Quit your whining, Karen. When this channel originally started, there wasn't even a narrator, you had to READ all the information, so you couldn't even have it on as background education while you were doing chores and such.
I read an article from a retired Spanish military aeronautical engineer where he aknoweldged that at least in 1951 a He.70 was still flying. It was in Tetouan, then Spanish Morocco, where they had a handful of Civil War relics, including a lone He.70 that was deemed as air unworthy. A new colonel arrived to command the Tetouan base in 1950, and when he found out that there was a He.70 he ordered to restore the plane to flying condition. He had flown the model in the Civil War and required to use it as his personal liaison plane. The aforementioned engineer was dispatched from Seville to have a look and he found out that the plane was in quite good condition except for the wheel brakes, that were elastic tubes that operated under compressed air action and they were long gone and replaced by some rigid tubes that did not work at all. Then he started to look for spares in all Spanish bases and he found out that at León there were original brake spares, so they could fix the plane and put to fly again. When the engineer was moved to another destination in 1951-1952 the He.70 was still flying regularly, but he did not know when it was the last time.
@@thelostcosmonaut5555 It was a magazine, Revista Española de Historia Militar, vol.11, cover history "Bombas sobre Ferrol". I checked at the editor's webpage (Alcañiz-Fresno) and it apparently is still in stock. The magazine is focused on the Spanish military history, so unsurprisingly the Spanish Civil War is the largest source of information. It has another article on the He.70, but during its service with the Kondor Legion.

@@vincedibona4687 It doesn't really flow with the topic of the video or the narration. I get it tho, sometimes picking the right track can be a chore and I certainly am not a musical expert.
I would like to leave a couple of comments. Elektron is flammable and easier to ignite if in sheet form, the Germans also used it for engine mounts as a pair of bulky forgings, one either side of the block, throughout WW2. As far as I know this was not a particular fire hazard. Westlands in the UK also used a single Electron forging in the Lysander for the horseshoe-shaped forging that made up the undercarriage legs and connected them to the fuselage. This was often the most salient surviving part from a crashed aircraft, apparently it too didn't burn often. Lysanders built in Canadas used s conventional structure for the undercarriage. The density of Elektron is about 1.8 g/cc while duraluminium is about 2.8 g/cc, Elektron is actually a trade name registered by a British company. The other fire hazard in the Blitz was the absence of self-sealing fuel tanks, I would list this as the main problem. BMW engines were nothing special. Reliable but high displacement engines run at low manifold pressures. They did not have reduction gears, hence the small relatively inefficient airscrew and the blunt nose. The first fighters in Luftwaffe service were Arado and Heinkel biplanes that used this engine, then it died out as it basically did not have development potential. BMW then concentrated on radial engines, they inherited from Siemens via Bramo the Bristol approach with the Jupiter, and from somewhere else licence production of American engines (Wright I think), this gave them their head start in the field. It may interest our readers to know that the prototypes for the Bf109, He112 and Ju87 first flew with British engines, the Rolls-Royce Kestrel, as the Jumo power plant destined for these aircraft was being slowly developed (carburettor feed, fuel injection came much later as did the DB engines). The Kestrel was a fully developed, totally reliable engine that had been in service for years, so it was hardly secret. Germany however, did not have any money, the result of war reparations and Weimar Republic management, so they did a barter deal. Germany would send a nice Blitz for Rolls Royce to play with, and RR would give them a handful of engines to test Hitler's new toys. RR was very happy with the deal because the Blitz, with its exquisite aerodynamic purity, was the perfect test bed for the new high-power fighter engines in development, allowing these to be tested at close to their envisaged service airspeeds. The cabin of the Blitz was also spacious enough to accommodate a couple of technicians and a pile of engine monitoring instruments. As nobody was going to shoot at it, the fact that it caught fire easily was not so much of a problem. There are some keyboard engineers out there that claim that the Blitz inspired the Spitfire. This is total rubbish, the design of the Spitfire had been finalised weeks before the Blitz arrived in the UK. The theoretical properties of an elliptical wing planform were well known in the aviation field since the end of WW1 and several manufactures made use of these qualities, so it was not unique or miraculous. The Blitz had a conventional multi-spar wing structure with a fairly thick profile, the Spitfire had a modified elliptical planform, a mono-spar wing making use of a leading edge torsion box and a very innovative laminated main spar, also the profile was much thinner. Mitsubishi's first monoplane fighter for the IJN also had an elliptical planform, and later the P-47 and Hawker Tempest also. Why didn't everybody use this if it's so good? Basically because of cost, every rib in an elliptical wing meets the span wise elements at a different angle, this requires multiple machining operations and extra care on assembly. The Spitfire's wing cost three times more man-hours to build than the Bf109's trapezoidal wing. It's a nice idea, and aesthetically very pleasing, but once you actually start building the things you realise what a burden it is.
