Once again thank you to Maeson for his amazing music. Check out his soundcloud here: / tracks - Věda a technologie
I guess your videos are ok
Still salty because my thumbnails are so good?
Wendover Productions You 2 need to collaborate and make a video together.
Wendover Productions omg 😲 wendover productions! )
(I'm a subscriber)
OMG LOLOL I guess - the two of you should make more videos together!
You are both AMAZING! Need MOAR.
Wendover Productions Whaaaa?????? omg omg omg omg
Dude....I wouldn't want to fly in any plane described as "ground breaking"....
sqlblindman, pretty good pun you did there
I thought of it first.. but didn't publish.
sqlblindman Damn good point!!!
The Titanic was a "ground breaking" design too...OOPs
Came here to say that. Like for real, couldn't have picked a worse phrase to describe a plane.
"groundbreaking plane"
i hope not
TheFloatingSheep lmao
lol
No. That's doubtful. It could probably run full speed into the ground and the ground wouldn't get hurt much at all.
Peter Kosen don't be *_that_* guy.
WubzPlays -- Who? Me? But what If I *am* "that guy"? :) The thing is made of Tupperware. It's not gonna hurt the ground any. (I've been making fun of the 787 ever since its design phase. The company I work for makes the nacelles for the thing -- for both the GE & Rolls Royce engines.)
My nephew has decided to go to college for engineering because of your videos. Thanks for the high quality content and keep it coming!
That is great. These types of comments mean a lot to me
Congrats to him!
Good for him

Real Engineering Do fighter planes suffer the same window crack problem
Fighter planes are not pressurised, so no. That's why fighter pilots wear flight suits. They will suffer from fatigue in other ways, but not from cabin pressurisation.
Real Engineering ohh thx for the answer
why people don't use iron instead of aluminum to make a aircrafts body
Real Engineering: which software you use to make these videos
Did I miss something? Where is the answer to the why so big?
***** Thanks! I didn't get the "THUS" part for bigger windows. Concentration or me is equal to how well I sleep, didn't sleep well last night.
Because they are able to make them bigger without putting extra strain on the fuselage thanks to carbon fiber.
because bigger windows make the passengers more comfortable. imagine being stuck in a room with no windows sort of concept.. so a bigger window would be better in this case. also because the fuselage is made of composite, and is able to withstand higher stresses, the cabin pressure in the cabin is greater in the 787 as well.
I guess after all that, the answer is "because they can." There's no engineering reason to make them bigger, it's a marketing reason (people like big windows) and the engineering allows larger windows.
Dragon Skunk composite materials having a higher resistance to fatigue crack propagation (through the fiber reinforcement etc) allows the design to be larger and withstand the higher stress field that would cause an aluminum body to fatigue too quickly
So you get a good view outside.
15october91 haha explained within seconds
15october91 t
no
real engineering is slowly starting to turn into wendover productions
LARAUJO I have been working on planes before Wendover hit puberty ;)
LARAUJO Wendover = rekt
I like both productions Real engineering and wendover
And on the dreamliner you said the flight attendant controls the master for the window shades, but there is a trick to override that. Hold both for 10 seconds
better than turning into Micheal from Vsauce
I dream of a plane with super big windows. No, scratch that, a transparent plane! Oh I can imagine the fear. but it's just awesome.
BlackEagle352 there is a plan to develop a plane lined with high resolution screens that display the sky outside or pretty much anything you'd want. it will be like travelling in a tube of cinema.
Glass bottom plane anyone? (Just like the boats but much scarier)
BlackEagle352 *looks down*
When it is finally built and you onboard such a plane. You'll find your self in a plane with transparent but DIMMED ENTIRELY, like a plane without any window at all. Then you'll say FUK IT
BlackEagle352 wait wat if u need to use the toilet? The toilet will be transparent....
Loved this one! Side note - if you ever wanted to branch out into engineering ASMR I think you would make a killing!
Ayyyyy clark!
Should really be "How can the Dreamliner's windoes be so big?"
