Because there are no satellites or planes, the war concept of TEP civilization still generally stays in the era of giant ships and artillery. The more troops there are and the more powerful the artillery is, the higher the combat effectiveness of which side will be. Moreover, in order to overcome the air friction, the quality of the shell is extremely huge, which is completely an enlarged version of the shell once used by human beings.
In addition to giant ships and cannons, there is also a mode of war - that is, using air boats to transport missiles and bomb the ground. Which side's air boats can fly higher, then which side will be invincible.
"The war has never been far away..."
In the TV room, a streamlined huge airship arrived. O'Brien hurried to eat his breakfast and boarded the airship with the passengers.
Then, the air pressure pump sounded "suddenly" and inflated rapidly into the surrounding auxiliary air bag. With the increase of the volume of the auxiliary air bag, the empty boat took off very smoothly again.
This kind of empty boat, code named "Lin Qibai", can reach a maximum speed of 80 kilometers per hour. In the city, each public empty boat has its own route, and its rated speed can reach about 50 kilometers per hour.
Fortunately, the sites are straight, and there are no intermediate stations, so the speed is acceptable.
Because there is no way to build high-rise buildings and the population that can be accommodated per unit of land is not large, this civilized residence is like farmland, which is spread out neatly one by one, and the core area of the center must be the parking place for empty boats.
O'Brien's place of work is at the Meteorological Office of the observatory 50 kilometers away, which can be reached in just an hour.
When he came to the observatory, he found that the atmosphere inside was as usual. Most of his colleagues gathered together and chatted casually. The working day of the day had not officially begun.
The astronomical and meteorological observatory is mainly responsible for the exploration of the outer sky and meteorological monitoring.
Of course... Mainly the latter.
The requirements of air craft navigation system for climate are quite high. Whether it is windy weather or rainstorm weather, it may lead to traffic paralysis. This also requires that the meteorological observatory can more accurately predict the weather conditions and issue notices in time.
O'Brien's greatest wish is to launch a real meteorological satellite... There was such a project in the plan, which eventually died because of too difficult technology and too high capital requirements.
The whole country, even the manufacture of air vehicles is very difficult, not to mention launching rockets.
Therefore, the funds for star exploration are very, very little. Everyone thinks that if we consider this matter after the technology is developed in a few years, we may be able to save a lot of money?
Moreover, they have never used artificial satellites, and most tepp people don't think this kind of thing is very urgent. Can't they live well without satellites and accurately predict the weather? Only these meteorologists are eager for satellites, but the appeals of these experts are often of little use.
"After tomorrow, there will be a new tomorrow. The government will allocate millions of dollars a year to maintain a small astronomical telescope and satellite at most? At this rate of development, there will be no such thing in the next century! "
O'Brien sneered and complained about the shortsightedness of the politicians. Politicians cannot allocate money without visible interests.
A large number of scientists are sharpening their heads and thinking about how to make the empty boat fly higher. All the funds are invested in the empty boat. Since the failure of the last plan, the tepps have been too lazy to consider other aircraft that can produce qualitative change. Even many people directly believe that it is impossible to fly in the air.
"What's the weather like today?" Thinking like this, a colleague greeted him.
This is not a casual greeting, but their job.
Since there are no satellites, climate observation must be completed through the upper airship observatory. Radio communication and computer technology have already appeared on this planet.
O'Brien glanced at the data on the computer and thought back: "it shouldn't be a big problem... Of course, it's just my experience and judgment. Now our region is in a state of high pressure, there is a downdraft, and the probability of rainfall is rare... The air humidity is not high. "
"Another relaxing day." The colleague stretched lazily and didn't seem to wake up.
Just then, suddenly, a computer in the next room gave out a "didi" alarm.
"It seems that the radio interferometer has observed signals from outer space."
This kind of thing is not once or twice. Any neutron star, pulsar or even solar wind may have electromagnetic wave signals. The planet's atmosphere is thick enough that even the most violent solar wind has a negligible impact on the planet.
"I'll go and have a look. It's good to record it."
O'Brien trotted over and recorded the signals into the storage device. He suddenly found that these signals had a certain law, but they were more like the general telegraph code of TAPP civilization.
"Fortunately, I learned telegraph language..." he scratched his head and hit the keyboard, and the whole translation came out at once.
"Unknown civilization, Hello, we are human civilization from afar, coming with peace and goodwill."
"We abide by the principle of equality and free trade. Everything can be bought and sold, as long as you can pay the corresponding price..."
"We..."
When I saw this line of text, the colleagues who came to join the fun around laughed, "I bet some idle guy sent this message on the empty boat... Even the password is our telegraph password. Can we taps inadvertently conquer the whole universe?"
"What are you betting on? Lunch in a meal? I invited you. " O'Brien didn't care much either, and began to try to operate the space telescope: "but the direction of the radio wave does come from space."
"Is it true that their ship stays above the atmosphere? You're so boring. You have to look for something like this. Be careful to be scolded by the webmaster. " The colleague is still nagging next door, staring at the screen: "hey?!"
"This is... What?!"
His voice suddenly increased, almost from plain words to huge screams!
"Outside... Aliens!"
A large group of colleagues heard the scream and hurried over, thinking that something really happened.
A tiny shadow really appeared in the telescope!
It seems that... Staying at an altitude of 60000 kilometers, no empty boat can fly to an altitude of 60000 kilometers. There is no atmosphere at all.
It's incredible to fall into a dead silence in the air!
Aliens, aliens really appeared.
Everyone in TEP held his breath as if his brain had been shut down directly. Then after several seconds, the organic spirit point hurried to find the leader.
"Increase the resolution ten times!" The head of the weather station heard the news and hurried over. He said with a trembling tone.
O'Brien swallowed his saliva and didn't look very good.
The shadow on the screen gradually becomes clear.
You can see that there is not only one spaceship, but... 10!
A total of 10 spacecraft are moving above the atmosphere!
