No, the shuttle weighed 165,000 pounds when empty, or 73.6 tons. A satellite weighing 6 tons is roughly one twelfth of this, and will therefore require approx one-twelfth of the thrust, approximating to a fuel requirement of one twelfth.

You can't just compare mass of the spacecraft; it also depends on the required orbit.  Geostationary orbits require a much higher altitude and speed.  Spacex's Falcon Heavy, for instance, can theoretically put a payload of 63,800 kg into low earth orbit (like the shuttle and most earth-observation satellites)), but only 26,700 kg into geostationary orbit. 

And any craft which goes into space is, by definition a "spacecraft".

Tom,

Is there something intrinsically false about instructional material aimed at individuals with an age-range including high school students, college students, married people, voters, car drivers and private pilots?

And if its target age-group also includes "children", how does that devalue its merit?

Flat Earth Theory / Re: Gravity - measurement and applications

Are we missing the elephant in the room here? 

This thread has moved on ("gravitated", if you will) to discussion of hypotheses for the documented stable variations in gravity in different parts of the Earth under a RE model.  There is no sign of agreement, but there is at least one hypethesis. 

What is the FE/UA hypothesis, if the whole Earth is accelerating at the same rate?  Are some parts being left behind?

Am I missing something here? 

"Oh-oh failure" occurs 30 seconds after launch, impact at 60 seconds; 30 seconds to descend. 

The vehicle tumbles to earth, lets give you the benefit and say no aerodynamic drag, accelerating at 9.81 m/s/s (gravity, or UA, as you will).  Lets give you some more benefit and say "oh-oh failure" occured at 20 seconds (speed of sound to hear the impact) gives us 40 seconds of descent, at 9.81 m/s/s. 

Using a standard acceleration formula with this time and acceleration gives us a dome-impact altitude of less than 26,000 feet. 

How does this fit with typical airliner altitudes of 30,000 to 40,000 feet? 

Is that why airliners go mainly "sideways" and less "up"? 

Do airliners also need a permit from the Space Police?

J-Man:  "Tumeni give us hocus pocus speak. To get a permit for rockets you must not encroach on the dome, ....."   

Can you apply for this permit on-line, or do you have to go to the Space Police office?

Flat Earth Investigations / Re: NASA claims Flat and Fake Apollo Missions
« on: September 11, 2020, 10:33:20 AM »
I'm a former contractor for the UK Ministry of Defence (MoD). 

I've overheard conversations between people in the MoD who appear convinced that the Earth is a globe. 

This leaves us at something of an impasse doesn't it?  (Perhaps it would help if I made a video)?

Flat Earth Media / Re: International Shipping Agent
« on: September 06, 2020, 10:26:14 AM »
I think this thread has been confused from the outset by us discussing different definitions of "shipping". 

My interpretation of the OP was its concern with "shipping"; sending goods by a parcel/freight service using road, rail, air, sea or whatever, (eg DHL, FedEx).  This is typical going to be from consignor to hub, to hub, to consignee.  In this context, shipping (parcel service) is going to depend to some extent on geography, but geographical priorities will be way below the commercial-drivers of politics, population density, location of financial hubs, value of the goods, urgency and differing customs/tax regimes.  This is unlikely to infer much about the shape of things. 

On the other hand, some people have interpreted it as "shipping"; big boats sailing across oceans between seaports, eg Exxon, MSC, Maersk. The decisions about which ports to use are going to be driven by the same commercial-drivers as shipping (parcel service), but once the goods are on a big boat it is just going to take the fastest, safest route from port to port.  These routes are going to say quite a lot about distances, and infer a lot about the shape of the Earth.

1.  At 35 km, the camera is about 0.5% further from the centre of the earth than it is at the surface.  How much better perspective is this supposed to give us? 

2.  Any lens with a focal length <infinity will distort the image to some extent.  And what is a "non-fisheye camera"?  Focal length?  Can I buy one?

3.  Styrofoam is a well proven straight-line reference medium.  Oh, I'm sorry, I'm thinking of stainless steel.  Apparently, styrofoam is NOT a well proven straight line reference medium. 

4.  Garlic?  Bread?

Flat Earth Theory / Re: Center of gravity of objects on a flat earth

You need to ask yourself how 100kg-kid is "... supported above the ground".  He isn't suspended by levitation, he's only there because he's an integral part of a rigid ASSEMBLY comprising him, the 50kg-kid, and a beam, all attached to the planet by a pivot.  We assume that the beam itself is symmetrical and its mass is evenly distributed, so the COM of the ASSEMBLY is to the right of the pivot, because that's the end the 100kg-kid is sitting.   

If the planet accelerated up at 9.81 m/s/s, that force is going to be felt at the pivot of the ASSEMBLY.  The inertia of the ASSEMBLY acts at its COM which to the right of the upward accelerating force.  The 2 forces form a couple which rotates the ASSEMBLY clockwise until the planet hits 100kg-kid's butt, at which time the accelerating force is now distributed to both sides of the COM, via the pivot and his butt. 

Stop thinking of him in isolation.  He's just a part of something bigger. 