*Teach mac users to spell Windows
FTFY
I fly the 787 twice every week between Chicago and Dallas. I consider myself incredibly lucky when I realize that many people will get a chance to fly on a widebody airliner perhaps a few times in their life, and probably never fly the latest and greatest. I never take for granted just how incredible flying the Dreamliner is, both from an engineering and passenger perspective.
Great video and channel!Just discovered it.
Warm regards from Rio de Janeiro!
Jayme
I've flown on the 787-8 and 787-9 a total of maybe 60 times and starting in another week I'll be flying on one about once per week again. They're comfy in the back and quiet in the cockpit. When I sit up on the flight deck it's noticeable how much less wind noise there is because of the nose shape. From a pilot's perspective I also like that it has electric engine start rather than pneumatic bleed air, plus it has a 5000 psi hydraulic system compared to the normal 3000 psi systems on other airliners.
What a beautiful takeoff shot, holy shit
Fantastic video, great work!
You hardly talked about the window lol
that's because the reason is "so you can see outside better"
I look forward to that composite materials video. I've heard a lot about them, on this channel and elsewhere, and look forward to understanding what makes them tick.
Excited to see the next one! As a materials engineering major, it's really important to see someone on CZcams with the same passion. Keep it up!
You probably get this a lot, but I wanted to just say that your videos are very inspiring and interesting. You make very complicated subjects extremely easy to understand, and make tiny little details on planes very interesting. Thank you so much for helping me, and many other people, understand engineering better.
Speaking of engineering, a plane, being 'ground braking' may not be such a good thing. :D
0:42 Why does it look like it was flying vertically?
Because it was.
soren Pretty much!!! That was AWSOME!
HighOffLemons because it was, there we no passengers on board and there was not much fuel
It wasn't, that was camera trickery. The actual angle was about 40 degrees -- which is *big*, but far from a straight angle.
Fernie Canto I think the 787 Dreamliner can actually preform a vertical takeoff but I maybe wrong
Fantastic channel. Subscribed! Your 2 second footage of Ireland from the plane gave me nostalgia, I lived there for 6 years and moved 1.5 years ago. Remember those flights in to Dublin fondly. Miss Ireland loads! Keep up the great work!
Very interesting! I love learning more about planes from your videos. Great job!
I flew from Warsaw to Mexico Cancun with LOT polish last Christmas with the 787 it was AMAZING I flew business.
0:42 "Good afternoon, ladies & gentleman, your Capt. for today is Chuck Yeager...and your Co-Pilot is Patty Wagstaff...."
Damn, I'm looking forward to your website ;). Keep up the good work!
Your videos are amazing.
Thank you so much for producing such in depth scientific material.
Wow, I have never heard about electronic dimmers. Do they use liquid crystal to block the light like those cool office glass windows that become opaque in seconds? Never knew this was on aircraft now. Cool! :D
Wow, nice. 7 min video felt like 1, good job man.
This is a great site. Your videos teach the basics of engineering, and have helped me better understand some things I've already learned. Thanks!
wow I'm looking forward to these composite videos, I would love to work with the material in future design projects
I just want to say thank you for not using clickbait titles. You clearly state the topic of the video. I now know more about planes than before.
Thank you
When he says "part" i hear it as "parrot"🤔.WHAT??!!!!😂😂
Dan It’s his accent.
thanks for explaining so simply and clearly!
This video is awesome! I used it in my Finite Elements Analysis thesis.
nice video but u didn't give the answer
Dhaval Shrimali well he did if you connect the dots
+Ethan Arpin No. He stated why circular windows are better than square, and went into detail about the stresses on the fuselage. He never mentioned why bigger windows are superior to smaller ones in any form.
Kenvo connect the dots of passangers satisfaction of having great view, stress concentration reduction by having large oval windows and the advantage of having composite material
The composite materials means that the fatigue failure from being used over and over again in different atmospheric pressures happens less often meaning that the reason for having small windows doesn't matter as much anymore resulting in larger windows for the passengers to enjoy.
yes, there is less fatigue now because the passengers enjoy their flight more
0:46 bruh you wanna stall
Once again my friend, thank you for the phenomenal video!
