"She's adjusting!" Conrad said, holding up the binoculars.

"Yes, of course!" Von Braun also raised his telescope and looked at it: "The distance we have flown has never exceeded one kilometer, and now it has been at least dozens of kilometers!" ”

"And I think it can keep flying!"

"Of course!" Von Braun said, "Because she's Hannah!" ”

"How long can the 'target plane' fly?" Qin Chuan asked.

"22 minutes!" Von Braun replied: "It can fly for 22 minutes on fuel, more than 200 kilometers, and the speed is similar to that of the British Spitfire......"

"But you didn't tell her that!"

"What?" Von Braun and Conrad couldn't help but look at Qin Chuan who was sitting in the passenger seat in surprise.

"Captain, are you sure we didn't tell her?" Conrad asked.

"Colonel!" Von Braun said, "I thought you told her!" ”

"I thought you told her, too!" Conrad replied angrily.

"Great!" Von Braun waved his hand, and then yelled at Werner, who was driving: "Boost your throttle, soldier, we're going to be left behind by her!" ”

"But it's an airplane...... Professor! Werner replied with a smirk: "Like you said, it's only a little bit faster than the Spitfire, do you want the jeep to catch the plane?" ”

Von Braun and Conrad were silent.

Werner and Qin Chuan glanced at each other and shook their heads secretly...... Scientists, they tend to focus too much on one thing and ignore other things, which makes them look like weirdos.

Soon the "target plane" disappeared from everyone's sight, and even with a telescope, there was no trace of it, and Conrad and von Braun were silent, as if blaming each other for missing the data, or perhaps guilty.

"We can think on the bright side!" Qin Chuan comforted them and said, "Professor, colonel, this is the first test flight, and Hannah may not be able to fly to the moment when the fuel runs out, so you missed the data and have no impact on the results!" ”

"Yes!" Von Braun nodded in agreement, but then he looked at his watch and said, "But fifteen minutes have passed now!" ”

Then the hearts of the two were lifted again.

As the minutes ticked by, the two looked at their watches from time to time and then looked back at a jeep following behind...... The jeep was in charge of Kuhn, who had communications equipment and was able to get in touch with the tracking points set up along the way.

Nineteen minutes later, Kuhn shouted ahead, "She's landed, but it didn't go well!" ”

"What's the situation? Be clear! Von Braun exclaimed.

"I don't know what's going on!" Kuhn replied: "She landed between the 16th and 17th tracking points, which is more than 160 kilometers from here. They saw the 'target plane' jumping on the ground a few times and were rushing to the 'target plane'! ”

"Is she safe?" Conrad asked.

"I don't know!" Kuhn spread his hands: "They haven't arrived yet!" ”

After ten minutes, I finally got the good news: "They found her, she is safe...... Just a little bit injured! ”

"Are you sure?"

"Yes!" Kuhn nodded: "I'm sure!" ”

Conrad and Braun let out a long sigh of relief and leaned back in their seats, looking like they were both in prostration.

After more than a while, several people met Hannah on the road, and of course, the "target plane" whose wings had been broken in half...... It's not for reuse, it's disposable, and even the engine is disposable, because it's cheap and prone to failure (valves are easy to burn through by a hot flame or have other problems due to high heat), and it's better to fix it than to make a new one.

The reason for recycling is due to the need for confidentiality.

Of course, no one cares about the "target plane" at this time.

Hannah had a blue nose and swollen face, and the corners of her mouth were still bloodshot, but she still smiled at everyone: "Hey, this test flight was a success, wasn't it?" ”

"Of course, Hannah!" Braun hugged her: "Thank God that you are safe!" ”

"Of course, nothing that flies in the sky can stump me!" Hannah replied proudly.

When he returned to the headquarters, Braun and several other researchers held a test flight summary meeting with Hannah.

In addition to the problem of data correction, the meeting mainly focused on test safety.

"Why didn't the 'target plane' land safely?" Braun asked, "I'm sorry, I didn't mean to question your technique, I wanted to improve......"

"I know, Braun!" Hannah laughed: "Don't explain so much, let's be professional!" ”

Hannah took a sip of water and replied, "My vision is not good, I can only observe the outside through the large glass holes on both sides of the cups, and I have to lie down to observe, although there is a meter data to cooperate, I still can't accurately judge my height when landing!" ”

Braun nodded in understanding, the reaction speed of the instrument was a little lagging, and the accuracy was far from the point where you could land smoothly just by looking at the instrument.

"We should improve the flying environment!" Qin Chuan said: "Otherwise, the next test flight will encounter similar dangers!" ”

"Captain, it's not that we don't change!" Conrad replied: "But if we change its shape, it means that its aerodynamic layout has also changed, and the data we get is not accurate." ”

"We thought about changing some areas of the front to clear tempered glass!" "But the front part is the navigation system, and if you do that, it will take a lot of time to make big changes!" Braun said. ”

"And the navigation system should be on the head!" Conrad added, "That would make it more sensitive!" ”

"I know!" Qin Chuan said: "But why don't you add something like a periscope to it, you can even install this periscope behind the curved arc of the head, it won't have much impact on the aerodynamic layout!" ”

The scientists couldn't help but be stunned.

Hannah couldn't help but laugh: "Great idea, Captain, you actually used the periscope of a tank on an airplane!" ”

Qin Chuan spread his hands and replied, "Who said that tank stuff can't be used on airplanes?" ”

Conrad held out his hand to Braun: "100 marks, Professor!" ”

"You've upped the ante?" Qin Chuan asked.

"Of course!" Conrad replied, "Because the professor wants to win it back with interest!" But he's clearly going to be disappointed! ”
