Forgot to mention that to hold the aircraft together, the fasteners actually need to be installed
Maybe the narrator works for Boeing!
Instructions unclear, door does not seem to work as a flotation device.
No shit Sherlock, what was your first clue??
Maybe someone should show Boeing this video. The last part has some references they can take
LOL you took the thought right out of my head
I just want to know where the missing plane is
Another boeing plane has engine cowling falling off just now..
I'm a former Turbofan Test Engineer for Lockheed and Rolls-Royce at Stennis Space Center from 2007-2012 and tested the Trent 1000 for the 787 during development. A Boeing crew from Seattle showed up for our thrust reverser and VFSG testing. An absolute bunch of ass clowns. Day one they're demanding we fetch them tools and ordering my team members around. I said "this is my facility, your union doesn't mean shit to me, and you can fucking ask me for permission or you can fuck off", in my Marine Corps voice. They listened.
I lost all respect for Boeing during that time. Especially since I heard about the cracks forming in the composite where the wing meats the fuselage. Anyone would have known that was going to happen, but they went ahead anyway. Morons.
I see that workers aren't wearing gloves during assembling.
I wonder how many internal finger prints are left on those glasses.
In the real world, optics are protected by workers wearing finger cots or lint free gloves.
Was probably just for video
The fingerprints don't matter as long as they're not on the reflecting or refracting surfaces.

When I served in the USN I got myself a pair of those Steiner binos, they were expensive but worth every penny!
Did you get a pack of crayons too?
@@Chad-Giga. He said Navy, not Marines. :p
@@Wolfshead009 your right
What hobby do you have that makes use of them, out of curiosity?
No matter how good the bolt are, if you forget to fastening them.....
?🤯
How it's made is awesome!!
I've been watching the various episodes for years!! I've learned a lot!! 😊
I LOVE my fisher space pens! Now I know why! Thank You!
Came for the interesting "How it's Made" content, stayed for the jabs at Boeing in the comment section 😆
Also, pencils are highly unsuitable for use in space craft, Russia uses space pens as well and NASA didn't develop the pen and didn't spend bazillions of dollars on it, just in case you were about to comment that.
That dude's face 😂
the guys face on the telescope one lmao😂
In case you're wondering, those binoculars cost around €1200
nice science great job🎉
Thanks 🌟
Boeing should get in touch with this company.
Lol!
And the media needs to get much more specific on who's fault what is. 737 Max - Boeing. Tires and panel coming off decades old planes - maintenance problem.
I used to wear glasses to see before I had cataract surgery...my glasses had clear prism's so I wouldn't see double, thus I recall I tried to look through some binoculars once and couldn't see straight, so I took off the glasses and was able to see😮...after seeing how binoculars are made, I now know why I was able to see through them then.
Beautiful binocular ❤
Boeing must have missed this epie
How it is made is incomplete without the intro music
Cures the adhesive, not drys the glue.
That upsets me also. Dip sticks anyhow.
@Moffit366 Well, their audience is the general public.
"hammers in the screw"
Wow ❤
Esto es increíble
I've never witnessed this work done in a non-Clean room without vacuum processing and techs who are not wearing cleanroom garb and booties. 😮 Hmmm, I guess we were doing it all wrong then where I worked. 🤔
Anyone else immediately think of Seinfeld when they showed that pen?
No, I just thought the Russians used a pencil
“What did you take his pen for??” 😂
A reologia e viscosidade do vidro é muito alta.
the tech should of been wearing gloves when handling the mirror and anything that goes near it
It was probably a dud, and it didn't matter. But yeah, that was my first thought as well. 🙂
And a disposable head covering.
Very impressive.
Very impressive lies.
@@TheRealHumanPodcastYou seem to be full of them.
There's a few flaws in this video. 1. Why make a special space pen when you can just bring a pencil to space like the soviets did? A pencil is much more efficient, and the shavings can be recycled as wood or use a mechanical pencil.
2. Why make specially machined parts for riveting aircraft when it's much easier and safer to weld the parts. A properly done weld will actually make the area stronger, not weaker like everyone falsely believes. A weld is adding metal to metal, not like adding glue.