Keep it up!!!
Just found this channel after a night of sesh, glad to say with all the maths and physics channels I watch I can finally fill that engineering craving I've had for ages. And we're Irish so big plus :D
plz do a video on submarins :)
An air india dreamliner window had cracked once... i think the flight was from delhi to sydney
techlover forever
when she finally opens bob
Well, it's india, glad that happened
Gustavo Hernandez Go fuck your self
it wasn't a 787
and for your information it didn't crank
0:37 god damn that looked sick
I study mechanical engineering and am currently doing a course in material science. And I absolutely LOVE your videos, they have lots of attention to detail and always connect to fascinating real-world applications and history. Easily my favorite engineering channel on youtube.
Car--KEEEERSS
i would hate not being able to close the shade
Software but you can. There are individual dimmers on each window.
》 InsertNameHere 《 Nope he said it was controlled by the stewardesses via a master control!
+squach623. Each window has an individual control but there is also a 'master' control. You can see the dimmer, with it's 5 pre-set levels of shade at 2:08.
You know how flight attendents normally tell you to close the shade during take off and landing? Well the idea is now they don't have to. They can just do it. During flight, passengers can dim it however they want.
wow im glad i found this channel , i cant wait for the next video
This channel has quickly become a new favorite of mine.
"Why Are The Dreamliner's Windows So Big?" Too better blind you when you open the shades.
It doesn't have shades...
I always try to figure out where the sun will be when I book my seat. I like to look outside without being blinded or cooked by the sun.
I do this, too :)
since making holes in the fuselage also weakens it why have windows at all? Screens and cameras would given everyone a window seat without making big holes in plane.
Because people like windows, and for now, we can afford to put them in. Once passenger planes are going hypersonic, then we won't have windows. Until then people want to see out of real glass. I mean I wouldn't mind cameras, but I am not the majority of people.
Uno G Weight gomer! Plus the fact that Nobody is gonna get in a sewer pipe with wings ! You couldn't give tickets away!!! More people are claustrophobic than are scared of spiders man! Most people don't realize it because they have always , subconsciously avoided tight spaces! Put 400or more people in a tube without windows and then hurl it down a runway with 2 to 4 screaming vibrating jets and I bet 85% of them would freak the hell out!!!
people would get sick as hell
And one reason is that without windows airliners would not buy it. During takeoff and landing many airliners require window blinds be open so that in case of accident evacuation would be faster and rescue crew is able to see through windows and make decision to go in or not based on that.
To reduce weight.
Dude this is absolutely legendary! Awesome content!
Wow these videos are getting really really good. This and the f1 video from last week are the best two imho
Wow Ireland
Wowwwwwwwwww
Redkeymon Savage wat about it
Funny how you pointed out the mistake of engineers who design the Comet and at the end of the video, your patron is" squarespace"😂
The videos are getting better and better!
As a kid I remember the British made Vickers Viscount , a small 1950's era 4 engine turboprop liner with its uniquely large windows (bigger than the 787) It was the only airliner where I could easily see the passengers inside.
*Makes a video about WHY the 787 windows are so big*
*Never explains WHY*..... Instead, explains the difference between square and round windows
Unfortunate choice of words... "to fly in this GROUNDBREAKING plane". I would prefer to not be in it when it breaks ground somewhere. :)
Great video & honest concepts. Special thanks for the comment about the enjoyment of flying as a passenger, I always insist people of the useless pain of the fear of flying and tell everyone about the multiple joys they can experience in each flight. Thank you for putting those pleasures in plain English.
I flew in the 787 to and from the US in early January. On the way there I had a window seat, had a phenomenal view of New York.
Window seats arent my priority. Front row seats are. Give me all that leg room
Or the exit row on a 737 or A320!
Front row seats can be tricky to book. Usually the pilot and FO want to sit there.
notification squad?