And have you noticed I've stopped calling him fat-kid.

Some discussed possibilities are generally that the Bi-Polar model is true or that the airliners are taking advantage of anomalous winds in the South:

Anomalous Winds over the Southern Oceans

Winds over the Southern Oceans are reputed to be of an anomalous nature, as compared to winds in the North.

Australian Antarctic Division

http://www.antarctica.gov.au/magazine/2001-2005/issue-4-spring-2002/feature2/what-is-the-southern-ocean

  “ The Southern Ocean is notorious for having some of the strongest winds and largest waves on the planet. ”

BBC Earth

http://www.bbc.com/earth/story/20151009-where-is-the-windiest-place-on-earth

  “ There are huge belts of wind caused by the uneven way the Sun heats the Earth's surface. 30° north and south of the equator, the trade winds blow steadily. At 40° lie the prevailing westerlies, and the polar easterlies begin at around 60°.

Ask any round-the-world sailor and they will quickly tell you the stormiest seas, stirred by the strongest winds, are found in the Southern Ocean. These infamously rough latitudes are labelled the "roaring 40s", "furious 50s" and "screaming 60s". ”

Journal of Geophysical Research

https://agupubs.onlinelibrary.wiley.com/doi/full/10.1029/2003JD004179

  “ The Southern Ocean is a vital element in the global climate. Its circumpolar current plays a crucial role in the global transport of mass, heat, momentum, and climate signals from one ocean basin to another. Moreover, the Southern Ocean hosts the strongest surface winds of any open ocean area, fostering strong heat, moisture, and momentum exchanges between the ocean and atmosphere. However, the Southern Ocean is tremendously undersurveyed by traditional observation methods because of the remoteness of the area and rough environment, causing the largest data gap of global oceans. ”

CIA World Factbook

https://www.cia.gov/library/publications/the-world-factbook/geos/print_oo.html

  “ the ocean area from about latitude 40 south to the Antarctic Circle has the strongest average winds found anywhere on Earth ”

The SH flights seem to disappear from radar in interactive flight maps, but Jeran noticed an anomaly on an interactive flight map showing that the true air speed was much faster than the ground speed on a SH long haul flight, on areas where the data appeared.

See around the 1h32m mark of the following video:

https://youtu.be/O6tPdNKPmek?t=5502



Yes Tom, the speeds fluctuate.  And did you watch the altitude?  Up and down by 20,000 feet within seconds. 

I was watching Sky News last week while they interviewed someone from home (in the current Corvid-19 situation) by Skype or Zoom.  At one point his face froze, but you could still hear him speaking!  Do we suspect a sinister conspiracy?  Greenscreen?  No; we just assume loss of data. 

I know its the 21st Century and all that, but if they can't maintain a coherent conversation for 4 minutes beween the Sky studio and somebody's dining room in Croydon, is it surprising if the same thing happens occasionally with 15 hours of data from 40,000 feet above the Southern Ocean? 



194
Yes, its a 50 minute video of a 15 hour flight so it could be a fake. 

If a passenger made a 15 hour video of the 15 hour flight, at some point he is going to use the bathroom.  Ah haaah!.  Lack of continuity!  Could be a fake!  And who in their right mind is going to sit through a 15 hour video of a seat-back anyway? 

The fact is, as iamcpc is well aware, this was discussed in depth at another thread; 

https://forum.tfes.org/index.php?topic=15877.100

which demonstrated that just like other long-haul, these flights are taking place several times a week, with passengers on, departing and arriving at more-or-less the scheduled times, in both directions, without diversions or in-flight refuelling, and without having to wait for a freaky wind.

It's the same concept as airlines.  Shippers use Hubs, track a package on FedEx from Texas to California and it goes through Memphis TN.  No mystery here.

That would still discredit the claims that shipping routes prove RE.

The OP claimed that shipping routes discredit RE.  They don't.

Flat Earth Theory / Re: Center of gravity of objects on a flat earth
« on: August 20, 2020, 04:24:35 PM »
Like IAMCPC said. 

Don't get hung up on the name "Centre (or Center) of Gravity", just because it has "gravity" in the title.  Engineers and scientists use "Center of Mass". 

It doesn't matter whether the acceleration is due to gravity, ball hit by a bat, bullet in a gun, or something on the floor of an aircraft pulling "g".  As long as the accelerating force is distributed around the Centre of Mass (C of M) it's stable. 

In the teeter totter (I'm assuming Brit English see-saw), lets say Skinny Kid is on the left, Fat Kid on the right.  (Can I say Fat kid?).  The pivot is in the middle, C of M is to the right-of-middle. 

If the planet is accelerating up, the force is applied to the pivot, which is left of the C of M. 

If Earth's Gravity is applying a down-force to the C of M, the reaction is felt upwards at the pivot, which is, again, left of the C of M. 

Either way, the 2 forces are not aligned so the outfit rotates clockwise until Fat Kid's butt hits the planet, at which time, C of M is now supported by the pivot and his butt; stability restored. 

Gravity? Acceleration?  Doesn't matter.

First, you say you have documented instances of altered records.  You haven't. 
Will you please promise that you will check history on this particular flight for the next couple of days and advise the Forum when it gets altered?

