The next day, Harry's squadron continued its sorties. However, their formation changed, and the two-plane formation was replaced by a larger four-plane formation. Moreover, this so-called four-plane formation is not really a four-plane formation in the strict sense, it should be said to be a 2+2 formation.

In this formation, two P-81s were in a lower and more forward position, and the other two aircraft followed behind and above. The vertical height difference between the two groups is about 1,500 meters, and the horizontal distance is about 1,500 meters. Such a distance is a little farther for an ordinary fighter, and it is likely that the aircraft in front will be in a bitter battle, while the support aircraft behind will not be able to arrive in time. However, considering the P-81's super acceleration ability and dive performance, the aircraft in the rear and above will rush to the battlefield much faster than ordinary aircraft, and this fighter is strong, as long as it is not hit by large-caliber anti-aircraft guns such as the 88 gun, it will generally not be solved by others. So this problem is not prominent. Increasing the distance has the benefit of increasing concealment. Let the fighters in the back row have more opportunities to be yellow sparrows.

The four planes departed two in front of the other. Soon, they caught up with the P-51 troops, who had set off a little earlier than them.

Now it's close to the goal. Harry began to lower the altitude. This is not to avoid the German radar, in fact, the level of the German radar is very average, for a target of the size of a bomber is quite reliable = one = this = read = novel xstxt spectrum, it is difficult to say about small targets such as fighters. Who can notice the small targets of 4 aircraft when the large fleet of escorts is all over the sky? Besides, the attitude of the Americans now is that they are not afraid of being discovered -- if they find out, they will send a plane out to fight me!

Over a German airfield, four BF-109s and four FW-190s are hovering nearby. These fighters are also divided into two altitude levels, with the BF-109 at a relatively higher altitude of 3,500 meters and the FW-190 at an altitude of about 3,000 meters.

The weather was fine on this day, but at an altitude of 3,000 meters, there were still some small clouds, scattered in the blue sky.

Harry and his formation began to approach the airfield from a height of 1,500 meters at a speed of 530 kilometers per hour. From a distance, two planes can be seen preparing to take off on the off-white runway. Harry didn't pounce right away, he began to look around the sky around him.

"The most important thing before launching an attack on the enemy is to be sure of your own safety. Strategically, the emphasis is on the destruction of the enemy, and only by destroying the enemy can we protect ourselves; But tactically, saving oneself is a priority, and only by preserving oneself can you effectively fight the enemy. This was the principle that Ron had set for the fighter unit in this war.

"Before going into battle, you must carefully observe the air situation and understand the situation of both the enemy and the enemy. Don't rush into battle! This is what the "Reverse Cross" teaches every fighter pilot. If a pilot is not habitual when walking, he will walk out of a few irregular s, and on average every 10 seconds without looking back, habitually observe the direction of 6 o'clock. Then he is certainly not trained by the "reverse cross".

This good habit, along with the P-81's well-seen cockpit, saved Harry, who looked back to see several FW-190s swooping down vertically above six o'clock in his own air. I guess these guys are planning to rush under their belly to give themselves a powerful one.

"Turn right!" Harry broke the radio silence and gave instructions to his wingman. At the same time, he rolls 90 degrees to the left and begins to circle to the left. The two P-81s immediately separated from the left and right and began to reverse their rotation.

"Discovered!" Seeing that the two strange-looking American planes in front of him suddenly made such a move, Captain Marcus, who had the idea of sneaking up to give them a moment, understood that there was no chance of a sneak attack.

But just because you can't sneak up doesn't mean you can't fight. Now two German fighters had an advantage both in energy and in angles. In terms of energy, they dived down from a height of 3000 meters, and relying on the dive, they gained a speed of almost 800 kilometers. On the point of view, they are now in the direction of 6 o'clock on American planes. So, Marcus thought, they had every chance of shooting down these two weird-looking American planes.

"Kerry, attack the one on the right!" Marcus gave the order to the other crew. At the same time, he and his wingman began to roll sharply to the left, trying to cut into the American's inner line.

The horizontal hovering of the FW-190 is quite average, far inferior to the Spitfire of the British, and not as good as almost any American fighter jet in service with the Allies other than the P-47, and certainly not as good as the Japanese Zero and Ki-43, and even inferior to the DF-109, which the Germans themselves called "flying slates". But the FW-190 has one thing that is extremely good, which makes the problem of bad hovering less serious, and that performance is rolling.