@@phelmersaid701 I've no plan to do so, I will occasionally respond to other people's articles. Sometimes this causes heated discussions if what I say goes against someone's faith. It's important to keep an open mind and rely on fact-farming rather than heartfelt beliefs. I spotted (I did not waste time watching it) a video that said in the title that th Soviets loved the Sherman tank... I don't know where he got that one from, the Soviets rejected the Sherman that was being offered on Lend-Lease. This in turn caused problems because the US had been gearing up to produce thousands of the beasts. They then tried to politically bully the British to stop all tank manufacture (weird that one, the British after all invented the thing, but the US does this all the time, I suppose it's part of the Special Relationship) so that they could sell them more Shermans. They lost, the British continued to build tanks and rather better ones than the Sherman towards the end of WW2, the Centurion was the great success story of its generation. Summarising, there's a lot of misinformation out there and I think a lot of it comes from the gaming fraternity that relies on perceived qualities rather than verifiable facts. Also the re-enactment groups generate their own parallel universe, but that is more historical than technical. You can start by looking up a subject in Wikipedia, then cross over to other related articles. Check their sources, Wiki is fairly reliable on technical matters, less so on purely historical matters but look at he references.
Actually I was going to comment the same. However a “pronounce Heinkel” search produced ..HYN-KUHL. Apparently it is a name and is not pronounced as normal German words. So: Hinkel.
@@Ubique2927 You obviously know nothing about German pronunciation. It's my second language. The diphthong 'ei' is pronounced like the English word 'eye'. lancerevell5979 is exactly correct. If you have Google Translate, pull up German on the left side, type in Heinkel and click on the little speaker. You'll hear it spoken correctly. 'Hinkel' ist total falsch. The narrator just can't seem to be bothered with doing a simple bit of research. I hate to think how he would butcher names like Arado, Blohm und Voss, Bücker, Fieseler, Focke-Wulf, Gotha, Junkers and Siebel. About the only time you'll run into a difference in pronouncing 'ei' is with Dornier. Claude Dornier was from a German-French background. Thus I've heard both the German pronunciation of 'Dor-neer' and the French version, 'Dor-nee-ay'. Take your pick.
@@kevindolin4315 How about; Inga Andrea Köcker Elsterman von Elster. My ex wife’s name. And she pronounced it Hinkel. Because it is a family name pronounced how they pronounce it.
Rolls Royce obtained one, Messerschmitt's first 109 prototype was powered by a Rolls-Royce Kestrel VI. This engine was obtained by trading Rolls-Royce a Heinkel He 70 for use as a test platform. It was used to test Merlin, the irony associated with these events is breathtaking given subsequent events. Though the head of engine production for the ministry of aircraft production Major G P Bulman and the head of engine production of the RLM at the time were great friends. Wilhelm Schaaf left the RLM, to become Director in Chief for BMW.
Beyond the use of magnesium, the He70 also had issues with carbon monoxide poisoning, unprotected fuel tanks, and a lack of armor. The last two are attributable to its origin as a high-speed mailplane.
Actuallly, elliptical wings were a kind of Heinkel trademark (I.e. He.70, He.111 and He.112 to name a few). It is said that the He.70 had its share of influence on the Japanese dive bomber Aichi D3A "Val', but I never heard that it had on the Spitfire.
Journal of Aeronautical History Paper No. 2013/02 The Spitfire Wing Planform: A Suggestion J. A. D. Ackroyd Former Aerospace Division Manchester School of Engineering The Victoria University of Manchester. The paper discusses the reference of the HE 70 to the Spitfire, deals with the career of the Canadian-born aeronautical engineer, Beverley Shenstone who for a period worked in the German Aircraft industry.
