For rockets, the most important thing is the engine, and this set of rocket engines, which has penetrated Goddard's countless sweat, is now fully mature.

When the ignition command was executed, the dimethylhydrazine and nitric acid sprayed into the combustion chamber quickly completed the combustion, and the blazing flames erupted from the nozzle at the tail.

The entire body of the projectile also began to vibrate, as if it couldn't hide its excitement.

"Increase the power."

This is not the launch vehicle of later generations, a little fire, it jumped out, and now it has just been ignited, the engine has been preheated, and it has not yet entered the best state.

Two seconds later, the flame in the tail has changed from orange to yellow and white, and the fuel inside is burning at an accelerated pace, and at this time, the thrust of the rocket's engine has reached 8 tons.

But it still can't fly, because the entire rocket weighs nearly 13 tons.

After another second, the engine with full thrust finally gathered enough strength, and at this time, this rocket, which looked like a big radish on the outside, finally began to rise!

When it first left, it was still very slow, but as it gradually ascended, its speed began to increase, and when it rose for 41 seconds, it reached 2 kilometers per second; After 54 seconds, the fuel has completely burned and the engine has stopped according to the program.

Of course, at this time, it is no longer visible on the ground, it has already flown to an altitude of tens of kilometers!

At this time, it has entered a normal ballistic trajectory, relying entirely on the inertial gyroscope inside the missile and the preset program to fly, and its target is the British air base opposite!

A fighter plane, it is impossible to fly in the sky all the time, it needs to return, refuel, hang up bombs, and at the same time, the exhausted pilots also need to rest.

If you look at it from the sky, it is quite easy to distinguish the Spitfire, just look at the wings, the end of the wing of the Spitfire is rounded, and until now, only the Spitfire is like this.

"Squeak." A Spitfire, skillfully aligning the runway, landed, and in the middle of the runway, it had already stopped.

The cockpit canopy opened, and a British pilot with a grim face stepped down.

Douglas Bader, the British Air Force pilot who gained the most in this sortie, this time, he hit a total of three German BF109 fighters, but only one was hit by him and smoked, and the remaining two were only damaged.

The way he walked was a little odd, and those who knew him well knew how determined and brave he was.

Bader joined the Royal Air Force as a cadet in 1930 and a year and a half later lost both legs in a flight accident.

Normally, such an outcome can only be disabled and retired, but with his perseverance, he learned to use prosthetics and even play golf.

In particular, last year, when the threat of war was looming, he persuaded the Royal Air Force to recall him, and he quickly learned all the skills of piloting a Spitfire, becoming one of the best pilots, and his commanders were amazed by his agility.

This air battle showed his combat ability, and people like him were born to belong to the blue sky.

However, he was distressed.

After landing, his plane was quickly hung up for the next takeoff, and he returned to the pilot's preparation room, where the meal had already been delivered, and they needed to eat, replenish their strength, and wait for the next sortie.

At this time, many people can't come back.

When he walked in, there was a heated discussion going on inside.

"The fighters of the Germans are completely suppressed by us in terms of performance, and we are simply going to die." Said one of the pilots.

As the pilots of the proud British Empire, they were not afraid of death, however, they were afraid that their death would be meaningless!

Now that's the case, in the case of the performance of the fighters being worse than the opponent's, their sorties are almost meaningless.

"Yes, even if we bite the Germans, they will throw us off with a negative G flight, and when we turn one hundred and eighty degrees and are ready to chase after us, it will be long gone." Said another pilot.

In the past, I didn't fight the Germans, and I didn't know how terrible the Germans were, but now, when I really fought with the Germans, I realized how terrible the Germans were!

Their fighters, almost without any weaknesses!

"Guys, technical problems, we can report to Super Marin, but right now, we have no choice." Bader spoke: "Our mission is to seize air supremacy, that is, to destroy the fighters of the Luftwaffe on the opposite side, and we must complete our own mission!" ”

"Now, let me summarize how we can turn the tide and turn the defence into the offensive when we are outfit." Bader continued.

Today, he tried his best to have a record of three planes, and he needs to tell his friends about his valuable experience so that he can avoid more losses.

However, he did not say it, and just as he said this, a sharp air defense siren sounded throughout the air base.

Damn, it's the Germans!

The Germans will not watch the British Air Force dispatch, so the British side has been guarding against a possible sneak attack by the Luftwaffe, and now, the other side is really coming!

Grabbing his flying cap, Bader ran outside, not looking at the prosthetic leg he was fitting, he had been using the prosthetic leg for several years, and he was proficient in various sports.

Of course, he did not run in the direction of the bomb shelter, but to the airfield, and as a pilot, the sound of this air defense siren, and at the same time his battle horn, took off urgently to meet the enemy!

However, he still did not run to his plane, and as he rushed out of the pilot's cabin, he looked up and looked south, where he should be able to see the blackened planes.

But no.

He didn't see the bombers, fighters of the Germans, what he saw, was a completely different kind of flying object.

At this time, it is descending at a tremendous speed, so to speak, faster than all flying objects, like a meteorite in outer space, it is definitely supersonic and even several times the speed of sound!

Now, as the other party was rapidly falling, with the pilot's eyesight, Bader could catch the target, which he could see clearly, and it was like a big turnip.

As it fell almost vertically from the sky, the big radish rapidly enlarged in Bed's pupils, and at this moment, Bed's mind was already occupied by shock.

What secret weapon of the Germans is this?