The FW-190 has the best roll of any World War II aircraft. The roll-over rate is amazing. This allows an FW-190 pilot who is following behind an enemy aircraft to always be able to complete the roll and enter the steering before he notices that the enemy is starting to roll and intends to turn. In this way, although the FW-190's circling ability is not good, it can take advantage of the time difference caused by the rapid roll, preemptively cut into the inner line of the enemy aircraft, and get a chance to fire. And with the powerful firepower of the FW-190 series aircraft, for some smaller targets, a single hit is enough to kill.

The wingman who followed Marcus was a little slower and didn't get a chance to fire, but Marcus still seized the opportunity to fire at the American fighter.

Shells whirred past Harry's cockpit, and Harry distinctly heard a few "poofs" - the sound of German 20mm guns hitting their own planes. Harry saw one shot hit the left wing, drilling a small hole in the wing, and a few more shots might have hit the fuselage. Fortunately, there were no problems with the handling of the plane.

"If only it was loaded with MK-108, a few hits would definitely kill this guy!" Marcus clearly saw that the American plane had been hit by several 20-mm shells, but it didn't even drop a bit of slag, and he couldn't help but think of the 30-mm MK-108 gun.

But Marcus also knew that the MK-108 was too slow to fire, coupled with a low muzzle velocity, and its ballistic performance was a mess, so it was not suitable for hitting targets like fighters at all. In fact, if I had used the MK-108 just now, I would probably not have been able to shoot a single shot. (So the FW-190 on air alert will not carry such a heavy, but inefficient thing when attacking fighters)

The FW-190's horizontal hovering ability was not enough for Marcus to bite the back of the Americans, and his current speed was too fast, which also led to a severe wing compression effect, making the already rotten hovering ability even worse. However, the FW-190 is never designed to compete with the enemy to push horizontally, and to fly it, you must stick to the vertical plane, and it is the most typical BZ fighter.

Marcus quickly pulled up the fighter, used his current high speed to jump to a high place, and then dived to attack the enemy plane. Now, as his FW-190 climbs at an almost vertical angle, he turns his head in an effort to make eye contact with his target.

It's just that the field of view of the FW-190 is really very problematic. Because the cockpit is deeply embedded in the fuselage, the aircraft has almost no rearview view (so little drag). The enemy plane, while diving downward, turned to his rear and quickly hid in his blind spot.

However, Marcus was not out of the question, he continued to pull the lever and began to fly upside down, so that he quickly found his target again with his head held high (at this time he was in a head-down state). So he continued to pull the joystick and swooped down towards his opponent.

Given the sturdiness of the enemy aircraft, Marcus wanted this shot to hit the opponent from the front of the flank, (which maximizes the lethality of the shells) rather than from the flank and rear, as he had just done. (Although this has a higher hit rate.) So he took a more aggressive approach to front-tracking, pointing the nose in front of the opponent's head, which is more aggressive, and certainly more unstable, and easier to get rid of than a rear pursuit that points the nose at the opponent's tail. He believed that if the enemy plane blindly ran away, with the excellent roll of the FW-190, he would definitely get a good chance to shoot again.

Harry, of course, saw the attack, and by this time he had reached a speed of around 680 km/h thanks to his dive and full horsepower. His wingman had also completed a circle at this time and turned behind him, but the two enemy planes that followed him temporarily lost their target and did not immediately dive down with Marcus.

The enemy plane that was watching rushed down, and he also pulled the lever and jumped up, forming an oblique head-to-head situation with the enemy plane. In this way, maybe Harry can get a chance to shoot at an angle.

The American 20 gun had a higher rate of fire and muzzle velocity, as well as a more reasonable type of projectile (but the warhead charge was smaller than the German one), so it also had a range far beyond the German 20 gun. Coupled with the fact that the P-81 was armed with as many as 6 of these guns, cross-fire was not a Meiji option for the Germans, who had an energy advantage. So Marcus quickly made a barrel roll, and both sides made a mistake and didn't get a chance to shoot.

Marcus pulled up the plane again and jumped upward, while the Harry formation, which was even faster, took advantage of the P-81's center of gravity to be further back and faster than the average plane, quickly completed a somersault and began to dive downward.

At this time, the rescuers on both sides arrived in unison.