@@diegoferreiro9478 thanks for that. I just looked up the Val and there is an elliptical similarity in certain images. The he70 had very impressive stats for a plane first flown in the early 30’s
The plane was a civilian light transport, and not a warplane. Armament, cameras, all kind of military equipments were imposed on the design. Thus the bad evaluation of the plane by the military. For instance, the project was improvised as a dive bomber, to compete with the purpose-made Ju87. The resulting He118 could not dive vertically, but only to a limit of 45 degrees, if my memory is not failing. Udet tried the vertical dive, finishing this in parachute. The plane was not meant to be a weapon at all. Anyway, the He111 bomber and He112 fighter were, and were sucessful airplanes. This connection could perhaps be more deeply explored in another video.
In his biography, Ernst Heinkel describes how the He-70 came to be. A new lucrative commercial aerial service appeared in the US for moving mail long distances quickly by air. Lufthansa wanted to start such a service in Europe and were considering buying American Lockheed aircraft which had pioneered the fast air mail service in America. Heinkel convinced Lufthansa's general manager to give him a chance to build a German mail aircraft with superior performance and the result was the He-70, designed by Siegfried and Walter Gunther. It lived up the Heinkel's boasts. A year or two later when the Nazi government decided to rapidly build up an air force, they sought military versions of the sleek, modern He-70, as they did the also did with the Ju-86 and Ju-52/3m and FW-200 Condor airliners, with limited success. AFAIK, the He-70 was never purpose designed as a military aircraft. No wonder Luftwaffe personnel were not impressed with it's 'poor military capabilities'. 03:11 "... the He-70s wings, crafted from spruce and plywood..." I believe the whole airframe was flush riveted metal. That was reputedly a point made by Beverley Shenstone, aerodynamicist at Supermarine when he examined one at Croydon Airport in the early 30s. Apparently he was impressed by the flush rivetting and the pure elliptical metal wings. He would later work on the Spitfire. I expect that archival footage is hard to come by but I wonder if it's possible to avoid bucketing the screen with an assortment of rapid cuts that are not directly relevant to the subject at hand? For example.. At 07:33 the topic is the He-70 in the Condor legion during the Spanish Civil war (1936-9). 07:40 Quick cut toFW-190A, which did not enter service until 1941-2 07:41 Quick cut to Bf-109F or G, not in service until 1941 07:42 Quick cut to Lockheed P-38 Lightning ! (Well I suppose 'Blitz' is German for 'Lightning' so...) 07:43 Another Bf-109F or G from the future 08:47 "... propelled by a one thousand one hundred and seventy five horsepower Daimler Benz DB-601A engine ..." Over the top of this narration is footage of a partially dismantled radial engine, not a DB-601, not even an inline engine. Great footage, but... 11:17 discussion of the He-70's commercial success over footage of a Junkers G-38 airliner Quentin Tarantino would be pleased with the fast cutting, but at times it can feel almost like a weird acid trip... To be fair Dark Skies this is a common issue with historical aviation documentaries on YT. It's not just this one. IMHO the He-70 was a largely forgotten but important milestone in 1930s aeronautical engineering. Thanks for this video.
I can confirm by the article that I mention in another comment that the He.70 had the wings made out of wood. One of the fears that they had is that the caseine glue that bonded the wooden parts could have crystalized, but upon examination by a mechanic with expertise on wooden structured aircraft the glue was in perfect condition.
Yeah a definite improvement from a few years ago, when he was literally throwing unrelated stock footage up that had nothing to do with the aircraft he was talking about, and the script was literally him reading Wikipedia....
@@eddiebruv No it was not. Beverley Shepstone had a say in it after touring the USA iT WAS PURELY A Brit design puleed from many sources What Supermarine tried to copy was the flush riveting of the Heinkel but did not have the up to date machines and had to make do with what they had.
@@jacktattis sorry bro, look back at british aircraft design, including the s5 and s6 by supermarine prior. They definitely took HEAVY inspiration from the he-70
@@cjones070 Shenstone said that he did not but he did say when he saw it at the Paris Air show that the plane was very close to perfect aerodynamically. Coincidence? maybe . However Heinkle never went on with the wing shape .
Propylen Glycol is a better compound for cooling liquids, it takes away more heat than ethylenglycol based anti-freeze and cooling liquids, propylengycol is not deadly toxic if ingested
I once made a Hungarian markings He 170 from a kit, so thanks for bringing that into the video. Yes, it looked impressive and modern enough, but there needs to be more for a front-line combat type. Noting that some have commented to that effect, the He 70 was featured in Heinz Nowarra's book on the He 111, in which it was unavoidable to have photos juxtaposed with each other of the He 70 and the Vickers Supermarine Spitfire to show the influence the former had on the latter's design. It was ironic, therefore, that the Spitfire was the nemesis of many a He 111 in the Battle of Britain. I do think that you need to tone the commentary down to increase your channel's credibility, however and the flexibly mounted defensive machine gun would have been an MG 15, not an MG 17.
