How to quickly blow up a car That’s what the movie teaches us. Shot him in the mailbox Hey. But the strange thing is During World War II Inside the fuel tank of a U.S. B7 bomber The German fighters went in. 11 shells flew back unharmed What’s going on? Are movies all fake?

30 July 1943 United States Army Air Corps 186 a large formation of b7 bombers Under the escort of 123 p47 Thunder Fighters attacked the German city of Kassel One of the bombers was a B7 G Number four two bars 29896 Nickname tender leo The plane belongs to the British Golden Bolton

379th Bombardment Brigade 527th Bombardment Squadron He’s on his way back repeatedly hit by gunfire from German fighter jets Of course, he is not a vegetarian Especially his tail gunner The Chinese name is Michael Arros. It shot down three German planes And one of the two machine guns was damaged.

In the case of another boat being stuck Arous managed to recover a second jammed machine gun And after the injury and the oxygen supply was cut off? Still continue to shoot So as to save his teammates and the plane Due to the outstanding performance in this mission

Arous was awarded the Distinguished Flying Cross You think that’s the end of the story? When everyone thinks that there is only one hero here The mechanic on the ground discovered another secret When this B7 returns to base The mechanic was surprised to find

The fuel tank of the bomber has been covered by a 20mm shell completely penetrated and the shell was left inside the plane But it didn’t explode Er… This is a miracle for explosive ordnance. But on this B7 This miracle has changed 11 times in a row. A total of 11 explosive shells

Quietly left in the mailbox So these shells were then sent to the military factory for processing. When they are opened Everyone dropped their chins. Because it’s in here If it’s empty, there’s no explosives at all. Except for one that was stuffed inside. a carefully rolled paper tube

It has a sentence written in Czech. After the translation is as follows This is all we can do for you now The answer is revealed This must have been taken prisoner by a German Jack Prisoner wrote it down It was he who sabotaged these aerial shells During World War II.

Germany will force countless enslaved and conquered people produce weapons for them Thus using these weapons to attack those who try to liberate them The most heroic thing they could do Is it not to destroy the production of these weapons? To know In these concentration camp factories People’s actions are subject to every moment.

Close and brutal surveillance Needless to say Once the vandalism is discovered The Czech worker will be executed immediately. So there are two heroes behind this blg survival And until today The identity of this second hero remains a mystery Look at the model of this helicopter

There is a high probability that he will think that he is a children’s toy There should be no difference with my two toys. But it’s actually true Hughes x 16 September h171952 First flight It has been tested for 3 years. A total of 33 takeoffs

Stay in the air for up to ten hours And it is with him Only then did the famous h64 Apache come into being. So today we’re going to talk about his story. Well, uh, when you first saw this helicopter What will you notice? Ah, first of all

Is that the huge rotor with the extremely incongruous proportions? Yeah, until now That pair of rotors still holds the world record. up to 40 m diameter This means that the length of one of its suspenseful It’s almost 20 meters. It’s basically the length of two 55-seat buses.

You can imagine this picture to mend your brain. Anyway, it’s very exaggerated Another obvious feature It’s the four landing gears that hate higher than the sky. They dragged the entire body of the x h17 up high Well, obviously, it’s just to leave the suspended part out. Use it for other purposes? Yes

That’s the whole purpose of designing and building x h17. It’s a so-called crane The purpose is to quickly transfer military materials. January 1946 The United States Army Air Corps issued a tender They want to get a Capable of lifting 4536kg payload The fastest can fly 105km Can hover at 915 meters per hour

Can cover a radius of 160km A heavy helicopter that can last for 30 minutes. And this helicopter has to be easily dismantled. to fit on a standard trailer Transport everywhere. All right, everyone’s thinking about it. think that such a request It seems that only radical and risky solutions can win.

For example, with the rotor of a Big Mac And change the traditional scheme of driving it from the middle axis. Instead, it uses wingtip jets to propel it into rotation. Er… The wheel of death in Britain that we talked about yesterday Do you have the same effect? So look at this photo.

