Destroying Flat Earth Without Using Science - Part 3: Airplanes 

how can the earth be flat if my life is continually going downhill

"We have a lot of members AROUND the GLOBE." - Flat Earth Founder

My flat Earth friend first said there are really no flights between Africa and Australia but he changed that to "they have them but the passengers are all put to sleep and are awakened upon arrival, never knowing how long it really took." That's even more ludicrous than the first excuse.

As a Brazilian I can confidently confirm that all of the southern hemisphere is indeed located on mars

As a South African, I'm just a tad bit surprised to learn that where I live doesnt exist

Flat Earthers be like: “No! You’re wrong!” Me: “Why?” Flat Earthers: “Idk you just are!”

POV: you're looking at the newest comments to find more flat earthers to laugh at

6:01 - Hey, did you just claim that the Easter Bunny isn't real? That's fighting talk. Next you'll be claiming there's no Tooth Fairy 😮

Winning an argument against a genius is hard, but winning an argument against an ignorant is impossible. Bees don't waste their time at explaining to flies that honey is better than sh*t.

A flat earther just told me gravity doesn’t exist

The earth MUST BE flat, cause my tiny brain can't get it's a globe.

Flat-earthers living in the northern hemisphere: "the southern hemisphere doesn't exist!". Flat-earthers living in the southern hemisphere: ...

As an Australian I can confirm the southern hemisphere actually doesn't exist

Since I know this information already and I’m not a flathead, it gave me the opportunity to notice your very cool Led Zeppelin picture on your wall. Nice!!

Please, Dave, go to a flat Earth conference and ask them questions they can’t answer! I bet we would all love to see that 😁

As someone who lives in the southern hemisphere, it is quite a shock to learn that I don't exist 😱

The great circle argument also holds for flights in the Northern Hemisphere. On my very first transatlantic flight from New York to London, the pilot announced that we were flying over Scotland at the time and were about to start our descent to London. Everyone knows that Scotland is way north of London. I wondered why we didn’t just fly due east from N. America to London. A few years later, I began a career as an airline steward for Pan Am. They explained about the great circle routes in our training. Because of the curvature of the Earth, the distance is shorter to fly in an arc to a lower latitude, lessening the distance.

When I flew to Germany from Calgary Alberta we took a "short cut" over Green land. That route coupled with the surprising short flight time totally debunks flat Earth.

I joined the flat earth forum and I saw someone bringing this argument: one actually replied "they drug you to distort your perception of time"

"No amount of evidence, will ever persuade an idiot." - Mark Twain.

the reason they don't travel over antarctica is because they have to be close enough to make an emergency landing in case things go wrong

Also, the idea that an airplane should *dip its nose* to go down is the most idiotic ever. Have they even seen an airplane landing in their entire life? :D

man this guy is harsh and I appreciate it lol

Sorting the comments by new was a mistake

I’ve flown from the U.S. to Australia, and from Australia to South Africa. Both flights were close to the same length - within an hour or two. I made this comment on a flerfer forum once, and I was told all sorts of crazy things: 1) I’m a liar. There are no flights from one part of the Southern Hemisphere to another. 2) The plane - a 747 in both cases - flew much faster from Australia to South Africa. MUCH faster. 3) Everyone on the plane from Australia to S.A. was put to sleep with some sort of sleeping gas, so the flight only seemed shorter because everyone slept through half of it…plus we slept through a refueling stop somewhere in between in a 747 wouldn’t have the range to fly that distance on the FE map. 4) Australia and South Africa were actually places in the Northern Hemisphere and we were all fooled into thinking we’d flown to the Southern Hemisphere. These were all ridiculous, of course. 1) I have actually made those flights, although they were several decades ago. 2) If 747s could fly twice as fast as they do from L.A. to Sydney, why wouldn’t they go twice as fast on ALL over-water routes? Cutting a 14-hour trip to seven hours would be wonderful! 3) Funny, but my watch - and all the clocks in both countries - said I was on the plane for about 15 hours. Do they reset the clocks for everyone at your destination just to fool the passengers from one flight? Plus, if we could be safely gassed and put to sleep with zero ill effects on planes, why not do it for all long flights? I’d happily consent to it if it meant I wouldn’t have to sit in that uncomfortable seat for 14 hours, unable to sleep since I can’t ever fall asleep on planes. I’d consent to it on short flights, too! 4) As an astronomy buff, I spent quite a lot of time studying the night sky in the Southern Hemisphere. Orion was upside-down and there were many constellations not visible at all from the Northern Hemisphere. Everything rotates around the southern star, too. These claims that flerfers make are easily verified or debunked. Just get on a plane> I guess flerfers are all too poor to afford plane tickets.

Flat Earther: People in South Hemisphere doesn’t exist Philosopher in South Hemisphere: Yes you are right

Winning an argument against a smart person is difficult. Winning an argument against a dumb person is impossible.