You are right. I didn't realize that, when i clicked the link, it shows the most recent BAW6B flight. Because I clicked the link the next day the flight path that I saw was from the following day. Human error.

In answer to your question I'm not sure I understand.  You want me to propose a flight which supports one of 2 FE models?

Let's start here. Which, of the two proposed FE models that I have shown, do you think most closely resembles the world you live in?



First of all thank you for acknowledging that you had misinterpreted your interrogation of the Flight Record; I think you will earn respect for that from the other posters. 

On the map thing, I'm sorry if it sounds like a cop-out, but neither.  (Possibly the Polar, but only because we were looking at a Northeren Hemisphere question. If we were discussing a flight from New Zealand to Chile, the Polar would be useless). 

The problem with all of these projections is the distortion of the image, generally the further from the centre of the Polar Map, or from the equator of the Mercator Projection, more distortion is introduced.  Look at Australia in the Polar Map; if it was that long and thin, don't you think the Aussies would have noticed? 

Its like if you went to the barbershop and he asked where you want him to stand when he cuts your hair.  If he stands in front of you he can see your fringe, but round-your-ears is distorted; he needs to see these from the side.  And so on.  Its inevitable if you try to project a 3D object onto a 2D plane.  Thats why its called a projection. 

For maps, personally, I use Google Maps in the Globe mode.  You get your area of interest centre-screen and its going to show the minimum amount of distortion, but distortion is still there and increases as you look towards the edges of the image.

Quite agree that BAW6B (aircraft reg G-ZBKI) did not fly over Greenland on 26/27 July.  I don't think anyone claimed it did. 

Yes they did. They did it here:
[EDIT 2] And now, London time 12:28 (BST) BAW6B has neatly crossed the tip of Greenland and most of the North Atlantic, just approaching the coast of Ireland.  Scheduled to arrive at Heathrow 14:05. I live underneath the flight path so I will be able to see it come in.

In any case, check the history for this aircraft and please come back and tell everyone that it crossed Greenland.  Or not.  And remember, we are talking here about G-ZBKA on 27/28 July. 

The website indicated that it crossed Greenland. Unfortunately there have been instances, which I have already documented, in which the flight was shown as having crossed Greenland just to have been deleted and replaced with a flight which has not crossed Greenland.
Now that I have answered your question, Can you answer mine? What is a flight that we can take in which the path that we fly would support one of the two presented FE models?

First, you say you have documented instances of altered records.  You haven't.  You've looked at the most recent flight and thought that it referred to previous flights.  Have you actually looked at the history on, say FR24?  (You'll probably have to look under the alternate Flight Number of BA286).  Over the past 12 hours we've observed BAW6B/BA286 on FR24, identified it by registration, and one of today's posters has actually seen it through binoculars.  Will you please promise that you will check history on this particular flight for the next couple of days and advise the Forum when it gets altered?

In answer to your question I'm not sure I understand.  You want me to propose a flight which supports one of 2 FE models?  How can I do that when I personally don't support any FE model?

You do understand that a Flight Number is not unique? 

How many flights from SF to london have flight number BAW6B which arrived today? Both of these show a flight path not over Greenland

https://flightaware.com/live/flight/BAW6B/history/20200727/0245Z/KSFO/EGLL
https://www.radarbox.com/data/flights/BA286/1439853660

On the live tracker it showed the flight going over greenland and on this website it shows the flight not going over Greenland. It's funny how the live tracker gets "deleted" and replaced with the new flight path.

Most flights on popular routes take place several times a week, under the same Flight Number.  So you need to specify which date you are talking about for a particular Flight Number.  If you think the "flight path changes after the plane lands", then you are looking at the same Flight Number on a different day.


I'm talking about the BAW6B which was in the air today referenced earlier in this thread which left SF 7/26/2020 and arrived in London 7/27/2020.


The route will be different each day.


Can you find me one nonstop flight from SF to London  which flies over Brasil?

According to https://flightaware.com/live/flight/BAW6B/history the flight from SF to London never passed over Greenland. Even though the live tracker shows the flight over Greenland. Can you send me one link to a completed nonstop flight between SF to London in which the flight tracker shows the flight passing over Greenland?


It might be worth it to add these inconsistencies to the wiki because something is clearly off.

Quite agree that BAW6B (aircraft reg G-ZBKI) did not fly over Greenland on 26/27 July.  I don't think anyone claimed it did. 

Nor on the day previous, 25/26 July (aircraft reg G-ZBKS). 

However, on 23/24 aircraft reg G-ZBKB did cross Greenland. 

At the moment (about 08.00 UTC on Tuesday 28 July), BAW6B is being flown by Dreamliner G-ZBKA.  It is over Baffin Island and looks to be headed for Greenland on its way to LHR, where it is estimated to land at around 12.30 UTC.  If you read this in time please follow the flight on a website of your choice. 

In any case, check the history for this aircraft and please come back and tell everyone that it crossed Greenland.  Or not.  And remember, we are talking here about G-ZBKA on 27/28 July. 

And as for Brasil .........
