Plymouth.

After an intense day of construction, an air base next to the port in Plymouth has begun to take shape.

Around the base, there are more than 20 anti-aircraft guns, guarding the sky, and at the same time, the main body of the base is the runway in the middle.

With a road roller, the field is directly flattened, and then there is a special runway that is spliced together with steel plates.

How to quickly build an advance base under war conditions is a task for German technicians, and it takes a week to lay it with concrete, while the German army is advancing quite fast, and in a week, the runway that has just been built may be useless.

Therefore, after careful research, German technicians manufactured this kind of runway made of steel plates, which is called "PSP perforated steel plate runway".

This steel plate is not a single piece, but is made up of countless small pieces spliced together.

Each steel plate is about 6 mm thick. It is about 90 cm long and 60 cm wide, and it is rectangular in shape. The four sides of the rectangle have stamped hooks or holes, and the entire airport is connected to each other piece by piece.

In order to improve the strength of the steel plate, the steel plate is stamped out of the evenly distributed stiffeners and reinforcing holes, and the ribs are 1O mm high.

Therefore, the runway is not completely flat, and when the plane is taxiing on the runway, there will be bumps from time to time. However, at least the problem of presence and absence can be solved quickly!

After all, in order to prevent the British Air Force from taking off, they directly threw submunitions at their air bases, and Germany could not sacrifice sappers to clear mines, and it would become a forbidden area in the future.

The base here is being built rapidly, and at the same time, last night, the 3rd Combat Aviation Regiment of the German 27th Air Force was transferred here, and their planes are all F190, which is the flight unit of the entire Luftwaffe that has been fully equipped with F190, and the others are almost all mixed BF109 and F190.

At this time, the sky was just dawning, and the Luftwaffe, which had reached the British mainland, began to sortie.

Standing in front of his plane, Squadron Leader Heinz Barr, looking at the ground crew.

"Captain, the plane has been maintained, full of fuel, full of ammunition, ready to take off at any time." The ground crew on the side said.

The ground crew came by boat, and they bumped all the way at sea, and when they got here, they did not rest, and continued to fight, complete the maintenance of the aircraft, and now, each of them has red eyes.

"Good work." As he spoke, Heinz stepped into his cockpit and, with the help of ground crew, closed the hatch and started the engine.

The 1,800-horsepower high-thrust engine in front of it roared, and after checking various instrument data, Heinz released the brakes.

"3 squadron, let's take off, from today onwards, over Great Britain is our airspace!" Heinz shouted loudly over the radio.

The plane began to fly forward, and the wheels were constantly jolting on the steel runway, and as the speed increased, this bump became the bump of the entire aircraft, which was also the weakness of the steel runway, but fortunately, it was acceptable.

It's like sitting in a dinghy floating in the waves, well, it's very pleasant.

Relying on the powerful engine, the speed quickly picked up, and with a gentle pull rod, Heinz took off.

Behind him, one F190 after another, followed by the take-off, although there is no battle report yet, but it is obvious that the British will not be willing to lose, today, there will be a large-scale air battle on the British Island.

Although the F190 has a considerable range, it is still beneficial to deploy to a forward base, for example, taking off from here, directly over the UK, they can stay in the sky here for more than three hours!

The nearby British Air Base, which has been destroyed, will face the main pressure today from the 11th Sector in the east, that is, the main air defense of the London area.

The British, for sure, will pounce!

So, after takeoff, they headed northeast, patrolling at an altitude of five thousand meters, and when they flew over Exeter's head, a Junkers-290 bomber also happened to fly.

"Where is this going to be bombed?" Heinz said to himself, looking at the bomber.

In the flight troops, there is mutual envy.

The bomber unit, the envy of the fighter unit, is chic in combat, and the aircraft has good performance, and can fly out of all kinds of difficult maneuvers.

And the fighter unit also envied the leisureliness of the bombers, when they wore oxygen masks and cruised in the air at 5,000 meters, they were drinking drinks in the cockpit at an altitude of 8,000 meters.

Especially for bombers like the Junkers-290, the pressurized cockpit, no matter how high it flies, does not need to wear an oxygen mask, and the cockpit is quite wide. If on a long flight, they can even have a toilet to use.

Now, looking up at the bomber, Heinz is envious, before taking off, Heinz has already gone to the toilet, and during the three or four hour cruise in the sky, if something happens, he can only hold back.

Now, when he looked at the sky, he saw the bomber's belly bomb bay door open, and inside, something fell down one after another.

Not a bomb, that is, a leaflet?

Yes, just flyers!

The ink on it was still dry, and it was a hundred thousand leaflets that had been printed overnight, and now, these leaflets, falling from the sky, were falling over Exeter.

When they found the bomber overhead, Bernard and the others quickly ran out, and they looked at the altitude of each other's flights, and knew that they could not do anything.

It's too high. His own small arms could not shoot down the opponent, and then, in the sky, these leaflets fell like snowflakes, and gradually fell.

What is it?

Suddenly, a terrible thought popped into his head, and Bernard shouted loudly: "Quick, put on a gas mask!" ”

Any veteran who has experienced World War I will still remember the poison gas warfare, at that time, both the enemy and the enemy, there were huge casualties, and this Pandora's box, once opened, was simply a disaster for mankind.

Even Hitler was temporarily blinded in a gas war.

And this world war is very different from the last one, the combat style of positional warfare has disappeared, the Germans have pioneered a new tactic of blitzkrieg, and at the same time, poison gas has not been used again.

However, veterans will have intuition.

In the second half of last night, the Germans retreated, why didn't they fight? Are you waiting for a powerful weapon? For example, will this thing that fell from the sky today release poisonous gas? Or is it some other bacteriological weapon?

When the gas masks like pigs' noses were put on, the leaflets flew around them, and Bernard took one of the leaflets with his rubber-gloved hand and looked through the glass lens of the gas mask.

At this time, the water vapor was filled, and the lenses of the gas mask were already a little blurry, and he looked at the leaflet carefully, and suddenly, he gasped in shock, and the entire gas mask was pasted on his face. 7110
