Issues in Flight Analysis

Issues in Flight Analysis refers to the issues in using flight information as a scientific tool for determining the layout or dimensions of the Earth. It is often asked whether it is possible to use flights to determine geographical information about the Flat Earth models under investigation (Ie. The Bi-Polar Model or other possible models).

There are many factors to consider other than geography, such as jet streams and trade winds. Non-stop flights are not necessarily always non-stop for various reasons. It is found that planes can and do travel at supersonic speeds (groundspeed) on a regular basis. Investigators have also found that listed flight times are purposely skewed by large amounts. The wind anomalies and conditions may exist differently over different parts of the Earth. Based on these complications, it is difficult to utilize the flights in any certain way in investigation of the Flat Earth geographic models in discussion.

Jetstreams Enable Routine Supersonic Flight (Groundspeed)
Riding a Wild Wind, Transatlantic Jets Fly Faster Than Ever (Archive)

A 200-mph jet stream has sent several passenger jets to nearly 800 mph and helped break a (subsonic) speed record.

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.

Prevailing Winds
Maps of the Trade-winds show that winds can travel in both Easterly and Westerly directions in the Northern and Southern Hemispheres:



Ocean Currents
The winds also cause the direction of the ocean gyes, which in turn show both Easterly and Westerly directions in the Northern and Southern Hemispheres.



Note: The seen clockwise and counter-clockwise prevailing wind and ocean currents runs contradictory to the Coriolis Effect. See Coriolis Effect (Weather)

Non-Stop Flights
Reported issues with Non-Stop flights may suggest that the existing flights depend on a balance of physical phenomena.
