Why flights don't make sense on a Flat Earth

I will never forget my first day in the sixth grade. A kid said he went to Korea over the summer and that the plane went close to Alaska coming back to Seattle. The teacher said that was strange because, while pointing at the Mercator projection map, it shouldn't have gone close to it. I raised my hand and said I could explain and traced out a short path on the globe from Seoul to Seattle which went over the Aleutian Islands right south of Alaska. I felt so smart on my first day of sixth grade! Then the teacher ignored what I had just done, went back to her Mercator projection map and said, "They went there probably because of the winds from the jet stream."

Pilot here, most modern aircraft do not vary their speed, we fly at the most economical flight level and speed and as your article explained the most we can make up is about 5/10 minutes at a cost of about a tonne of fuel, now here’s the thing, we don’t carry a spare tonne of fuel just for laughs, if we need extra fuel at the planning stage we can carry it but the problem with delays is that you don’t necessarily know that we have one until we get going by which time it’s a little late to add fuel. In short, we tell folk that we will try to make up time but in reality it doesn’t really happen. Cheers.

As I think about it, their "planes can fly at different speeds" and "computers calculate the flying time" claims don't make any sense, especially when made together.

I'm working on my pilot's license right now, and older cheaper GA aircraft usually do not have much in the way of computers in them. You have to do fuel burn calculations by hand based on how far you've flown and how the winds are blowing. You can then estimate how much fuel your plane is burning at a certain RPM. This is crucial in order to make sure you don't run out of fuel while flying, most older planes do not have a fuel flow indicator, and yes they do have fuel tank gauges, they never seem to accurately show your fuel levels. If the maps were distorted and inaccurate, we wouldn't be able to predict fuel burn correctly and you'd have a ton of pilots running out of fuel mid-flight on cross country flights, and it would be especially prevalent in Australia.

I'm both a private pilot, close friends with airline captains and I once was a very high mileage frequent flier (right when I was going through pilot training): There is no such thing as we're late, can you put us ahead of the landing queue. You can request routing shortcuts, however these days with GPS air routes that have lots of dog legs (using VORs) have been super seeded by quite direct GPS defined routes. It is in the FAA, Airline and environment best interest to route aircraft as directly as possible (even when the flight isn't late). This is particularly true for frequently flown routes between JFK, LAX, ATL, ORD metro area airports. Large transport aircraft have a COST INDEX in their flight computer. Changing the COST INDEX changes the cruising speed. When you are late, you can increase the cost index which will cause the aircraft to fly faster. When you have a strong tail wind on a long flight a pilot likely will change the cost index to 0 so the aircraft will fly as slow to use the absolute minimum fuel possible (COST INDEX is meant to signify that crew time costs money so going a little faster can be more economic overall so the same crew can fly a little more in a shift). Flight times have some fat in them. Rarely we landed as much as 15 minutes early on coast to coast USA flights, because nothing went wrong, specially when going against the jetstream when the jetstream was weak. In fact a few times we landed so early we had to wait a few minutes for a gate to be vacated to taxi to. So depending on how late a flight is, the padding plus an increase in cost index can fully make up for the lost time. Large transport aircraft can't fly much slower at optimal high altitude cruising levels. For instance a 737 NG normally cruises at Mach 0.80 and won't slow down below Mach 0.78 or speed up above Mach 0.81. The primary issue with long over ocean routes is ETOPS. A smaller twin (B737/A320) might be able to fly a 8 hour flight but it would need something like an ETOPS 300 rating to fly such a route (certified to fly 300 minutes after losing an engine right halfway through a flight, single engine flight is slower and uses more fuel). And never forget the winds. The jetstream exists both in the North and South hemisphere. They do vary over 100 knots (180 km/h) from winter (stronger) to summer (weaker). Long and medium distance flights will prefer taking the jetstream tail wind (flying closer to the equator than great circle) and avoiding the jetstream headwind (flying farther from the equator than a great circle). Of course that's the kind of nuance that flat earthers will never ever grasp.

Long term aviator here. First, I'm glad my many, many flights from Ascension to the Falklands never had to cross into the Northern Hemisphere; 13 hours going South all the way was quite long enough! And Port Stanley to Brazil we seemed to manage all in the Southern Hemisphere too. But as to airline routes and leaving late, there is a good margin of error built into the published arrival time to allow for contingencies such as delays and winds different to forecast. Also, when the pilots file their flight plan it will require them to follow certain specified way points, even trans-oceanic, which may not be in a straight line. If they can, they will once airborne ask air traffic for minor alterations to cut the odd corner or climb or descend if there is a better true airspeed v wind component solution to be had. They want to get there too and give the operator more time for the turnround. But airliners all tend to fly at much the same speed. This is because they generally follow airways and there is no overtaking. Therefore they tend to be designed to operate most efficiently at the same speed most guys fly.