I have come cross the statement that ethylenglykol allowed the use of smaller radiators, before. Though, an automobile engeneer told me that a water-ethylenglycole mix is not as efficent in transfering heat as pure water. Therefore, I wonder, what Is true.
You gotta convince me that a time traveller didnt put the locks back into the flight surfaces XD. Strategic bombing capability was missing during the battle of england.
It finally came to me why it looked a little weird.. the body looks like an upside down spitfire in a way. The plane looked fast just sitting there. You can see a lot of other planes( allies included) in the sleek lines and shapes. Too bad none exist today.
I found music appropriate..content direct and very informative. Great content folks. Why...just curious...after the Hindnburg disaster did the Germans make another aircraft from flammable $ hi+?!
The Germans were almost onto the right combination to produce a Mosquito type light bomber, using speed as it's defence against fighters. Throwing out the extra crewman and machinegun, I know it would have topped it's previous speed. Of course, once they discovered the damn thing liked to burn, it could only ever have been used for civilian purposes far from the front.
Wever was a strong advocate of strategic bombing and one of the few voices that recognized that the large distances in the inevitable conflict with Russia would require a long distance heavy bomber capable of bombing factories East of the Urals. Goering and others believed the war would be over quickly and a heavy bomber would only consume scare resources ( which was true) His loss really setback the program of being able to inflect damage to the industries that supplied the weaponry that the Germans would face on the battlefield in the East.
As with all German words containing the letters 'ei', the emphasis in pronunciation is on the second letter, the 'i' and not the 'e'. Heinkel is therefore pronounced as 'Hyn-Kul' and not 'Hen-Kul'.
Seems like the fellow in the back standing up to shoot or hanging out to hold a camera destroys the sleek designs. I'd hate to stand up into the slip stream. I wonder why the clever Germans didn't put the camera into the bottom of the plane?
A civilian passenger target for Polish anti aircraft guns before WWII. Served on the runs to and back from Estonia and other eastern Germanic interested.
Hungarian He-170 version was faster and generally better as well as used in WW2 - longer than stated here, for long and then short-range reconn. as well as close support! The He-112 had the same wingplan scaled down. And the Yanks used flammable magnesium in the B-24!
I can often spot a 'Dark Skies' clip when surfing through youtube just by the opening title : it's usually something slightly outrageous or annoyingly overstated. Possibly, having been interested in aviation for seventy or so years, I know too much. But ...... I avoid Dark Skies youtubes, they are ridiculous.
Absolutely clueless shambles of unrelated assorted video clips that contradict the shambolic commentary. E.G. commentary about the fitting of a V12 Mercedes DB601 engine. While showing a totally different radial engine being built.🤦

"... propelled by a one thousand one hundred and seventy five horsepower Daimler Benz DB-601A engine ..."
Over the top of this narration is footage of a partially dismantled radial engine, not a DB-601, not even an inline engine. Great footage, but...

discussion of the He-70's commercial success over footage of a Junkers G-38 airliner
Quentin Tarantino would be pleased with the fast cutting, but at times it can feel almost like a weird acid trip...
To be fair Dark Skies this is a common issue with historical aviation documentaries on YT. It's not just this one.
IMHO the He-70 was a largely forgotten but important milestone in 1930s aeronautical engineering. Thanks for this video.
I can confirm by the article that I mention in another comment that the He.70 had the wings made out of wood. One of the fears that they had is that the caseine glue that bonded the wooden parts could have crystalized, but upon examination by a mechanic with expertise on wooden structured aircraft the glue was in perfect condition.
You do understand the improper images and mispronunciations are on purpose to get more clicks and comments right?
Shepstone was impressed by the Riveting not the Wing Design they had used the elliptical design in 1929 Spec 20-28
Cant you people just WATCH..?
@@clarencearnold2137Probably not We all have our own barrow to push.
I love the b roll he finds, its stunning
Yeah a definite improvement from a few years ago, when he was literally throwing unrelated stock footage up that had nothing to do with the aircraft he was talking about, and the script was literally him reading Wikipedia....
Please lose the annoying background music.
The wings apart from the slight gull wing dip look very spitfite-esque ,maybe they should have developed this further than the 110
The Spitfire wing shape was actually developed from heinkel design.
