Flight over the North Pole:

Please read the FAQ (https://wiki.tfes.org/Frequently_Asked_Questions)
Q: "There are many pictures on the internet and in other media depicting the earth as being round. Why do these not disprove flat earth theory?"
A: "In general, we at the Flat Earth Society do not lend much credibility to photographic evidence. It is too easily manipulated and altered. ..."

A youtube video is no proof that flights above the North Pole are possible. This is not only true for "my picture proves that the earth is round"-claims. Many youtube videos exist that state ridiculous claims...

....They have a very definite range of speeds in which they can operate at altitude. An airliner can't maintain 30k feet and fly at 200 mph. There is a hard vMin at all altitudes. If you drop below that, you fall out of the sky. Educate yourself.

You are right, not all air speeds are possible. Therefore, you can not fly over the north pole / fly realy far north, otherwise you would "fall out of the sky".

You will find a GPS receiver works well by a plane window giving the speed and the map ties up with the land observed below.

Please read the wiki on conspiracy (https://wiki.tfes.org/The_Conspiracy). GPS was installed by the US governement, which is also responsible for the NASA conspiracy.

Flat Earth Theory / Re: Gravimeter

« on: November 29, 2017, 03:48:21 PM »

A gravimeter is an accelerometer. It measures acceleration. The average acceleration of earth is 1 Gal (by definition) or 30.48 ft/s^2. However this acceleration is not constant over the plane(t). Some areas exhibit slightly higher acceleration, e.g. the acceleration at the bottom of the Mariana trench is approximately 100 mGal lower than the average. This effect is called "Gravity Anomaly" (it should be "Acceleration Anomaly") and maps of it exist:



Acceleration Anomaly leads to certain areas of the earth moving at different speeds, e.g. Mount Everest lies in an area with a positive anomaly. This leads to Mount Everest getting taller over time (approx. 4mm/year).

This easily answered: airlines are in on the round earth hoax. My theory:

Airlines make their pilot fly the aircraft at a precisly calculated speed. Every honest pilot will admit that there are rules on air speed. The speed of planes close to the North Pole is higher than close to the south. A simplified formula for the cruising speed of a commercial aircraft is
v_plane = v_0 * (1 - 1/r),
with v_plane, v_0 and r being the speed of the plane (relative to the ground), v_0 a constant (depending on the plane) and r being the distance between the plane and the north pole, respectively. The formula also explains why there are no flights directly above the North Pole, the plane speed would have to be zero and no plane can fly with zero speed.

The airlines speed formula works because passengers cannot reliably measure the speed above ground. This is facilitated by the fact that airline windows are very small, thick and curved, making reliable distance and speed measurements very difficult.
