Konstant was not wrong about this.

The current internal combustion engine is also fuel combustion, but it is in the cylinder, the cylinder block is iron, and there is a heat dissipation device outside, and the piston is iron or aluminum, at the same time, among the four strokes, only one is burning, and the other three are all without high temperature and high pressure environment, so the piston can also dissipate heat in the back and forth.

However, the newly researched jet is different, the rearmost turbine blades are always in high temperatures, and if there is no suitable high-temperature material, this turbine blade will quickly burn out, and its life will be quite short.

As a good technician, he was now acutely aware that the material was the first problem they would encounter, and that the design of the turbine was not so important in comparison.

It was because he couldn't find the right material that Constant never made progress, just as Edison had to test so many materials in order to invent the electric light in history, and he also needed to find the right material.

And even if a prototype of the Germans was obtained?

Even if the elements in the other party's turbine blades are analyzed by the most advanced means, and the production process is not known, it is still impossible to produce, and there is no other role except to provide one's own ideas.

When Hoover heard this, he was immediately disappointed.

And he could also think that when Mr. President heard the news, he would be even more disappointed, unable to develop a jet quickly, then the United States would not be able to fight in the next big war!

And now, he didn't know that the fighter plane that had been obtained was burning into a pile of scrap metal, and the American intelligence officers present were also blown up by 20mm cannon bullets, and their bodies became pieces of minced meat, and Germany's retaliation came very violently.

Only the medical van remained.

"Quick, quick, quick!" In the hospital van, a leading captain kept urging: "They don't dare to attack us, as long as we get to Frobischebe in front, we will be safe." ”

Baffin Island is also sparsely populated, and they chose a simulated airport, even more inland, and now they have to travel more than 100 kilometers to get there.

When the time comes, as long as they enter the city, they can get rid of the plane overhead, and they can easily take a boat and leave here.

The car was moving forward on the ice field, although the speed had reached its maximum, but the captain was still uneasy, with the airfield bombed and the plane destroyed, the prisoner in their hands was already the final result.

Several military doctors examined the captive's body, and it was fine, but he had fainted, and he should wake up in a few hours.

Finally, the city was gradually seen in front of me, and at the same time, it was going to be dark outside, and as winter approached, the night here would get longer and longer, and as long as it was dark, the other party would not be able to see it!

At this moment, suddenly, there was a loud rumbling sound in the distance, looking to the side, the side window had been covered with a thick layer of frost, he held a card, scraped the frost on it, and now he saw clearly, it was two strangely shaped planes, with a large turntable at the top, which was whining and turning, very similar to Leonardo da Vinci's helicopter.

As if to confirm his suspicions, the plane actually hovered, and then, slowly, descended, just ahead of their path, less than a meter above the ground, and came to a steady stop.

A rope hung down from above, and a well-armed warrior slipped smoothly from it.

"Quick, get around!" In an instant, the captain knew that there was a big trouble, and it must be the Germans who came to intercept their own pilot and save them!

The driver was also ruthless, gritted his teeth, turned the steering wheel, and the car left the rough road and headed to the side.

The wheels were in the snow, and he pressed the accelerator to the end, and the car struggled forward in the puffs of black smoke, and at the same time, those who got off the helicopter formed a line of skirmishers, rushing towards them at a rapid pace!

After the other party got down, he put down the sled from his back, and he actually skied over!

The German special forces are so adaptable, when they train in Finland, they are proficient in skiing, if you go directly, you can walk in a deep snow nest, the speed is very slow, and if you ski, you will walk like flying.

Now, Morris was at the front, paddling through the snow as if he were flying on the snow, towards the white medical van.

"Hurry, hurry!" The captain shouted.

The driver's accelerator was already in the end, and he was also in a hurry, and at this moment, suddenly, there was a resonant sound in the car, which was particularly loud, and at the same time, the car did not move.

Not good, the wheels are trapped!

One wheel was idling, digging through the snow nest, getting bigger and bigger, sinking the wheel deep in it, and the driver drove forward, no, and then reversed.

Just when I started reversing, there were already figures outside.

"Get out of the car, get out of the car now!" Morris raised the automatic rifle in his hand and shouted at the people inside.

It's just too easy, it doesn't feel like a special operations mission at all, it's just a training exercise.

The door of the car opened, and inside, the Americans came out one by one with their hands raised.

Morris didn't pay attention to them, and when all the people inside came out, the two fighters went in, carried the pilot Ted inside, out, and headed for the helicopter.

Soon, the helicopter took off again, rolling up the surrounding snowflakes for less than ten minutes, cleanly, leaving only these Americans in the snow, staring at the helicopter.

After tossing and turning for half a month, it ended up like this, most of the people involved in the operation died, and nothing was found, only the wreckage of a plane.

The roar in the sky disappeared, and Baffin Island entered darkness and calm again, and in the rear, hearing the news, Donovan could no longer contain his rage.

When Donovan finished venting, the adjutant on the side said cautiously: "After all, we still got the wreckage, and the wreckage is also of research significance to us, and also, of the two sortie planes, only one of them arrived at our camouflaged base, and the other one, where did it go?" ”

This matter is not over yet, after all, there is another plane, which is attracted away from their base, and at the same time, the navigation on the return is interfered with, maybe it is lost?

Yes, if you find this plane, won't you still be able to complete the mission?