Dear Dave. I just finished watching the video where you trash a flat earth bald guy. Then realized, by googling your name, that you are the same dave that refreshes my physics back from college, gives me useful tips to address my own teaching and reminds me why I was trapped by the wonder of science. I usually turn to your channel when the traffic on Mexico City wants to drawn me, and you give a good amount of oxygen to the situation. On behalf of my students, my kids and miself, thank you for your kind and serious dedication to explain things. You make the world a better place.

How come no plane has ever flown to the ice wall and taken pictures????? Maybe because it doesn't exist??? Ya think??

The fact that this video needs to be made honestly hurts my soul.

Toddler: 😭 The Easter bunny isn't real Flat Earthers: 😭 The Southern hemisphere is real

looking at the azimuthal equidistant projection, you would expect a flight from perth to sydney (west to east coast) to take three times as long as a flight from new york to LA. but since we live on a sphere, it's not. it's an HOUR SHORTER

I love that you are still replying to comments on this video dave

it's absolutely insane to me that you need to make this video in the first place

The fact that this topic is even up for debate is a depressing sign for humanity. Eventually, these people will have kids that learn from them. Sad really

I am a retired airline pilot with a 38-year career flying airplanes worldwide. The calculations we used to complete transcontinental or trans-oceanic flights were absolutely based on a global world using mostly Lambert Conformal Conic projection to convert the sphere into navigation charts. We used Great Circle Routes to shorten flight distances and times. Great circle routes do not exist on a flat earth. I have yet to see a flat earth map that would provide accurate distances, times, and headings for any long-distance flight. In fact, were I to plot such a course and use the headings provided by a flat earth map, God knows where I’d end up, and likely the distance and therefore the time would be wildly in error. Imagine an air transport industry using such folly.

Isn’t it crazy how the world actually works. The fact people exist who believe the world is flat is mind blowing

Pro tip: sort comments to ‘newest first’ to see all flat earth comments.

"By looking at objects and thinking with their brains" Slow down there man. You're asking too much from these people

Thanks. I'm from Chile and I traveled from Santiago to Sidney on 2015 (my final place was Japan).... and yes, it was a straight and smooth flight for 12 hrs.

bold of you to assume flat earthers have brains to begin with

The real problem here is that I don't know which comments are real and which are trolls.

Flat earther : Southern Hemisphere is didnt exist!!! Flath earther in SouthernHemisphere : 😐

Just ask why theres a Cresent on the moon. Looks like something spherical is between the sun.... oooh!

I was looking for a flight path and I found this video that put them in my face. Thank you for making it.

This was well done. We all knew this information, but you demonstrated it so well. Thanks.

An antarctic scientist on a flat earth: 👁️_____________________________👁️

This argument won't work with a flat earther because it uses logic and reason.

Reminds me of that guy who insisted Australia wasn't real

I have been reading the new comments on here and I'm surprised to see that you still respond on a video that is 2 years old. I haven't looked properly on your channel but have you spoke to a flat earther who changed their perspective and thinks the world is a globe now? If so, was there a specific point that made them think twice about their perspective? But I'm loving the videos!

I find it funny how teleportation, reality distortion and a multi-trillion dollar conspiracy are in the mind of a flat earther, less absurd than the idea of the Earth being the same shape as the rest of the shit we see in the night sky.

their argument is. "all pilots are ex military just remember that". Like every member of the military is some kind of paid secret keeper....

I was disappointed that we had to teach this to fully grown adults, but after thinking about it a little more, it’s even more disappointing

Sometimes I see Flat Earthers complain that "You need to get permission of the government/UN/God in order to fly to Arctic/Antarctica/The Edge" And I'm like... "Umm... isn't it standard procedure for any flight, anywhere? That you ask for permission to fly anywhere?" Why do they expect somehow Antarctica to be any different? Because no one owns it? They still need permission of your ATC to use their airspace in order to get there. Because we all know those Flat Earthers are not going to be launching planes out in international waters.

Just the fact that flat earthers exist blows my mind.

"Thinking with their brains" See, that's where this whole thing goes off the rails............

I don’t think flat earth ears know how seasons work

QF28 flew over Antarctica twice in as many days last month

If you’re a flat earther go find the edge, you’ll be renowned you’ll be a hero, you’ll become a millionaire. Now people are saying an army guards the edge, go take pictures of the army guarding the edge you’ll be a super hero,

I find it amusing to hear flat earthers make references to the northern and southern hemispheres. You know, the hemi*spheres*. LOL.

As an Aussie, I can confirm that I do not exist. Therefore neither does this confirmation.

In civil engineering we have to allow for earths curvature in long spaced bridge piers for instance or very long "level" ground slabs. Even over not too great a distance with a laser level you can see the difference between mean spot level and the straight line. Using these surveying instruments, basic triganometry and pi, you can work out the diameter of the Earth, we do it all the time with young apprentices and graduates. 😊

POV: you are looking for flat earthers counter arguements

As someone from the Southern hemisphere i can confirm, we don't exist

Even if the earth was magically cut in half and the southern hemisphere disappeared, the most south part of the north hemisphere will become the new south. How distorted would things be then? BTW love your videos keep up the amazing work 👍

If the earth is flat how can you fly from New York to Japan going east and fly from california to Japan going west? Wouldn’t you fly off the earth???

