Braun then accelerated the test flight, and two days later carried out a test flight, which no longer required human control for the first half of the 70 kilometers, until the 73 kilometers were slightly adjusted, and then again at the 200 kilometers.

Judging from this progress, Braun's statement that "only one or two test flights can be completed" is obviously an exaggeration, and the condition of the test flight must not be adjusted within at least 200 kilometers in order to be qualified, and the more the data needs to be adjusted later, the more refined the data, and sometimes a little amplitude needs to be repeatedly verified, otherwise, once it enters the mass production process and mass production is found to find the problem, it will be troublesome...... The "target machines" produced are all processed according to inaccurate data, and as a result, each one has problems.

Another feasible approach is to produce small batches and put them on the battlefield, find problems and improve them as they go, and then move on to mass production until they are satisfied with the performance.

In modern times, the United States has followed this procedure in the research and development of new equipment, which is why it will provide a certain advanced equipment to other countries for free...... For example, the "Stinger" missiles were put into the Afghan battlefield and handed over to the Afghan guerrillas before they were equipped.

This is not to say that the United States is selfless, but for two reasons:

The first is the needs of the Afghan battlefield.

The second is to treat the Afghan guerrillas as guinea pigs for experiments, discover in actual combat what shortcomings the "Stinger" has and what needs to be improved, and then produce and equip its own troops in large quantities after it is fully mature.

Obviously, the "target aircraft" may also take this road, not because it is perfect, but because the needs of the battlefield are too urgent.

The data were further revised, and another test flight was carried out two days later.

Now that the test flight has been carried out, Braun and Conrad are no longer as nervous as they were the first time.

And, of course, Hannah is relaxed.

Perhaps because of the experience gained from flying a few more times, or maybe the periscope worked, Hannah is now familiar with the "target".

For this, Hannah also expressed her gratitude to Qin Chuan: "The idea of a periscope is really great, Captain! It made the 'target plane' more like an airplane, which almost saved my life! ”

Qin Chuan just wanted to say that if Braun still wanted to gamble, could he also count Qin Chuan's share.

On this day's test flight, Qin Chuan took people to the desert early to set up tracking points...... Braun and Colonel Conrad are no longer out of the camp to track, which actually doesn't make much sense, the "target plane" flies 200 kilometers away in 22 minutes, and what a jeep with a speed of tens of kilometers per hour can chase, even if Hannah is in any danger, there is nothing that can be done.

Therefore, Braun and Colonel Conrad were responsible for the preparation of the "target aircraft" in the camp, and Qin Chuan was responsible for the tracking point outside the camp and the safety of Hannah.

Based on previous experience, Qinchuan mainly set the tracking point in the section of 100 kilometers to 250 kilometers.

This is determined by the range and failure rate of the "target aircraft", and there will be basically no problem for the first 100 kilometers, and there is often a danger of a forced landing after 100 kilometers.

"Report to all parts!" As usual, Qin Chuan did a tracking point inspection in the walkie-talkie.

"Number One is normal!"

"Number two is normal!"

It was broken on the third day.

"Three? Please answer the third received! Qin Chuan shouted in the microphone.

But there was still no response.

Qin Chuan opened the map and looked at it, and the third was a tracking point at 75 kilometers...... There are only three tracking points for the first hundred kilometers.

"Maybe it's a walkie-talkie malfunction!" Dominic said.

This kind of thing often happens, mainly because the desert is windy and sandy, and the tracking point has a great demand for walkie-talkies.

However, Qin Chuan was a little uneasy, he handed the microphone to Kuhn and ordered: "You continue to check, I'll go to the third point to have a look." ”

"Yes, Captain!"

Qin Chuan and his party of five drove a jeep to Point 3.

Dominic drove the jeep, Qin Chuan sat in the passenger seat, and three soldiers were crowded in the back row, one of whom was a communication soldier with a walkie-talkie on his back, and the other two were riflemen.

To be honest, it is still suitable for a submachine gunner like Dominic in a jeep, because the jeep space is relatively small, and the K98K has a length of one meter, which makes it very inconvenient in the car, and once you find an enemy, you can't even raise your gun to shoot, because your elbow or gun body will always be blocked by something and you can't aim at the enemy.

Dominic was much better, he leaned his submachine gun against the side of the car door and pressed it against his foot...... This is a common method used by a veteran, so that in the event of an attack, while opening the door with his left hand and jumping out of the car, he can carry a gun in his right hand and be ready for battle at the first time.

Qin Chuan didn't dare to do this, otherwise, the length of the rifle would be enough to jam Qin Chuan with his gun on his seat and wait for death. So he could only hold the rifle with his left hand and keep it in the air, like holding a flagpole without a flag.

Dominic seemed to see Qin Chuan's pain, and said with a smile while playing the steering wheel: "Captain, I think you should try MP40, I think you will like it!" ”

"Thank you!" Qin Chuan replied: "If I can, I'd rather try MG34!" ”

Dominic laughed.

After a while, Dominic asked again: "Captain, is this 'target plane' really worth our fight?" I mean, it's just a small plane, no one to operate it, and it's crashing into the enemy with a bomb......"

Dominic simulated an explosion in his mouth, and continued: "And then there is nothing, what is the difference between this and a shell?" ”

"The difference is that it can hit two hundred kilometers, but artillery shells cannot!"

"Why can't we sneak up on the enemy and run away with two shells?" Dominic still didn't understand: "I think it's much simpler, and those scientists are wasting their time!" ”

"No, Dominic!" Qin Chuan said: "This thing is much more important than you think. It can even be said that this thing will depend on this thing for wars in the future! ”

Dominic shrugged his shoulders and was noncommittal.

It is no wonder that Dominica does not believe that even in modern times, many countries have not yet recognized the value of missiles, until Argentina beat the British Navy with several "Exocet" missiles in the Battle of the Falklands, which made a blockbuster.

Qin Chuan looked at his watch, it was almost time for the "target plane" to be launched.

Sure enough, a few minutes later, the "target plane" flew towards the location of Qin Chuan and the others with a whistling sound.

What was surprising was that the roar of small-caliber anti-aircraft guns suddenly erupted in front of them, and black clouds flashed on the flight path of the "target plane" in an instant.