Human error is the only issue with welding but of you hire a good welder it's safer because the part won't break or need replacement for several years, if not ever at all, hence why the military requires their aircraft to be fully welded without riveting or fasteners of any kind. It's cheaper to weld than to specially manufacture special materials that can break easier than any weld can (a welded part would have done better on those stress tests in the video than the bolts).
For reference, the reason why the titanic sunk was because it was made by riveting parts instead of welding it. Hence, when it hit the ice, it broke the bolts, and the steel plates fell apart. If it were welded, this wouldn't have happened, and it would have just barely scratched the metal plates, and it would have survived the journey.
A modern example is that the Boeing planes are failing BECAUSE they didn't want to pay welders enough so they all quit so they had to use riveting and fasteners so the plane parts fail BECAUSE THEY ARE NOT WELDED. That's why the military requires welded parts, and most state laws do now as well.
On the pen, it's because the graphite in pencils is electrically conductive so using one in space where it can get everywhere due to low/no gravity leads to catastrophic electrical failures. That's why the soviets started using the space pen too immediately after we created it.
I have a Meade ETX-80 telescope, which I’ve used to view Jupiter and his 4 Galilean moon, Saturn as well as the moon. I also let my next door neighbors look through my telescope and they said that my quality made telescope easily put their bargain-priced telescope to shame. I also have a space pen that I bought from the gift shop at the Udvar-Hazy Center.
@@TheRealHumanPodcast It was about $15-$25, plus it was made in the USA. As far as I’m concerned, it was money well spent.

Google is an amazing tool.
Cool... How old are u?
@@tilligetbig 35.
You forgot to mention the pope imprisoned Galileo even after his proof.
Yo no tenía ni idea como se realizaba esto
Steiner in 44: Unlike our sons and brothers our binoculars can thrive in an Eastern winter with no problem!
😮😮
The binoculars are quite expensive. Over 1300 euros.
Ahhhh 🙂Everyone's favorite narrator
... been around for years and years and years!! 😊
Someone missed high school Physics...
Please elaborate. I love when people find errors
I mean if you couldn't figure it out without school especially in the modern age you've got bigger problems than not going to school, maybe see a doctor about ur negative IQ if that's you 😂😂
who uses that many spacepens?
Terbaik BoBoiBoy 💪💪💪
If binocular without glue should still be strong? the white glue colour did not spoil or like have leaks inside that can't be removed? The eyerest circle should be normal? Like that too odd can accidentally poke own eye if hard material?
Have a reach to not look at telescopes video, it's part of this video anyway: what I see is polishing a circle with hole in the center, some small rockshape stuff - it got coated from mixture on 1 side? Why issit like that anyway needing a mirror? It's not a lens with degree to see long distance? Maybe to cut(he used wrongly? Not the center one to cut into slimmer pieces?) and be placed at viewpoint of telescope?
12mins 8s, nitrogen used such way, can't let it be normal? Isn't it a waste of nitrogen(assuming as dryice)?
@@anasqai Dry ice? Oh I see, nitrogen. No, there is no cooling with 'liquid' nitrogen needed here. They do use nitrogen, same stuff as liquid nitrogen, but at room temperature and in gas form. Not for cooling, but to protect the inside of the pen.
A normal pen uses gravity to push the ink in the pen towards the tip of the pen.
The space pen is able to write in 0 gravity and in negative gravity (upside down). Instead of gravity, the ink is pushed by a gas under pressure. It's the gas that pushes the ink not gravity.
In principle, you could put the pen under pressure with any gasses. But some gasses react with other chemicals, air is an oxidiser and will rust metals. And a few gasses are inert, do not react and are stable (does not change over time to something else). One of those inert gasses is nitrogen and it's cheap. So they used that to put the pen under pressure and protect the inside of the pen. If they used air the ink, metal, oil, ... would oxidise.
In the food industry they use argon gas, also an inert gas, to protect food. Food packed with argon gas stay longer fresh, no air for food to oxidise with.