I use to be a flat earther. I started doubting it after many said it was round. So I studied more and more, it wasn't until I graduated Kindergarten did I mean the earth is round.

5:10 I've went around the world, and lived in Australia for 3 years. I can positively say that during the flight, I did not disappear from existence.

Come across a woman in an FE Facebook group who said she knew a pilot, that multiple members of her family worked for NASA and had been pilots in the air force and all were FE belivers. I was literally gagging at the smell of the bullshit! 🤦‍♂️😂

The best one I like is that they use distances that are less than 1% of the "suggested circumstance."

Best line ever: "How does the wind know which way the plane is going?" 👍😁🏆

I find it hilarious that if something doesn't align with their theory, they just deny it's existence

I just looked at a globe from the 16th century yesterday. They didn’t know about Australia yet, but they sure did know that the earth wasn’t flat.

I am a pilot. There are, in my profession, more evidences. 1 - Magnetic field, that provides orientation. We use a compass pointing toward the magnetic north and we must to compensate this effect when using a map. Because the north is continuously moving! Someday, far in the future, it will be placed at the south hemisfere! 2 - G Force (gravity). As an acrobatic pilot, we have to consider G force, during the maneuvers. There is an instrument inside the aircraft to measured it. 3 - Inercial navigation. Precise giroscope is used to give us the position of the airplane, anywhere in the globe. This device works because of the movement of the Earth. 4 - GPS. How the satellite system is, in the flat earth model? 5 - The explanation, or calculation of Lift, the force needed to beat the Wheight (gravity) that allows machines heavier than the air to fly!! Enough? I have more...

Why does this even have to be explained to other human beings?

probably my favorite line tweeted by the OFFICIAL flat earth society on twitter, "We have members all around the globe", and you can guess what the internet had to say ab that

I love how ruthless and blunt you are with flat earthers. They deserve it. It's not just ignorance. It's willful ignorance. Because they are either too stubborn or too afraid to let go of their belief no matter what evidence they are presented with. You could take them on a spaceship and show them the earth is a globe and they'd still deny it and say the windows are just tv screens or something, and it was all just an elaborate hoax to trick them.

This is the best flat earth debunking video I have seen.

For those keeping score, the specific flight path in this video finally resumed services after roughly 2 and a half years. QFA27 departed Sydney airport at 12:51 AEDT on Sunday October 30th and landed in Santiago 12 hours, 2 minutes later.

When flat earthers realize they’ve been breathing from the atmosphere & not the atmosflat. 🤔

If the earth is flat, what is a nautical mile? 🤔🤔

Distortion Over Latitudes: 90°N - 0 70°N - 0.0206 50°N - 0.0861 30°N - 0.2092 10°N - 0.4178 10°S - 0.7723 30°S - 1.418 (Places are distorted more than 2x) 50°S - 2.801 70°S - 7.165 90°S - Infinity

As a cyclist, I can assure you the wind always knows which way I’m going. It’s always a headwind heading out, and a headwind when I turn around to come home.

As a South African I am very proud to be living on the hemisphere that blatantly destroys the flat earth concept. I'm not even going to call it a theory.

The fact that you need to make and watch this video is mind-blowing.

RIP Bob. "A 15 degree per hour drift" Thanks Bob.

No joke a flat earther told me that propeller planes legit can't fly, even after I've told them that I've flown in one

Fun activity 1. Get popcorn 2. Get comfortable 3. Sort by new 4. Enjoy the show.

What do flat earthers think would happen if you reached the end of the flat Earth? Or do they just hide behind the idea that we’ll never reach it because of the water?

Had a passenger challenge me on this after I flew them across a continent. They showed me a video of another pilot from my company accidentally saying that the world was flat. I said he just miss spoke man. The showed them the inertial reference system and said this thing is so accurate it measure the rotation of the earth when it calibrates itself and it doesn’t need gps to figure out where it is on the planet and it’s been in service in one form or another since before you were born.

If the earth was flat, cats would have pushed everything off the edge by now

Being an astrophysicist I can almost feel physical pain when flat eathers put their stand. I mean did I just waste my countless nights staring at holographic stars and planets😫.

My flat earther friend is even worse here because we literally live in south, not just that, but we’re at the Tip of Africa, Cape Town.

i fly airplanes. we know the earth is a SPHERE. this debunking of flat-earth is just too hilarious! hahahaha... good one, Prof. Dave.

As a Brazilian, I can say that the southern hemisphere exists

As a person living and breathing in Australia I can personally confirm it’s existence 👍🏼

Have you ever heard a flat earth er say something like “Amelia Earhart tried to fly around the world and got lost so she must have flown off?”

Flat Earther: There are no direct flights in the Southern Hemisphere Me: No shit sherlock, since on a Flat Earth, the Southern Hemisphere doesn't exist, because in order for something to be a sphere, it needs to be round.

In the Netflix documentary called “Behind the Curve” the flatearthers proved themselves wrong with their own experiments
