Again, I still don't understand exactly how wanting someone who has been charged with multiple crimes to have their day in court is wanting to "eliminate due process;" much less how having that same person entirely avoid having their day in court by being elected president and then abusing their office to make their legal problems go away is totally fine.

They don't. Flights are canceled all the time, especially long haul flights. See this quote by travel writer Maggie Teneva:

“Long-haul flights are often associated with long layovers and delays or cancellations.”

If there are unexpected changes to the jet stream or winds mid-flight, a non-stop flight might even stop for fuel:

“ Dozens of Continental Airlines flights to the East Coast from Europe have been forced to make unexpected stops in Canada and elsewhere to take on fuel after running into unusually strong headwinds over the Atlantic Ocean.

The stops, which have caused delays and inconvenience for thousands of passengers in recent weeks, are partly the result of a decision by United Continental Holdings Inc., the world's largest airline, to use smaller jets on a growing number of long, trans-Atlantic routes. ”

Per ETOPS, plane flight routes are required to be in vicinity of airports or landing strips for unexpected stops like that. Even long haul flights over oceans need the capability to make detour routes to islands with landing strips in case something like the above happens. The US Military is even known to maintain landing strips on certain uninhabited islands in remote locations for ETOPS purposes.



The quote from Maggie teneva (who she?) is simply a throwaway line at the end of an article about entertaining your kids on longhaul. 

The "stopping for fuel" link doesn't go anywhere. 

The Continental Airlines example is undated, has no reference, and (if true) sounds like poor planning by  the airline in not using aircraft with apprpriate capacity/range.   

ETOPS is not a restriction; it is a relaxation of previously existing routes that require aircraft to route within 1-hour flying time of a suitable diversion airfield.  In the case of the Airbus A350, this can now be extended to 5hrs 30min at single engine cruise speed (frightening but true), meaning that only Antarctica is off limits (unless, of course, one of the ice-runways is the destination). 

The USAF, being outwith ICAO regulations, is not limited by ETOPS.  The United States maintains "landing strips on certain uninhabited islands in remote locations" for military operational, security and diplomatic purposes. 

Aircraft often divert from route for reasons of security, medical or technical emergency, but beyond the apocryphal stements you have made, I challenge you to identify a single recent occurance made purely for a splash and dash.  Any commercial aircraft diverting from its planned route purely for a fuel stop would find its captain and dispatcher having a series of one-way conversations with management. 

And yes, jetstreams are a perpetual phenomenon, but no they are not alway at the extreme stengthsyou suggest, and almost without excdeption are a west-to-east direction.  Apart from local eddies there is absolutely no, general, assistance, anywhere on Earth, to westbound travel. 

Your statement "Flights are canceled all the time, especially long haul flights" is simply untrue.  For example, I've just looked at data on FR24 for LATAM's Santiago-Melbourne service LA804/805; run with a Boeing 787 Dreamliner.  The service operates 3 times a week in each direction and between 15 Feb and today, 12 weeks, 36 planned return trips; one cancellation.  And the flight times:

Santiago-Melbourne; quickest 12.55 (16 Feb), longest 14.45 (1 March). 
Melbourne-Santiago; quickest 11.38 (12 March), longest 12.35 (23 March). 


Action80;  You haven't said when your flight was, or whether it was over land or sea, but its not unusual.  Over land there is normally good radar coverage and separation is normally monitered by ATC controllers.  Oceanic; aircraft are cleared to fly a route between specific waypoints, but the principal separation is made by altitude.  Separation used to be 1000feet but for the last 20 years or so this was reduced to just 500feet, with a strict regime of altimeter-inspections and aircrew compliance.  At about a mile, a 500foot difference would probably be indistinguishable.

The vaccine was created to modify political views and eventually control the mind; ironically, the people most likely to take the vaccine were the least in need of mind control. They were already subservient to big brother. You wouldn't notice any difference in their behavior before and after taking the vaccine.

And those most needing identification are the rebels.  The outliars.  The lone wolves.  And the ones most likely to complain and not wear facial ID blocking masks.

Why are westbound transatlantic routes located hundreds of km away from eastbound routes?


I would say it is a good thing the routes are spaced so far apart.

I can remember traveling to Mexico City at 14 and the captain came over the radio, informing the passengers to look out the port windows to see another jet passing in the opposite direction. It is rather strange and frightening to see another jet pass by so closely at 35k ft.

You're talking about the jetstreams as being a constant phenomenon.