@@wiredforstereo - Actually, I was reading an article some time back ago that was showing how airline speeds have actually slightly decreased in general. Nothing to do with the speed of sound however, but everything to do with fuel efficiency. Obviously the airlines are in it to make a profit, and thus they search for whatever savings can be had by cutting costs, within reason. When you are operating 5,000 or 10,000 flights in a day, cutting travel speed by even 50knots could equate to one hell of a lot of money, not just per day, but multiply that by 365 days in a years. I'm sure you reaching into the $millions of dollars savings at that point. The article I mentioned calls this out specifically as the biggest driver for the slightly reduced flight speeds over the past couple of decades.

Mechanical engineer with background and amateur interest in aviation here. You had good information, some of which could have been made easier with some aviation knowledge. 1st, thanks for the time and effort you put in this production. It is very informative. 2nd, I loved your visual about ground speed vs. airspeed. It shows how much of a difference wind makes to the trajectory and speed of an airborne object. There is something called prevailing winds or jetstreams where at those higher altitudes, there will be winds that blow at high speeds that are caused by the earths (sphereoid or disk. This is info, not an argument) rotation and allow going flights to be shorter than coming. I just looked up some flights quickly. From NYC to LAX it's 5hrs 55min and back its 5hrs 23mins. I'm assuming it's the same plane and everything else, so this is not a 'scientific' way of finding info. However, the principal remains; these winds affect a planes east-west ground speed more than north-south. 3rd, I may be remembering incorrectly, but I believe there is an international air directive (rule for flying planes) that says when flying over large bodies of water, the pilot MUST remain within gliding distance from the nearest land mass. This is for safety reasons. In the extremely unlikely case of a total loss of power, the plane needs to be able to make to or close to land. Therefore, aircraft over water rarely fly the 'perfectly shortest distance'. Again, thanks for the video. I hope these help the discussion!

As someone who worked 13 years in the Australian Airline industry, with the majority of that in airline network planning, I just shake my head at some of the claims over the shape of Australia, the shape of the earth, and how aircraft are scheduled and operated in general. Before I moved into route network development, I did reporting both internally and for legislative requirements externally. Part of this was reporting how many "seat kilometers" we flew, which was the agreed distance between 2 airports multiplied by the number of seats you flew between them. The Department of Transport and Communications (DoHC) at the time used to publish a book each year, which had the lat/long of every airport and the complete formula global for great circle distance (it varies on hemisphere). The lat/long was published because it did change occasionally. For example, when Sydney built its third runway, the centre of the airport moved SSE by just over a KM. The formula I had built into a spreadsheet, as well as the lat/long positions, and entering any 2 would give me the great circle distance (allowing for hemisphere) between these 2, and that was the industry-agreed distance. This was not only used for reporting, but also for planning, which would also include aircraft type, payload, waypoints, expected departure and arrival patterns (SIDS and STARS), expected out and in taxi times and winds aloft predictions (seasonal). This was used to calculate a) if the route was possible with the equipment type, and b) how much fuel was required (or if it was going to be payload restricted). If I haven't bored everyone enough, the final point is on ETOPS (Extended Range Twin Engine Operations). Australia is one of the only countries in the world where there is so much distance between airports that specific ETOPS requirements need to be met even on domestic routes. For example, back in the 1990's, one carrier had a fleet of 25 B737-300's, but only 8 were certified to fly between Melbourne and Perth direct. The direct track takes you out over the Great Australian Bight, which was too far south of Adelaide and Kalgoorlie in case of emergency. Flerfs will pick flights out that hug the coast and say "see, eRf iS pHLaT", when in fact it is likely an aircraft that is not or run out of ETOPS certification has conducted the service.