@@eddiebruv No it was not. Beverley Shepstone had a say in it after touring the USA iT WAS PURELY A Brit design puleed from many sources What Supermarine tried to copy was the flush riveting of the Heinkel but did not have the up to date machines and had to make do with what they had.
@@jacktattis sorry bro, look back at british aircraft design, including the s5 and s6 by supermarine prior. They definitely took HEAVY inspiration from the he-70
@@jacktattis
Beverly SHENstone was a Canadian who worked in Germany before joining Supermarine
@@cjones070 Shenstone said that he did not but he did say when he saw it at the Paris Air show that the plane was very close to perfect aerodynamically. Coincidence? maybe . However Heinkle never went on with the wing shape .
Propylen Glycol is a better compound for cooling liquids, it takes away more heat than ethylenglycol based anti-freeze and cooling liquids, propylengycol is not deadly toxic if ingested
I once made a Hungarian markings He 170 from a kit, so thanks for bringing that into the video. Yes, it looked impressive and modern enough, but there needs to be more for a front-line combat type. Noting that some have commented to that effect, the He 70 was featured in Heinz Nowarra's book on the He 111, in which it was unavoidable to have photos juxtaposed with each other of the He 70 and the Vickers Supermarine Spitfire to show the influence the former had on the latter's design. It was ironic, therefore, that the Spitfire was the nemesis of many a He 111 in the Battle of Britain. I do think that you need to tone the commentary down to increase your channel's credibility, however and the flexibly mounted defensive machine gun would have been an MG 15, not an MG 17.

‘…light bombing missions…’ - the defenceless citizens of Guernica..
The background noise makes this one unwatchable. Im outta heeer
Rolls Royce purchased a Heinkel He70 in 1935
Nice find!
ALL 4 minutes of sleek, elliptical, amazing, envious and then SPEED 377 KPH = 234 MPH! 234! You have run out of planes to talk about.
I've always wondered how aircraft like this were developed at the same time as aerodynamic insanities like the Ju52
I agree with @jonhowe8768, no music
The British Spitfire used the same wing design.
I'm not sure that hanging out of the cockpit dangling a heavy camera, was the best way to go about taking pictures.
Music is overbearing.
@7:43 P38?
It reminds me of a faster, more manoeuvrable version of the Fairy Battle.
Woah 🤯 BIG BOSS
(*W-H-O-A)
Lose the annoying music!
Play the music louder 😂
@@unclecodyd_babyy4741 no, the opposite. 😂
Interesting attempt with the rock but that usually works best with a bassy voice over. Maybe fiddle with the audio settings befor trying it again.
The music is distracting and off-putting
That background music is really annoying. Prefer to watch with subtitles and no sound.
The flying torch....
Well, that was the HE 177 Greif, also known as the flying coffin
I have come cross the statement that ethylenglykol allowed the use of smaller radiators, before. Though, an automobile engeneer told me that a water-ethylenglycole mix is not as efficent in transfering heat as pure water. Therefore, I wonder, what Is true.
Interesting; well done. So much unrelated footage is a bit annoying, though.
If it is mysterious, who do we have so much information and film footage of it ?
Buzzwords generate clicks.
It looks like a Fairey Battle with the engine the wrong way up! ( and was probably just as useless!)
The audio is worthwhile, but the generic stock footage pushes me to listen to it in the background.
As soon as I saw that wing, I thought 'spitfire'
This music is so unfitting for literally every reason please don’t use it again ☺️
Is it just me, or does the head-on view of this plane look like it's wearing a pair of sunglasses? 🤓😎
is just you 😎
Looks like it had lots of elements of the supermarine sea plane from the Schneider trophy races.
isn't this the plane that was bought in 1936 by the British Air Ministry and Rolls Royce as a test bed for the Rolls Royce Kestrel engine ?
Love the music!
At time mark 7.54 how was this done in 1976? Or is he trying to speak too quickly?
Why did you continuously show an obvious jet aircraft with swept wings?
You gotta convince me that a time traveller didnt put the locks back into the flight surfaces XD. Strategic bombing capability was missing during the battle of england.
It finally came to me why it looked a little weird.. the body looks like an upside down spitfire in a way. The plane looked fast just sitting there. You can see a lot of other planes( allies included) in the sleek lines and shapes. Too bad none exist today.
I enjoyed the video as always. I liked the music, too.