The jagged shape on the wingtip is the location of the spout. And in this photo, though it’s black and white. But we can still see the rotation. The four obvious bright spots on one room They’re just a nozzle that’s spraying paint out. Initially, the contract was handed over to the Kellett Rotorcraft Company.

And the design scheme has been basically completed The middle also experienced several rounds of adjustment Let’s say it would have been just pushed into the middle of the blade. After compression, the temperature is not high air cold cycle hair. It was changed to later blow the hot air from the turbine into it.

Inject fuel again in a room Thermal cycling schemes for eruptions after causing them to ignite Tripled the power. More than that. But when the prototype of this helicopter is actually built, what is it? Kellett lost money Oh, is such a good thing going to miscarry? Hey, is the air force worried too

So it was set up with no helicopter development experience at that time. Alas But there are other Hughes aircraft companies Sitting with Kellett Say Why don’t you come and be the catcher Well, Hughes just didn’t hesitate at all. I agreed on the spot. and directly counted the $250000

What about all of Kellett’s designs and early model installations? I ‘ve received all of them. Er, this suckers seem to be very straightforward. Hey, what a suckers. This is the super bottom Hughes would have wanted to enter the helicopter field. But suffer from inexperience Hey, that’s good.

250000 you can get a ticket to the industry. It can’t be cheaper. So a lot of Kellett senior engineers I strongly oppose this deal. They know what’s going on in Hughes’s head. Of course, it was called x217 at the beginning. Now it’s called xx 17 Modification of drawings

It is true that there is no perfunctory ah It’s a serious patchwork of things. The prototype was sent out. The two-seater cockpit comes from pseudo-section cg Yao 5 Military gliders can be maneuvered What about the single-wheel nose landing gear? The b25 Mitchell bomber from North American Aviation

The rear two-wheel main landing gear is from the Douglas c54 Air Overlord Company Can hold 2407l fuel tank Also borrowed. Even the use has been changed. It originally belonged to a Boeing B29 Superfortress. It was used to hold a bomb Good power There are two general electrical appliances. improved j35 turbojet engine

To provide compression from the intermediate compressor stage The air is sent into the hub of the propeller. Then through the pipe into the tip of each blade Four intermittent combustion agents Where to add fuel and burn When the rotor turns at the normal speed of 88 revolutions per minute

This dual-hair configuration will provide x h17 The equivalent of 3480 horsepower Not only can they themselves can also be additional Something weighing up to 4665 kilos has been brought to the sky. The load index has exceeded the initial requirements of the military. ah, not bad But ah it’s a huge noise

Many reporters invited to watch its first flight said It sounds like it’s firing Even if you are ten kilometers away Also can’t avoid such noise actually The residents around the Hughes laboratory have been complaining about him. Second, its fuel consumption is extremely high Extremely low efficiency The maximum range is only 64km.

It’s just a fraction of the bid. Seriously unqualified The third suspense has a very short life. Because it’s pulling and pulling And space. Spitfire again So that he soon reached the limit of fatigue. Belongs to a kind of consumable goods Alas, it is estimated that the cost of using it is not low.

So in the intermittent test for several years When the rotor reaches the replacement deadline for the first time Just stop the whole project. Tell the case The military can spend money on smaller ones. Cheaper helicopters. And Hughes, ah, he didn’t suffer any losses. He’s now one of the big helicopter manufacturers.

Take out that epoch-making helicopter from him. h64 Apache There’s less than 20 years left. The story of X17 is over. But everyone is satisfied with the end. 23 November 1944. What about a B7 Flying Fortress bomber? He landed inside a British air base in Belgium. But the rescuers waited for 20 minutes.

But no one came out of it. Finally. The base commander, Major John Crisp, is losing patience. After he came forward and tossed They opened it and climbed in alone. But what unfolded before his eyes was empty. No one in the cabin There’s no one in the cockpit No one in the pilot cabin

There’s no one in the radio barn either. No one everywhere It’s like they ‘ve disappeared. But this heavy bomber, which weighs about 25 tons, is indeed Just after the successful crash landing here So what the hell is going on here I’m an encyclopedia rocket book

Today we’re going to talk about what happened in World War II. Quite a machine gun with absolutely real ghost bomber incidents Then tell the story at the beginning Major Crisp, when I first saw this Must be very blindfolded Because before he came in He was sure he could save a few living people.

