just a propeller civil aircraft, which is widely used in the United States, and this thing does not need to read the ground speed at all, and it must be that the pilot has nothing to tease the flight control center.

"Double-shot Beechcraft, request to read the ground speed." Then, another voice appeared.

"120 knots."

This twin-engine Beechcraft, also a propeller civil aircraft, is just twin-engine, faster, and this guy is definitely laughing at the first one.

"Dust 52, request to read out the ground speed." At that moment, a lazy voice was heard in the sky, mixed with the whistling of jet engines.

This voice was obviously even more proud, and sure enough, a voice came from the radio: "Ground speed 525 knots, dust." ”

This is certainly a jet fighter! This guy was also making fun of the guy in front of him, but he didn't know that he was about to be ridiculed.

Compared with speed, who can compare with the Blackbird reconnaissance aircraft?

Graham in front of him was itching in his heart, and just when he was hesitating whether to be chic, Nathan in the back had already pressed the intercom: "Flight Control Center, I'm Topol 20, request to read out the ground speed, over." ”

Nathan didn't speak much throughout the flight, but the headset was intact, so he knew that Graham's code name was Topol.

Now, Nathan's request was radioed, but, unlike just now, there was silence on the ground for almost five seconds: "Topol, my reading here is 1742 knots. ”

Haha, is it faster than the ground? Let you know what it means to have people outside the people, there is a sky outside the sky, and there are planes above your head!

There was complete silence on the radio, and the dust 52 who had just been about to laugh at the man must have looked as uncomfortable as if he had eaten.

A little later, Nathan heard Graham in front of him start calling, "Request for 60,000 feet of airspace access, done." ”

60,000 feet, which is about 18,000 meters, is the ceiling limit for most fighters, and civil aircraft are basically useless, most of them are around 10,000 meters.

Today's flight control center must be depressing.

"How are you going to climb to that height?"

Long-range radars, many of which are two-coordinate, do not have an altitude display. Therefore, the dispatcher of the flight control center thought that he had been teased.

Graham continued: "We don't plan to climb to that height. We're going to descend to that height. Complete. ”
