I don't see any reason to trust those flight radar sites or that the flights exist as claimed.

So no, I don't see any verifiable evidence that these systems are actually providing accurate data.
Wow.
So what are you suggesting is happening on FR24 then? Do you, like the author of that book, subscribe to the view that NASA are somehow providing the data to FR24, and that they distort everything to make it look like aircraft are flying great when they are, in fact, flying over some version of FE?
Do have any idea how utterly preposterous that sounds? I note you edited out his NASA conspiracy bit…is that because it doesn’t align with your wiki claim that there is no FE/RE conspiracy, just a space travel one? Or do you actually agree it’s a NASA thing?
So many things…what do you suppose happens on that Ethiopian flight then? Does it take roughly 12 hours to cross over to Sao Paulo?
Do you even understand how FR24 works? It is based on the ADS-B signal from aircraft, which carries unencrypted navigation data along with other information. The critical point to hoist aboard is it is fairly short range - 100 miles or so, depending on altitude. To get a global picture FR24 relies on lots of ground stations. The really cool thing is that you can become one yourself - this website explains it pretty well:
https://www.kaspersky.com/blog/tracking-airplanes-how-flightradar24-works/8389/amp/The really important bit to note is that one of the main reasons for the system is to provide position information to ATC and other aircraft for safety purposes. If the data was wildly out, as you are suggesting, it would be extremely dangerous, as well as being very obvious to anybody flying an aircraft.
You are taking the word of a single person who draws NASA as a puppeteer controlling the flight information websites, but are rejecting a wealth of entirely consistent data from a global industry. Why?