On 1 September 1983, Korean Airlines Flight 007 was shot down by a Soviet airforce pilot on the order of his superior officer, killing 269 people. There were no survivors. These innocent civilians were killed because KAL007 overflew Soviet territory while on a flight from New York City to Seoul via Anchorage, Alaska. The KAL pilot made a data input error while initializing the aircraft's inertial navigation system, which caused his flight path to deviate from the standard route that passes substantially east of Russian airspace. Most people condemned the Soviets for the attack, but at least one American publicly defended the shootdown. This was Pierre Salinger, a prominent Democrat and the former press secretary to President Kennedy. Salinger claimed the route from NYC to Seoul via Anchorage made no sense unless it was intended to fly over Russia on the way. The straight-line course was far shorter, he said, therefore the curved route through Alaska was very suspicious. As noted, Pierre Salinger had been a presidential press secretary, a job usually reserved for professional journalists, a profession not noted for extensive knowledge in the STEM fields. Consequently, Salinger used a Mercator map when formulating his theory. When the extreme inaccuracy of the Mercator projection, particularly in the high latitudes, was finally pointed out to him, Salinger withdrew his claims and retired from public life.

A common tactic I've seen time and time again from Flerfs is to produce something that they claim is consistent with a flat Earth and then claim it as proof, while ignoring the fact that it also consistent with the Globe model (often by misrepresenting the globe model.) Flight paths in the Northern hemisphere are an example. They ignore that a "straight line" shortest distance between two points on the surface of a globe follows a geodesic, or great circle. So, for example, a flight from the PNW of the US to Finland ( a flight my Mom and sister took back in the late '70s) passes over the Northern part of Greenland on both a flat Earth map and on a globe. So at best, it is a wash and not the evidence for a flat Earth they try and claim it as.

[@Hex___666]

They also ignore the fact that the opposite is true in the Southern Hemisphere, headings and distances are massively incorrect on a flat earth in the Southern Hemisphere.

[@Kyrelel]

The reasons why southern hemisphere flights make a stopover in the northern hemisphere: 1) Demand. If 300 people want to go from A to B and 300 people want to go from B to A, but only 100 people want to go A to C, a stopover allow at least 500 more people to travel on that route than a direct flight. 2) Operators: A to B may be operated by one airline, and B to C by another. Neither of these operators would want an extra flight operating from A to C 3) Fuel: A two-leg journey can be operated by a smaller (cheaper) aircraft, without the fuel capacity required for the flight A to C, by making a refuelling stop at B. 4) Safety: An aircraft must be able to land (on land) in the case of an emergency such as engine failure and will attempt to fly as direct a route as possible, whilst remaining close enough to land to make a landing.

When we got the new Tektronix computer, which could break down sailing routes trans-Pacific from say, San Diego to Hong Kong, why would the computer break down great circle sailing routes into segments all of which had different headings to continue taking the best course to your intended destination? Because after all, if the earth is flat you could sail that route using just a single compass heading. Then also, why is it that watch-standers on the top of the sail when underway surfaced can only see a few miles to the horizon? And then when at periscope depth why is it that your visible horizon through the periscope is so limited or as little as 3 miles perhaps when up atop the sail you could see over twice that distance?

[@Henoik]

Airplane navigation doesn't make sense on a flat earth. Most modern aircraft use inertial navigation systems (INS) along with GPS (where GPS is actually a secondary system). For an INS to work you need to be on a spinning globe, as it senses your place in the world based on gyroscopes... As for the delays, many airlines (especially those non-low cost) calculate some delay in their schedules. We can't really do much about our speeds. We operate on a Cost Index (advanced mathematical formula taken care of by the flight management computer) based on each airline's procedure and sometimes they even vary by route. Many airlines have a higher cost index during a delay, basically meaning they'll burn some extra fuel to increase the speed. But usually, that'll only increase our speed with mach 0.02.

