[snip]... Why is there no tracking data for ocean crossing flights in the southern hemisphere?
If the Earth were flat, shore based tracking systems would be able to track these flights using line of sight technologies. Given that they can't, due to the curvature of the Earth, you've basically just proven that the Earth is not flat.
Welcome back to reality.
You again. Every time you got debunked, you always came back again with Y.A.BC.
We already established through the countless of pages here that there is
NO curvature of the earth.
There is no explanation why any flight should not be tracked fully anywhere, other than intentional obfuscation of flight path data. Because to do so would expose the lie of the spinning ball earth model. End of debate.
Don't even reply anymore here unless you can provide:
1. A real authentic footage of a curved oceans.
2. A live feed of southerners living upside or side side down.
3. A real authentic footage of a curvizon.Welcome to the flat earth truth.

Don't be to quick, research flat earth.