Caleb Horlacher you liked your own comment
y'all my boys
Brosef FTW how can you see that
aiiii my names caleb. xD
Doples nope
Nice vid!, looking forward to watch that composite materials video
Great communication between designers and engineers to come up with a nice feature to improve the flying experience.
Why Do You Write Your Titles Like This?
Marcin Bator everyone does it now, because it looks more 'professional'
because it's a Title. In typography, that's actually referred to as 'Title Case', as opposed to 'Sentence case'...
blauphus2 shit... You're right... I've been watching tens of videos titled like this every day and I didn't notice... Maybe I noticed this one because the title is so long. Thanks! Just learned something today ;)
awesome!
Marcin Bator looks more professional
Unfortunately this video is not up to your usual quality standards, but rather mostly a reiteration of Boeing PR. Yes, the 787 was revolutionary by Boeing standards, but not when compared to the Airliner industry as a whole, it is Boeing playing catch-up both in terms of technology as well as market positioning. It is mainly a reaction to the A330 killing the 767 in its market and despite being 20 years younger, the Dreamliner has gained no significant advantage to its European counterpart.
Isn't that just the story of the aeronautical manufacturing industry over the past forty years? Airbus and Boeing have immensely lengthy battles to decide which of their very similar planes is best, and while Airbus always wins, no company can give the other a killing blow. Yes, the A330 and A340 were excellent planes, but that didn't stop people buying 767s and 777s, in the same way that the A320 still being arguably the best commercial airliner ever built doesn't stop people buying 737s...
Robert Faber Which aircraft is best always depends on the needs of the airline. The most technologically advanced plane is not neccessarily the most economical one when considering purchase price, time to delivery, reliability, crew training, spare parts and of course the balance of capacity, weight, fuel burn and range.
That being said, both the A330 and 787 are optimized for very similar missions and offer very similar economics with the A330 being a much older design. Under these circumstances, calling the 787 "revolutionary" is pure hubris. It is a good plane, on par with the competition. Nothing more, nothing less.
Valentin Brückel Yes, but the A330 and 787 don't really directly compete, hence Airbus not discontinuing the A330 in favour of the A350, but keeping the A330 (in A330neo fashion) alongside it.
The A350 is closer to a 777 in size, hence the A330 remaining in production. It is 787 vs. A330 and A350 vs. 777
JZ1917 It is if you're just looking at passenger numbers, yes, the A350 there being more capacious than the A330neo because it also takes over from the longer-bodied A340 variants. However, in terms of fuel efficiency, range etc. it very much is 787 vs. A350.
Really love your videos! I really hope you're able to grow your channel so more people can some and enjoy your fabulous content! Looking forward to your next video! Sounds really interesting : )
seriously one of my favorite videos
I still don't know why the windows are so big?
Because the material is stronger, so they can afford to make the windows bigger.
Title shoiuld be "How" they made the windows big, not "Why".
jpdemer5 the why is because people like bigger windows. They enhance the experience. This was said very early on, so i can see how someone might lose focus within the first minute /s
People like shut bigger windows? Shock!
you never answered the question lol
kindly upload more about aircraft and aviation your way of telling is incredible
excellent and entertaining video. Thank you for producing this video!
sold out to: Boeing, otherwise good but so awkwardly one sided :/
True. The A350 and 787 could trade blows all day, and the only reason the former would win that argument is because of Airbus' record as a company, not because of the plane, because the two really are very similar. The A350 is more advanced in some ways, the 787 in others, but neither really takes the crown, and yet both are tremendous steps forward in ordinary, everyday aviation.
Airbus and Boeing have some fairly different design approaches, particularly regarding composite materials. They're not as similar as you may think.
Would be great to see a comparison video on this channel about the A350.
