A one-ton bomb fell from the sky, with a huge speed, extremely fierce.

"Bang!" The bomb hit the roof of the building. In an instant, the entire building trembled violently. The impact was so huge that the prefabricated concrete floor slab was smashed through directly.

Several people on the roof were hit by flying concrete pieces and fell down screaming. A soldier was hit by the fragments and took two steps back. He ended up rushing and fell directly from the rooftop, screaming in mid-air.

The bomb hit the top floor from the rooftop, and the remaining momentum continued to smash through the floor. On the lower floor, the delayed fuse was detonated.

"Boom!" The explosion sounded extremely loud. There were hundreds of kilograms of high-explosion explosives in a ton of bomb. This one could explode a giant battleship. Now, in the huge explosion, the top of the building was instantly shattered.

Just like the blasting when demolishing a building, the above floors collapsed in an explosion, and countless pieces were blown away. When they reached the air, they fell down again, and the distance could fall hundreds of meters away.

The German soldiers surrounded outside hid in the armored vehicles, looked at the scene ahead and discussed it.

It's too powerful.

However, after the explosion here, the second HS29 attack aircraft entered a dive state.

When the bombs of the third attack aircraft were blown up, the entire building disappeared, and even a large pit was blown up on the ground, and concrete fragments filled the surrounding area.

There is no living inside.

Those who are not killed by the current bomb will be killed, and those who are not killed will be killed will be killed. If they do not surrender to Germany, this is the end!

Without any resistance, Germany would not consume its precious soldiers here in vain. It would use absolute strength to crush the stubborn guys to deal with the stubborn guys!

Now it's just calling for bombers. After that, it will be easier to install other new German weapons, such as individual air incendiary bombs.

With the bombing of the Kalinin headquarters, even if the battle of Kalinin came to an end, the German army had knocked on the northern gate of Moscow.

"Comrade Stalin, Kalinin is lost." In the basement of the Kremlin, Stalin's face became even more gloomy as he listened to his subordinates' words.

Kalinin, the northern gate of Moscow, has now fallen into the hands of the Germans. The Germans can drive straight in and rush to Moscow.

Come on, Moscow is waiting for the German army. As long as they dare to come, they will be hit head-on!

"We must strengthen our defense, deploy tight lines of defense in Klin, and wait for the German attack," Zhukov said.

As Zhukov returned to Moscow, he continued to gain Stalin's trust, and because of his previous foresight, Zhukov had a great say.

He was planning and commanding the defense battle in Moscow.

They had no more troops and could only watch Kalinin's loss. At the same time, this was in line with Zhukov's idea, defending layer by layer, constantly consuming the strength of the Germans, and finally fighting a difficult offensive and defensive battle with the Germans under the city of Moscow.

They had no extra army to Kalinin. In their plan, all the cities on the periphery would eventually be lost. The army sent there would be destined to be the end.

"At the last moment, the Kalinin Front did not surrender, and they fought to the last moment." Stalin said: "They were all good. The commander of the Kalinin Front, Konev, Chief of Staff, and others all awarded them the title of Soviet hero."

In the Soviet Union, this was the most honorable title, even if it was a senior commander, it might not be obtained. Now, Stalin awarded these titles to these martyrs, commending their bravery and tenacity in this battle, and calling on the entire army to learn from them.

"The failure of the Kalinin Military Region this time is a big reason for the lack of air support." Zhukov continued to analyze: "We can already see that if there is no air force, our ground forces will be very passive. Now, we must find ways to increase our air force."

The situation was quite unfavorable for the Soviets. They now have enough tanks and aircraft, but they all lack fuel! Several actions by the Germans have caused the Soviets to suffer from the shortage of fuel.

Originally, it was entrusted to the United States, but the sea passage has been temporarily blocked, and Moscow has reached its most dangerous time.

"The Gromov Test Flight Institute is using alcohol instead of aviation gasoline on our fighter planes. I don't know how the experiment is going." An air force officer said.

The Soviets will not compromise, and the Soviets must continue to fight. Now, since there is a lack of fuel, we should think of other ways, such as using alcohol instead of gasoline, is an idea.

However, this thing is not easy to operate.

South of Moscow, 40 kilometers, near the banks of the Moscow River, a small town, Stahanovo.

This city is very young. It was founded in 935. The city's name is to commemorate the famous miner Alexey Stakhanov. If only this is mentioned, almost few people know it. However, in later generations, it was famous, but it was changed to another name.

Zhukovsky, in honor of Nikola Zhukovsky, a pioneer in Soviet aerodynamics and fluid dynamics, the city was renamed in 947 and became the center of the Soviet aviation industry.

Here are three higher education institutions, Gromov Flight Research Institute, Central Air Fluid Dynamics Research Institute and Seplus International School of Management, which are the Soviet "city of science and technology" and "center of aviation industry".

Among them, Gromov Test Flight Academy was born on the eve of the outbreak of the Patriotic War. Just at the beginning of this year, the Academy was established according to the orders of the Central Committee of the Communist Party of the Soviet Union and the People's Committee of the Soviet Union.

The design of the aircraft has already had a unified process, among which flight testing is the most important, and test flight is not suitable for various design bureaus, but it is best to be in a unified professional place. This is the original purpose of the Test Flight Academy to develop and test new aircraft for the booming Soviet aviation industry and cultivate sufficient senior pilots.

Soviet hero, legendary test pilot, air force Lieutenant General Mikhail Mikhail Mikhail Gromov was appointed as the first dean of the test flight academy

However, as soon as the academy was established, the Soviets faced the invasion of Germany. Therefore, as soon as the test flight test institute was established, most of the experts and equipment had to be transferred to Kazan and Siberia east of the Urals. The test flight field of the academy became the base of the 45th Soviet long-range aviation division.

Now, the latest test flight is still underway in the test flight field, replacing gasoline with alcohol.
