Radar facilities are based on land, and each one has a range of about 200 miles (320 kilometers). So passenger jets on transoceanic flights do go off the radar map for a period of time — but that doesn't mean nobody's keeping tabs on them. The flight crews use combinations of high-frequency (HF) radio, satellite-based voice communication and text-data networks to report to ATC [air traffic control] the exact time, position and flight level when the crossing begins. They then update ATC with voice or text progress reports at defined geographic locations and time intervals. Airlines file flight plans, and airplanes are expected to arrive at certain points by certain times. When an airplane crew fails to check in at its next checkpoint, that is when an alarm is raised. This case is an extremely rare event, especially with the highly technologically advanced aircraft in the air today.

Entire source is demonstrably INCORRECT AND FALSE based on MH370 results.
If this source was accurate, then MH370 never happens.
MH370 happens because the requirements aren't wide spread, and even now only about 1,000 planes have the tech installed to turn on tracking in the event of an emergency. Because upgrading old planes is relatively expensive when doing a lot of them. Not to mention we have a search area for the MH370 precisely BECAUSE of the checkpoint system. Them not finding anything yet is not evidence the source is inaccurate.
The source is inaccurate and incorrect and it also lays waste to the legitimacy of flightaware and other so-called flight tracking systems, especially south of the Equator.
The MH370 and the written ship logs of Cook, Weddell, Ross, et.al., continue to support the theory that distances across the waters south of the Equator are NOT in line with a globe Earth.
The source is inaccurate and incorrect? You were provided with four other sources that supported this source. Are they also inaccurate and incorrect? How? Other than your personal opinion, can you specify sources that is in support of your claim?
Also, you say that it lays waste to different flight trackers. Well thats a no! If anything it supports them, by confirming a certain flights track.
Are you referring to James Weddells voyage in 1822-24? If so; you then draw a straight historical line between him and MH370. Actually ignoring...well...every piece of updated information in between. Obviously his findings were coherent with FE, but he was certainly not correct. May I remind you that his journey was more than 200 years ago. I dont understand also how MH370 would prove Weddell correct. Can you elaborate?