Correct. The jetstreams are present year-round.

https://www.popularmechanics.com/science/environment/a9181/how-the-dual-jet-stream-sparks-this-weird-summer-weather-15634917/

"The jet stream is a year-round feature of our atmosphere, but the double jet stream phenomenon is more common in winter."

https://www.rmets.org/metmatters/jet-stream-weakening

"In the UK, we feel the influence of the polar jet stream (which is also sometimes called the ‘mid-latitude’ or the ‘eddy-driven’ jet stream), which forms due to the difference in the temperatures between the pole and equator. On its northern side lies colder air, and on its southern side warmer air – so its position is important for what type of weather we experience in the UK. It waxes and wanes with the seasons, being strongest in winter, but is a year-round phenomenon."

https://en.wikipedia.org/wiki/Jet_stream

"The northern hemisphere polar jet flows over the middle to northern latitudes of North America, Europe, and Asia and their intervening oceans, while the southern hemisphere polar jet mostly circles Antarctica, both all year round."

They aren't, they are variable, in location, direction and velocity.  Like I said, its just a wind.  If its above 60 kts, as you say, they term it a jetstream, but its still just a wind. 

And you are absolutely correct that favourable jetstreams (like other winds) are exploited for the purpose of speed and economy, but if the jetstream is absent, or unfavourable, the flights still occur.

Just look at the post-Covid-resurrected Qantas/LAN services between Chile and Australasia; they take place on schedule every time, eastbound and westbound.  They can't be that anomalous can they? 

Now try Googling Air France flight AF174 on 8 May.  (Or here's a link);

https://www.flightradar24.com/data/flights/af174?utm_campaign=website&utm_medium=email&utm_source=sendgrid.com#351eba3d

Airbus A350 F-HUVC departed Paris CDG as AF174 for Mexico City but developed a problem over Newfoundland and returned to CDG.  Flight tracking data shows that the return leg was performed almost completely along the same route and at a similar altitude as the outbound leg.  Pretty dumb with a 300mph wind wasn't it, or maybe the airline actually knew the windspeed?

The Jet Stream can change in nature within hours. This is why those non-stop flights stopped for fuel in the previous quote I gave. Those planes didn't take off knowing that the winds would be unfavorable. Planes have a network which tracks the Jet Stream to follow the best path in real time. If that was the path it took, then it is simply because the flight logistics people determined that it was the best path at that specific time.

https://en.wikipedia.org/wiki/Jet_stream

"Jet streams may start, stop, split into two or more parts, combine into one stream, or flow in various directions including opposite to the direction of the remainder of the jet."

In this case, the jet stream probably just moved out of the way and the plane had enough fuel in its wings to take a long trip back, or there was a favorable path at a lower altitude.

Most typically, the planes take different routes on the return trip:

Why are westbound transatlantic routes located hundreds of km away from eastbound routes?

Looking at flights between NY and London (click to see route):

BA 185 (EGLL - KEWR)
United 941 (EGLL - KEWR)
United 16 (KEWR - EGLL)

The FlightAware anticipated routes are quite similar in both directions, but the actual routes for past flights are really remote from each other:



The two westbound routes are either 800 km north or 1,000 km south of the eastbound route (the dotted line shows the shortest path).

Why are the two westbound routes different and so remote from each other? Why this difference of about 1,800 km?

Why BA 185 route seems to be composed of two arcs?

Did the pilots changed their mind in flight because of the jet streams? Is it related to ETOPS constraints, or alternate airport at Santa Maria? or something else?

A jetstream is just a wind, and I accounted for it in my calculation.  A look at any jetstream map will show that they are predominently westerly in the southern hemisphere, which corresponds with my previous statement and, if it is assisting the eastbound flight will it not be hindering the westbound which is occuring simultaneously and at similar latitudes? 

We've also done Jeran's thing before.  Simultaneous to the "supersonic" speeds is a series of altitude changes which an F-16 would struggle with.  Its just a batch of missing data on aircraft position; when it recovers the position data it integrates the delta-position over time to determine speed.

The speeds you provided for the Southern Hemisphere flights were too low. You stated "40 kts acting as a headwind hampering LAN801 and assisting LAN804". Jet streams are far faster, and we know that long haul flights take advantage of the Jet Stream.

https://skybrary.aero/articles/jet-stream

"To be considered a Jet Stream, the accepted minimum speed limit is 60 knots. The speed of the Jet Stream is typically 100 kts (nautical miles per hour) but can reach 200 kts over North America and Europe in the winter. Speeds of 300 kts are not unheard of, particularly over south-east Asia."