They left the gust locks in, so the plane crashed-so history worked out differently.
I agree with other people,dump the music, please
I found music appropriate..content direct and very informative. Great content folks. Why...just curious...after the Hindnburg disaster did the Germans make another aircraft from flammable $ hi+?!
7:43 - A P38???
The Germans were almost onto the right combination to produce a Mosquito type light bomber, using speed as it's defence against fighters.
Throwing out the extra crewman and machinegun, I know it would have topped it's previous speed.
Of course, once they discovered the damn thing liked to burn, it could only ever have been used for civilian purposes far from the front.
Electron is magnesium used extensively in the aviation world
Ive heard of it now
Volume to zero. Reading the transcript instead.
Nice looking airplane.
I built a model of this aircraft, which was also when I first learned about it.
Wever was a strong advocate of strategic bombing and one of the few voices that recognized that the large distances in the inevitable conflict with Russia would require a long distance heavy bomber capable of bombing factories East of the Urals. Goering and others believed the war would be over quickly and a heavy bomber would only consume scare resources ( which was true) His loss really setback the program of being able to inflect damage to the industries that supplied the weaponry that the Germans would face on the battlefield in the East.
So the first use of the elliptical wing tip was by.....
Not the first use but in the Interbellum knowlige and people traveled freely. Germany choose for the easier to mass produce trapezium wing.
Probably Frederick Lanchester in 1906.
it your genius idea of including elektron in their aircraft, isn't it?
Love your videos, but this music is sooo annoying that I can’t watch anymore
As with all German words containing the letters 'ei', the emphasis in pronunciation is on the second letter, the 'i' and not the 'e'. Heinkel is therefore pronounced as 'Hyn-Kul' and not 'Hen-Kul'.
Seems like the fellow in the back standing up to shoot or hanging out to hold a camera destroys the sleek designs. I'd hate to stand up into the slip stream. I wonder why the clever Germans didn't put the camera into the bottom of the plane?
A civilian passenger target for Polish anti aircraft guns before WWII. Served on the runs to and back from Estonia and other eastern Germanic interested.
The music is horribly distracting. Dislike, sorry
The background music made this unwatchable. thumbs down.
Maybe we could get some German martial music? Or how about that Luftwaffe March music from the Battle of Britain? 😊
The He 70, a stunning "bomber"? OK. I was bien in Ganymede.
Hungarian He-170 version was faster and generally better as well as used in WW2 - longer than stated here, for long and then short-range reconn. as well as close support! The He-112 had the same wingplan scaled down. And the Yanks used flammable magnesium in the B-24!
Switch off music...
Not "Hen-kel," it's "Hine-kel."
The Japanese bought one which led to in the inspiration for the Val.
fyi magnesium can burn underwater
I can often spot a 'Dark Skies' clip when surfing through youtube just by the opening title : it's usually something slightly outrageous or annoyingly overstated. Possibly, having been interested in aviation for seventy or so years, I know too much. But ...... I avoid Dark Skies youtubes, they are ridiculous.
Why keep showing a FW-190 being shot down?
Good info, but I had to thumbs-down because your commercials stink
Screw the others,keep the Music!
Screw the others, dump the music!
Czlowieku, spowolnij ten swoj terkot!
Heinkel: Hine- kul not Hen-kel.
This was the plane that was copied by the British, they called their copy Spitfire.
Bloody music, had to stop watching
Feet and lbs.should be included too for your old school viewership.
M.p.h. too
That music ZUCKS
I do like your kids but I stopped watching very early on. I hate your choice of background noise instead of proper music.
Absolutely clueless shambles of unrelated assorted video clips that contradict the shambolic commentary. E.G. commentary about the fitting of a V12 Mercedes DB601 engine. While showing a totally different radial engine being built.🤦
Heinkel is pronounced "heyn-kel," not "Hen-kel" A henkel would be a handle, a German champagne brand, or a German chemical Company.
Bizarre mishmash of footage…..
Complimentary algorithm enhancement comment!😊
Its pronounced 'Hainkel', not 'Hinkel'.
It's NOT "HAIN-k'l"; it's pronounced "HINE-k'l".
“The background music is annoying 🤓”
A very long way from stunning as a bomber. A nice looking plane and fast in its day, but useless in serious combat.
That's where the spitfire got it's wing 🤔
Far too much dreadful schoolboyish flowery language and too light on facts. Unsubscribing, as I've heard enough of this nonsense.
