Looking at the eyes of the slightly reproachful and questioning, Roland thought of it, but what this guy looked like when he was blaming him was also very cute... When he was in a good mood, he rarely called his brother, and he would hang his brother in front of outsiders or annoyed, so that people could not help but want to deliberately tease her idea.

Cough, no, now is not the time to think about the problem ... he coughed twice and pulled his thoughts back to the right track, "The plane is not yet fully stereotyped, so each part has to be made by Anna and Soroya." 」Now that the frontline war is on the right now, how much heavy their work is, you should know better than most people.Although I finished the design drawings very early on, I couldn't do it alone if I wanted to make it a reality."

With the extension of the railway, the interval between the Seagulls on the front line changed from the first one or two days to three or four days—not that Tilly and Wendy wanted to be lazy, but that a great deal of combat readiness was difficult to complete in a day, and there was no other way but to extend the stay.

As a pick-up person, Tily naturally knows how hard everyone is, many witches fall asleep directly in the seat as soon as they get on the plane, so the seagull has also replaced a more comfortable cushion and backrest.And defeating the devil and recapture the fertile plain is the most important goal at present, when it comes to this, her momentum suddenly reduced a few points, and the body on the desk also shrinks back, "I also want to start the test flight early, so that the empty knight can be useful ah..."

"Don't worry, in fact, the aircraft body has been basically completed, only some auxiliary parts are not installed, so you just have to be patient——"

“Wait,” Tiley interrupted, “it means that the ontology is...can fly without those parts, right?”

"Well," Roland realized at this point that he had missed his mouth, and that the Five Queens were no longer the layman who knew nothing about the plane, and it was not easy to be coaxed."... it's not that it's not a word, but it's fundamentally different from the seagull after all, and Wendy can't help correct the problem, once the operation is wrong..."

Speaking of which, he gradually closed his mouth.

Because Tiley’s radiant eyes had said it all.

He couldn’t refuse that look.

The nightinging-a-side had already made a soft laugh, and she seemed lately quite happy to see him speechless.

For a long time, Roland sighed, "Well, I'll inform the people at the airport to prepare."

“That’s right.”Tilly's raised eyebrows finally put down, and the corners of her mouth showed uncontrollable joy.

He mentioned the phone, "But remember, if there is an accident during the test flight, or if it loses control, you must give up the plane the first time, you understand?" 」

"Of course, because the plane can be built again, and pilots like me are precious," said Tilly with her arms, "you think so, right?"

...

No winter flight base.

At first, it was a simple cement clearing, nothing but two runways, but now it is a veritable flight training ground and the prototype of the Air Force Academy in the future.

Inside the walled test site, a silver-shiny plane was pushed out of the hangar by workers to the end of the runway.

Tiley took a deep breath, “That’s... specially built for me...”

"Well," Roland nodded, "the Unicorn."The main power is provided by a five-cylinder star piston engine, which theoretically allows the aircraft to travel at speeds of more than 150 kilometers per hour, and even the fastest beast cannot catch up with it.”

As the first autonomous powered vehicle of the era, it was very different in appearance from the Seagull glider – most obviously the huge head.In order to install the engine, the head can only abandon the aerodynamic appearance of the flow line, and make a less beautiful iron barrel, which looks like it has been flattened.

The second is the two-leaf propeller in front of the head, which is also a component not found on the Seagull - because it is the first practical piston engine, even with a lot of reference to the data, the finished product is quite conservative.In the case of little power, double wood pulp has been able to meet its requirements.

Finally, the fuselage, Unicorn because it is essentially a fighter, less than nine meters in length, is almost half of the seagull, and the fuselage does not need to wrap passengers, so it looks very small.However, the inside of the body is much more complex, in addition to manipulating the system, there are more fuel tanks, fuel pipes and other power components, and the second seat and fire system space are reserved.

"Unicorns... you get nice names sometimes."Tilly can't wait to go to the biplane, and quickly notice the strangeness in the cockpit, "is the missing auxiliary parts, originally settled here?" 」

The location of the dashboard, which should have been, is still two empty, and even if she had not seen the physical object, she could guess that it was not yet finished.

“Yes,” Roland nodded, “these parts are primarily designed to show speed and altitude, and are two of the most important parameters of flight.”Wendy used to control the attitude of the aircraft, and it didn't need to know that these things didn't matter, but if you really want to fly into the sky with the manipulator's own strength, you must always pay attention to the changes in these two parameters."

"Don't worry, I may not build a plane, but in terms of driving technology, it's definitely the first gray castle."She climbed into the plane with confidence and got into the pilot’s seat.

In theory, the Unicorn is only one more throttle valve than the seagull, and the other joysticks are even in the same position, and before that, Tily has also practiced many times on the simulation table, and should not make any mistakes.But after all, this is a completely new aircraft, the weight, flexibility, the corresponding speed are very different from the latter, the mechanical system has not been fully verified, what happened is not surprising.

Roland's concern also stems from this - if it crashes as soon as it takes off, even if Tilly has extraordinary operational ability, I am afraid she will not feel anything.At first, he wanted to build several more prototypes, so that she fell and became familiar with the new body.

But all this point, it is impossible to get each other back.

"Your Majesty, everything is ready."Report by the head of the hangar.

“Let’s start.”Roland turned away from the track.

“Yes!”

As the order was given, the two workers inserted the crank into the engine’s starter and rotated hard.

Obviously, the test is the latest sharp weapon of mankind, but this side is the same as the hand-held tractor when he was a child... Roland can't help but in the heart of the road, until the batch of equipment, he will get the battery and auxiliary motor out anyway.

"Bam, thump, thump-" When the piston gradually accelerated under the influence of external forces, a worker closed the pressure reducing valve, the oil vapor in the cylinder was instantly crushed, and the engine burst out with a few noisy blowns, and black smoke appeared.Soon the sound of the explosion was connected, and eventually became a deafening roar.

Two paddle leaves turned into a round of airy circular light and shadow, dragging the light body sliding up - just 30 seconds later, the Unicorn raised its head, vacated, rushed to the blue sky in the surprised eyes of all the people at the scene!