Commercial flights would fly at the the plane's cruising speed + the Jet Stream speed. See this article from a Northern Hemisphere event over the Atlantic Ocean:

https://www.cnn.com/travel/article/jet-stream-flights-speed-of-sound/index.html

'In February 2019, a Virgin Atlantic plane flew at 801mph from Los Angeles to London, reaching its top speed over Pennsylvania thanks to a 200mph jet stream – although it slowed down to a mere 710mph once it hit the ocean. The aircraft – a Boeing 787 Dreamliner – usually has a cruising speed of around 560mph. Virgin founder Richard Branson described it as flying “faster than any other commercial non-supersonic plane in history.”'

Rowbotham's original society solved the sinking ship.
Did it, though? He spends some time in ENaG claiming that things like ladies dresses disappear bottom first on a flat path, which they don't. And then he claims that ships which have gone over the horizon can be "restored", which they can't.

All of this is true of this effect though, and you have even admitted that the effect exists before in past conversations. See this past admission from 2022 from you:

Quote from: AllAroundTheWorld
But in any case, your "experiment" simply demonstrates the part I already wrote in bold above. The very thin hull in your picture will become hard to resolve at a certain distance. And yes, in that case optical magnification could "restore" it. But the reason it can be "restored" is that it isn't hidden in the first place. It isn't behind anything, it just becomes difficult to discern at a certain distance.

Which is exactly what Rowbotham is describing in Earth Not a Globe. When bodies are smaller than 1/60th of a degree they become lost to optical resolution, and are beyond perception. So, you were wrong. This effect does exist and it is reversible with optical zoom.

The experiment we discussed in that thread is still available for you to perform here:

Lady Blount's society collected the professional surveyor and railway proofs.
Did they? Well where are those then? I looked her up and found something about some photo they took. It's here:
https://en.wikipedia.org/wiki/Elizabeth,_Lady_Blount#/media/File:Blount-photo-bedford-level.jpg
What the hell is that supposed to be?!

The railroad references are here: https://wiki.tfes.org/Railroads

Yes, Lady Bount also verified Rowbotham's water convexity experiments with the then-new technology of long distance photography.

https://wiki.tfes.org/Bedford_Level_Experiment

Quote
The Old Bedford Level was the scene of further experiments over the years, until in 1904, photography was used to prove that the earth is flat. Lady Blount, a staunch believer in the zetetic faith hired a photographer, Mr Clifton of Dallmeyer's who arrived at the Bedford Level with the firm's latest Photo-Telescopic camera. The apparatus was set up at one end of the clear six-mile length, while at the other end Lady Blount and some scientific gentlemen hung a large, white calico sheet over the Bedford bridge so that the bottom of it was near the water. Mr Clifton, lying down near Welney bridge with his camera lens two feet above the water level, observed by telescope the hanging of the sheet, and found that he could see the whole of it down to the bottom. This surprised him, for he was an orthodox globularist and round-earth theory said that over a distance of six miles the bottom of the sheet should be more than 20 feet below his line of sight. His photograph showed not only the entire sheet but its reflection in the water below. That was certified in his report to Lady Blount, which concluded: "I should not like to abandon the globular theory off-hand, but, as far as this particular test is concerned, I am prepared to maintain that (unless rays of light will travel in a curved path) these six miles of water present a level surface."
—The Zetetic Website

Near the surface of the water, for at least the span of six miles, the light created a path which contradicted Round Earth Theory.

EA and UA are admittedly pretty good explanations for certain observations BUT they are just that.

A hypothesis typically does not have supporting evidence. However, the pages show that there is supporting evidence for celestial-scale, and possibly celestial-specific, bending of light.

https://wiki.tfes.org/Electromagnetic_Acceleration



This is an issue with your way of enquiring. You form a theory which explains observation rather than forming a hypothesis and then making observations which test that hypothesis - which then becomes a theory as observations build confidence. I know this is deliberate, and working the other way around could lead to the same conclusions. The issue though is when observations are presented which show your theory to be wrong you just claim they're wrong/flawed/fake. That's not a way to make progress.

Incorrect. There are observations to test the EA hypothesis of large celestial-scale bending.

If you ask me what is happening on earth thousands of miles away, there will be less research there. The total world model is a topic for the next generation of FE to figure out.
Is it, though? There are flat earthers all around the...disc, right? And we have instant communications now.
There are surely ways you can do large scale experiments reasonably cheaply. I'm sure you could club together and get a ticket for a Santiago to Sydney plane ticket, a FE person on that flight could gather a load of data which would help you advance things.

People sitting in a plane have a difficult time telling how much the winds and the jet stream are adding to the journey. Planes have a hard time determining their true speeds because they are propelling themselves in pockets of fluids which itself is traveling through larger scales of fluids. Wind-intake odometers for planes are notoriously inaccurate. Comparing yourself to Lat/Lon coordinates would also change your speed depending if you are assuming an RE or and FE which has different spacing between the coordinate points. There needs to be an independent method of speed determination.