And the probability is that there are more living people. Because when it was discovered that this b7 was rushing towards the base. He noticed that three of the four engines were still working. There’s no obvious damage on the fuselage. The landing gear has also been lowered. Even after a heavy touchdown

The propeller and a piece of the wing have been blown out. But the fuselage remains intact Even the three engines that were working properly. Also have not stopped meaning So everyone must still be inside waiting for rescue. But by this time his back was starting to get cold.

Why is there no one anywhere? Was there no one on this plane from the beginning? Well, but what about the next series of evidence he found It directly negates the idea. Let’s follow him and see First he found 12 neatly arranged

At first glance, I knew it was a parachute bag preparing for skydiving. They all remain unopened. Apparently, if someone parachuted Then he must have nothing on his back Then he saw some half-eaten chocolate Pick it up and smell it, yeah quite fresh Then he got into the pilot cabin. After a careful search

He made two more important discoveries. One is the Sperry headband sight that has been stripped of its camouflage. This is a sight that predates Norton The latter was explained in detail in my previous video. Very interesting I suggest you must go and see it later. Due to the high degree of confidentiality

So this kind of targeting zone will only be used during bombing missions. will be put into the plane And it must not be used for camouflage until the bomb is dropped. In case of an unfortunate crash The cover of the sight was lifted by the enemy. So once uncovered

That means the crew is ready to drop a bomb. The other is on the side. The code book on the navigator’s workbench First he was taken with a pen Marked next to today’s date and task code Secondly, in the last line of the blank page Apparently someone wrote in a panic.A bad flag.

Heavy anti-aircraft fire So, put it all together This evidence restores such a vague fact. It’s still on the B17. is a member of the organic group They were on a bombing mission But it was hit by heavy anti-aircraft fire. Under the shelling The plane must have had some fatal malfunction.

Caused the crew to choose to abandon the plane and parachute to escape. But such an explanation Even Major Crisp couldn’t convince himself. Because the contradiction is quite obvious Before the forced landing The b7 he observed was not damaged. Obviously, it does not meet the opportunity conditions. And the other is

If you want an opportunity You should at least have parachutes on your back. How can you just jump out? That’s not logical So after this matter attracted attention from all sides from top to bottom The military began sending special investigation teams Go to Belgium to learn the truth

The name Ghost Fortress is starting to appear on the headlines. People prefer to talk about the mysterious forces behind him Can’t do it He is indeed too mysterious Even the beginning of the investigation is still contributing to such a mystery. They found out This blg has no name. According to tradition?

Each sign should have its own unique name. Er… Or nicknames Like the famous Memphis girl Hell’s Kitchen Royal flush, et cetera, et cetera And then? Will give them a big picture on the head of the plane. And this plane has nothing. Investigators could only find a string of production serial numbers. Er…

Strange, isn’t it? But it’s good. With the help of this code Investigators have finally found the unit to which this marker belongs. 91st Bomber Brigade 324th Bomber Squadron Commanded by Lieutenant Harold de Bolt So the question now is Is Lieutenant De Bolt still alive? He’s not only alive.

He’s still alive with all eight of his subordinates. After the successful skydiving They landed in a park on the outskirts of Brussels. With the help of a local man. After hiding in an abandoned schoolhouse for a few days He was rescued by the British. It looks like

The truth that investigators were waiting for seems to have finally arrived. So let’s take a look at Lieutenant DeBolt’s testimony. That morning. They were ordered to take part in a campaign against Germany. The bombing mission at the Mersebo refinery Mel Cyber is an important industrial city in Germany.

It was seen as the only hope left in Germany at the time. So heavily guarded More than 400 anti-aircraft guns Twice as much as the capital Berlin. Ah, it’s a nightmare for Allied pilots. Unlike the British army. The U.S. military also especially likes to launch bombing on white days.