Faz telescópio que você ganha dinheiro.
Também.
Why would a space pen need to write under water ?
doesn't have to...it's just another function of the pressure...
Unintended feature they capitalized on in order to sell more pens to earthlings? With the manufacturing process if only astronauts used them they would cost NASA (we the people) thousands of dollars each. I haven't had one in a long time but in my line of work with water, grease, oil, and sometimes writing laying on by back is was nice to have.
It doesn't NEED to write underwater. It's just a positive side effect of the pressurized cartridge.
All pens can write under water and upside down
I could get you a good deal on your aircraft bolts. We'll walk down to home Depot.😂
"an aircraft must be able to withstand extreme conditions and stress, so it's critical that the fasteners holding the parts of the aircraft together are made to precise technical specifications."
as anyone told boing that? i think they could learn from this.
why are so many space pens being made how many people we got in zero gravity.
That pen that writes anywhere - why not just use a pencil?
Oh, hey, it's the Markiplier episode.
thank you . ( 2024 / Apr / 21 )
Glue and plastic is meant to fail in 5-20yrs nothing is lasting anymore
Yes, that's why I still have my mom's and dad's metal binoculars from the 50s and 60s!! 😊
They binoculars back then were all mechanically assembled, with no glue. But God forbid when the grease dried up and the lenses would move. Yuck.
ok
Those r not Bushnell ones...those r the best out there
The narrator sounds hot
A pencil can do the same work as the space pen
It actually can't. Pencils present a wide range of issues that make them unsuitable for space flight. The most readily apparent being the issue of sharpening, when a pencil is sharpened, it produces a lot of fine graphite dust and wood shavings which are difficult to contain. Sure, a sharpener with a shaving catcher could be used, but have you ever used one of those that didn't let out at least a little bit of dust? That isn't a big deal in a classroom or art studio here on Earth, but in a space craft, having dust of any kind can be problematic, doubly so when it is highly conductive graphite dust. That dust production isn't limited to sharpening either, even just the act of writing and handling things that were written on can release a small amount graphite into the air, which while it is unlikely to cause huge issues, is not worth the risk when it comes to space missions. All of that said, NASA actually did use pencils on space flights prior to the development of the pen by an outside company at which point they tested and then deployed it because it was superior to pencils.
The myth that developing the space pen cost bazillions of dollars is highly misleading. The project that the pen's introduction and testing was a part of was indeed quite expensive, but the pen wasn't the sole goal of that project, it was kind of just a tacked on addition that supplemented the rest of the work. Saying that the pen cost ridiculous mountains of money would be like saying a car windshield sun shade cost $30,000 because you wouldn't need to buy one if you didn't have a car. On top of that, it is stupendously difficult to get an accurate representation of how much space programs cost since they are so vast, interconnected and involved. Do you factor in the cost of building a safety railing on a walkway in the Vehicle Assembly Building into the "price" of a particular Space Shuttle because that railing was installed while that vehicle was being assembled, or is it associated with general maintenance and so applied to the Shuttle program as a whole and thus inconsequential to the cost of a single rocket? Is it fair to say that the cost of developing the EMU space suit was solely associated with the Shuttle Program, even though suits based on those designs are still in use on the ISS today? Politics, contracts, cross-compatibility of technologies, and many, many other factors all play into the stated cost of any particular space project, but at the end of the day, the number that is stated is really just an educated guess at the proximate cost that contributed to the project in question.
Americans spent millions of dollars developing a pen that would write in zero-g…the Russians just used a pencil.

Last but not least, Russian cosmonauts also use the space pen.
@@resurgam_b7 its just a saying. Ive heard it all my life lol used in place where someone over thinks something.
Only idiots say "a pair of binoculars". That's like saying there are FOUR oculars (lenses close to the eyes). You don't say a pair of biplanes for a unit of aircraft with two wings or even a pair of bicycles for a unit of pedal powered mode of transportation with two wheels.
Only insufferable pedants think that language is based purely on logic rather than convention, usage, and lexical evolution.
A pair of glasses… a pair of pants… don’t take it too literally… hahah