Robert Faber airbus' record as a company? If we are talking about company record, airbus loses by a nautical mile. You're comparing it to one of the oldest and most prominent airplane manufacturers in the world. Boeing dates back to 1917. Their airplanes were well used in WWII, and is why many bombers start with a B as in B-17 even when not made by Boeing. Boeing was instrumental for their experience during the Apollo missions. Right now they are helping design a large earth based telescope that will produce better images than hubble by using their eperience with aerodynamics to reduce vibrations caused by wind hitting the walls of the facility. When finished, it will be the largest telescope ever built.
Now what has Airbus done?
Nathan Lang fan boy warning
1st
No one gives a shit
Fuck you dude
If you wanna attention, talk to your family.
Do something useful with your life instead of sitting on CZcams waiting to be the first to comment on a video. Commenting "1st" is just the same as yelling "Hey everyone, I have no life!"
Joel Jackson Do something useful with your life instead of sitting on CZcams waiting to reply on a video. Replying to "1st" is just the same as yelling "Hey everyone, I have no life, so I complain about people commenting 1st"
The globe at 1:21 makes it look like we're literally in an ice age!
I’m hoping to get an apprenticeship in airbus in the UK, after getting through the test, your videos excite me about aerospace engineering so much
A350 is better tho
Jamie Clumpas Not for the use that the Dreamliner was made for.
better at what? can't really compare the planes in their intended market, can compare some of the technolgy that makes the plane but i dont think one can really compare either aircraft, its the same as comparing the A320 and the 747, just isnt a compatible comparison.
And i would HIGHLY prefer to fly on the 787 to the A350 :P dam i loved servicing the 787's compared to the 350, quiet APU and very logical and well engineered access doors and servicing systems, the A350 was a bit to complicated. This said the 350 we had was not a commercial operator but a trial prototype so maybe the production model will be different
Jamie Clumpas 777x bro
Minime gaming
now thats a sexy plane too, folding wing tips, awesome idea taken from Naval Air Arm's :P
folding wing tips? The 777x has wing rakes which is more efficient lol
Looking forward to your visitations of the companies!
Another cracking video enters your portfolio! ty.
Love your vids! Especially about aviation
0:17 what a great screensaver
Looks great
So awesome video! You are one of my favorite youtubers! hope it goes good for you!
Ived also gone into the dream liner and its so nice!
Note to the channel owner.
1) Nice vid.
2) on concrete ships. One from WW 1 recently broke up in Monterey Bay California. It had been docked for many decades and took abuse that would have LONG ago resulted in a steel hulled ship being destroyed.
There is a new reinforcing material being used in land based concrete. It is basalt fiber. It is extruded molten basalt fibers bound by resin. This new rebar is being used in place of steel. It is 5X as strong and weighs 20% of what steel does. However its biggest advantage is that it doesn't rust, and it has thermal expansion properties similar to concrete. This means being able to make much thinner concrete structures and not worrying about water induced problems with the rebar.
This would make concrete boats and ships much more attractive. Think about it.
Watching all of your videos! still, have few then I ring the bell :D
keep up the good work!
One of my favorite parts of the 787 windows was the dimmable film. Was very excited to learn you can buy the film for home use.
Great job with this video brother!
love your channel keep it up bud
Thank! I rode in one recently and I was wondering this!
Hello from Donegal! keep up the videos!
This channel is the engineering version of Kurzgesagt ("In a Nutshell"), and highly educational and fun.
I wish they taught middle and highschool like this (and had Engineering classes), there would be so many more engineers and scientists in this world!
366k subs in a year. that is pretty awesome. that was the reason I subbed. I haven't seen your videos much.
ground breaking planes and final destinations?
great video!
Looking forward to that carbn manucturing video !
Keep up the great work!
Awesome video, as always.
Pretty cool man. Thanks
I was on a Dreamliner from LA to London last December. What I noticed is that the headphone jack for the tv is terribly placed. My headphones kept getting in my food when I was eating the in flight meal. And the isle seat arm rest wouldn't move up so it was really hard to get in and out of the seat when there was food or stuff on the table. But that rainbow lighting is trippy though
Lad I love coming home and seeing my country IRELAND it just clams you so much
Great video keep up the good work