Dave, there were a number of inaccuracies when you talked about aircraft operations. While aircraft are mostly flown by computer (autopilot), the route that the aircraft flies, which is better known as the flight plan, is filed before the aircraft ever gets into the air, and can change significantly between flights to accomodate the specific weather that is expected en route. Flight plans consist of flying a series of legs between waypoints, which are located with radio signals, or these days GPS. As you said, airlines are in the business of saving money, so they're never going to file a flight plan for an aircraft to intentionally go out of their way without a good reason. Another bit you got a bit wrong was around diversions, and long haul flights over water. One of the reasons that an aircraft may take a non-direct (on the globe) route is to ensure that it is always within range of appropriate airfields to divert to ('alternates') in the event of an emergency, and for two-engine airliners, which covers most commercial flight, this is based on the aircraft's rated limits of sustained flight with one engine out, for example if an aircraft has an ETOPS (Extended Range Twin Operations Approval) for 3 hours, then they can be no more than 3 hours flight time away from a suitable alternate airport at any point on their route, so their route is restricted by that limitation. The longest ETOPS rating is crurently for the Airbus A350-900, which is approved for 370 minutes (5.5 hours). ETOPS is actually the main reason that aircraft never flight directly over Antarctica, because to do so would exceed that approval. The higher ETOPS certifications mean that almost the entire globe is directly accessible with an appropriate aircraft, but it also means that in the event of an in-flight medical emergency, the plane may not be able to reach their nearest alternate airport for several hours. Similarly, a small single-engine aircraft, or a twin engine without an ETOPS rating may have to take a very inefficient route and add hundreds of miles to their flight path. Another aspect about flight efficiency that you may not be aware of is that modern turbofan engines are most efficient when run for long periods at a fixed speed - to fly slower is actually less efficient. Finally the reason aircraft don't fly faster is because on those large engines, the tips of the fan (in rotation) approach or even exceeed the speed of sound, creating shockwaves, which alter the airflow, and create drag.

I used to fly professionally, and you are right on with the flight thing. While some pilots (and airlines) will pull back the throttle, most pilots will put the aircraft at a decent speed to where they are going. My aircraft, the E175 would cruise around .72 - .76 Mach, but it should be noted, we routinely heard 737's (freaking Southwest) doing about .82/.83 on the radio, and they cruise at over .78 Mach. But the airlines will often schedule a flight for about, .72-.73 (our flights not Southwest) so that's what the route is scheduled by. So you're 100% correct, it was hard to make up time. Now, the tail number rarely matters when it comes to performance (rarely, we had one plane that would for some reason like pretending it was a rocket ship) as much as the aircraft. So that A380, most of them are only going to do about .75,.75 Mach at cruise. My guess is, if you made this recently, it was probably headwinds that caused it to be late, and it was just having a hard time catching up as A380's aren't that fast (NOTE: a 747 can do close to .85, almost .96 when empty such as Air Force 1). But the routes are also scheduled thanks to places to deviate to as well as what is most economical, so they will opt for as straight a path as possible, but will often times take a round about route thanks to ETOPS, although that isn't as much of a limiting factor as it used to be.

"Let's use a flat 2D projection with known distortions to 'disprove' a 3D globe" And they don't even realise why that gets laughed at. They literally just disprove one flat earth model. And no modern flat earther will provide an actual flat map, because each flat earth map is only useful for one specific argument. Every flat map can be debunked by many methods, while on an actual globe, every single situation just makes sense.

Even among flerfs, Terry ain’t the sharpest tool in the shed. He once posted a video claiming a fishing boat in the Bass Strait was turned back by a naval ship because it was too close to the 60 thparallel. I commented saying he doesn’t know how to read a map and that the Bass Straight is between Australia and Tasmania, a place where people live. He deleted the video.

[@smaakjeks]

The flerfers are implying that a pilot wouldn't be able to understand their aircraft well enough to know when it flies 2.5x slower/faster. Do the controls of the plane know where in Australia they are and where they are going such that they limit how much thrust they give for the same speed setting of the levers? Does the sentient plane also gradually dump fuel one way in Australia but not the other, so that the amount of fuel needed comports with globe routes? Or do the plane and the tanker truck conspire together to lie to the pilot and the ground crew about how much refueling is being done? Tanker truck: This is how much fuel we're giving the plane for this north-south flight, you guys, for totes. Just as much as when we go east to west! [WINKS AT PLANE] Plane: Oh, yum, exactly the same amount of fuel, how sensible and logical, given that it's the same distance, glug glug [WINKS AT TRUCK]

Qantas, QF14, left Buenos Aires, Argentina, South America at 12:44 pm local time on Tuesday, October 5 2021, then flew south, CROSSED part of ANTARCTICA, and arrived in Darwin at 6:39 pm local time on Wednesday, October 6. The journey was entirely in daylight. Look it up. It was almost all over ocean except part of Antarctica and then the Australian mainland. The flight an Australian government organised Covid repatriation flight for 107 Australians, set two Qantas records in the process: longest distance covered (15,020 km or 9,333 miles) and longest time in the air for a commercial flight (17 hours and 25 minutes). The reason it went to the capital of the Northern Territory, Darwin was because there was a huge Covid quarantine facility built there in the nearby desert. There have been thousands of regular flights non stop between Sydney and Perth Australia and Johannesburg South Africa since the 1970s. All across the Southern ocean. As well as Sydney to Lima Peru across the Pacific, non stop. To argue that they don't exist is ludicrous.