Although a good view helps one’s own accurate dropping But at the same time, let the enemy fire It’s easier to find targets in the air. Alas, it is estimated that they feel that their labels are fine So not too afraid Lieutenant DeBolt The command is such a strong title

He just transferred from the 401st Combat Squadron a few days ago So this sign doesn’t have a name of its own. Also seems not so strange After flying with the big army for a while They are close to the destination And began to climb to the height of 8500 hundred meters.

But at this very moment De Bolt suddenly found that his plane was so powerful. One of the engines seems to have some sort of malfunction So he had to leave the formation to find a solution on his own. Well, you want This time over enemy positions

Is it obvious that flying low alone becomes a sitting target? So the anti-aircraft fire came quickly. One of them went straight into the ammo bay. But I can’t tell why it’s so good. The shells did not explode. It just damaged the bomb dropping mechanism. Lieutenant De Bolt wiped a cold sweat

And turned back to look at their own situation Outside, anti-aircraft fire continues to explode on the side. Who knows if the next second will rush directly into the cockpit? Smoke billows from the damaged bomb bay. Soon the whole plane was covered. Mechanical failure also prevented the bomb from being released.

And the reason is unknown at first The engine that stopped is completely finished. Only three left Seems to continue to work hard So he made an important decision right away. Mission Canceled Return to Base Started to turn around and fly back towards England But the plane’s power continues to be lost.

Another engine is starting to smoke Their height is also falling. Lieutenant DeBolt gave the order. Abandon all unnecessary things in the cabin Hoping to be able to struggle to fly across the Channel But let him down The second engine quickly went from smoke to fire. Finally shut down

They obviously can’t fly any further. The only option left is to abandon the plane and skydive. According to DeBolt First he let the crew members jump out one by one. Finally, after setting the aircraft to autopilot mode Jump out of He was absolutely unexpected Just to get yourself out of the autopilot mode

Even the plane itself was saved. Yes, this B7 after maintenance Actually on the battlefield again And De Bolt and his eight comrades continued to fight. To the end of the war Alas, but is this the end of the story? No. Because the mystery surrounding him Still no reasonable explanation Let’s summarize

Major Crisp’s statement from the ground And from the air Lieutenant De Bolt’s statement There are a lot of conflicting places. The first is in the air. Claims they ‘ve been hit by heavy anti-aircraft fire But the people on the ground said the plane they saw was intact.

All the subsequent damage actually came from the impact of the crash. So they suffered heavy shelling Is there such a thing? Second, how many engines are broken? The sound in the air broke the folding supports on the two floors. At least three more are working. Even after the crash landing stopped

The three engines haven’t stopped yet. Third ah The air says they jumped with a parachute. So rescued And what you see on the ground is 12 complete. No open parachute The sea is not on the plane Fourth autopilot, right? But an automatic landing has never happened before. It’s incredible to think about it.

So the whole thing seems to be confusing. Is it really being manipulated by some mysterious force? Well, officials don’t like this attitude very much. They prefer to use amazing coincidences and extreme luck. to sum up the matter And successfully for Yichang is a contradiction in terms. Found a reasonable explanation

Er, let’s listen to it personnel at the first belgian base due to lack of knowledge of blg So it’s very likely that he was damaged in the first place. Mistakenly thought it was his decay after the crash landing. Second, after the basic opportunity The engine that stopped inexplicably at first. And inexplicably restored

Third ah It can be that this tag has a lot of spare parachute bags. It could also be Colonel Crisp. All I saw was the empty parachute packaging. He didn’t open it to check inside Fourth B 17 Flying Fortress It was the world’s first all-metal four-round heavy bomber.

It is known for its firmness. It often happens after severe damage. It’s still possible to land safely. So this unmanned landing, although incredible But what happened to B17 is still understandable. How about Do you think these explanations can erase the doubt in your mind? All right. No matter can ah

He’s one of the most mysterious events that ever happened in World War II. Glad to be able to share with you I’m Uncle Rocket Focus on me Tell you a different science story.