[@TheDivegeek]

A similar powerful disproof of flat Earth theories is the existence and times of sailing circumnavigation races. These all go to the Southern Ocean and do most of their actual going around there, because there's no land in the way and because it's a shorter trip (though they are required to cover enough distance to have circumnavigated at the equator, if that were possible; they get the additional needed distance from north/south travel). But on a flat Earth with the north pole at the center, a southern circumnavigation would be a huge distance, and while these are often very fast sailboats "fast" is a relative term; most have maximum speeds of no more than 15 mph, and even the fastest can only reach 50 mph, and only under ideal conditions). I suppose all of those sailors must be part of the conspiracy.

[@bigJovialJon]

Why would the airlines change the speed of their planes to make the distances match globe distances? Wouldn't an airline want to have their flights fly at whatever speeds are the most profitable?

What i wonder is: Why would a company that is striving for maximum profit go out of its way slowing down airplanes and reduce passenger volume to keep up a lie? That would cost them huge amounts of money they could get if the planes just go their most efficient, faster speed. Companies lie to maximize profit, not to reduce it.

[@jerry2357]

Hi Dave, you should do the day-night mercator map to azimuthal equidistant projection operation, using a day-night map for northern hemisphere winter, e.g. 21st December. Then ask the flerfers how a point sun can illuminate a flat plane in that way.

[@OldManTenno]

How to recognise flat earthers on a flight ? they’re always leaning in their seats cause they think the plane is turning the whole flight !

[@jeffbeck8993]

They also bob their heads forward and backward from time to time due to the pilot nosing the aircraft down to prevent flinging off into low Earth orbit. 🤣

"flat earthers" use a map that's 00.00% accurate ?? .... NOW THAT'S FUNNY !!

[@ThomasJackClark]

Dave, I am not a flat earth person, but I do want to point out an incorrect statement that you made. At approximately 11:35 in the video you said that if there is no wind the airspeed and ground speed of a plane would be the same. You made this statement in reference to the stall speed of the airplane. The problem with this is that the stall speed has to do with indicated airspeed, not true airspeed. Indicated airspeed is measured by taking the difference between static pressure (the pressure of the air at that altitude) and the pitot pressure (air pressure measured by a forward facing tube [the pitot tube]). Indicated airspeed measures what the airfoil (wing) “feels” as it moves through the air, that generates the lift. As the altitude increases the air becomes less dense and the airfoil (and pitot tube) “feel” less airflow so it generates less lift (and a lower indicated airspeed) at the same true airspeed. To use your 250 knots example: an indicated airspeed of 250 knots would be a true airspeed of 304 knots @ 10,000 feet, 372 knots @ 20,000 feet, 462 knots @ 30,000 feet (air temperature and humidity have effects on these measurements, so the figures I gave are general figures without compensating for those factors). Trying to simplify this I would say: indicated airspeed directly relates to stall speed, true airspeed directly relates to ground speed, between the two are a lot of complicated calculations.

[@Ianshandle999]

I have flown these flights in Australia. Whether you go north/south or east/west it takes about the same time, plane flies at normal speed, and you cross Ayers Rock in the middle of a straight flight path. Flat earther proof debunks flat earth as usual.

[@pinkkfloydd]

"The shortest distance is always a straight line." Yeah, in basic Euclidean geometry. Wait til he learns that spheres have different geometries, like how in different geometries, the angles of a triangle can add up to more than 180 degrees.

[@RobertHollander]

Around 11:34, you say that if there was no wind, the airspeed and ground speed would be equal. That isn’t exactly correct because you are referencing this in the same conversation as stall speed. The stall speed of an aircraft is based on INDICATED airspeed. As a plane flies higher, the INDICATED airspeed will become increasingly less than the TRUE airspeed (TRUE airspeed being the INDICATED airspeed corrected for installation error, temperature, and pressure altitude.). This is one of the many technicalities associated with aviation that people probably wouldn’t know unless they are pilots, which I happen to be. (As a side note, the typical stall speed of a commercial airliner is from 100 to 130 knots indicated airspeed, not 250. But keep in mind that 130 knots indicated airspeed may actually equate to a true airspeed of 250 knots depending on the temperature and altitude). The stall speed and pressure altitude of an aircraft begin to converge as a plane flies higher leading to a flight configuration know as "coffin's corner."
