Flights are impossible to project onto the Globe because of the differences in latitude and longitude in the southern hemisphere when compared with the true world map which is the UN logo.
I don't think that you understand how projection works.
Flights can be tracked using GPS

They chose not to as it would prove the Flat earth and wouldn't corelate with their imaginary Globe Hence why flight tracker shows flights magically dissappearing just after take off then magically reappearing near their destination.
Your Strange Heliocentric Religion is False.
Flights do not disappear just after take off. You need to understand how sites like Flightaware work. Aircraft know their accurate position using onboard GPS receivers. They then transmit their position and other information using ADS-B. Sites like Flightaware use a network of scattered, often amateur, land based receivers to pick up the transmissions and feed it to the website. Reception is limited to about 50 miles hence there is limited coverage over oceans etc.
Understand?
Sounds very convenient 
Flight tracker seems to work fine in the northern hemisphere over oceans.
Your Strange Heliocentric Religion is False.
There are some shown in the southern hemisphere. Involves having suitable receiving equipment. Also there are fewer flights across oceans in the south.
What's convenient, it's a proven system?
And the transmitted data includes the speed which proves distances and hence the shape of the earth.

https://en.m.wikipedia.org/wiki/GPS_aircraft_trackingA GPS aircraft tracking solution is made possible when an aircraft is fitted with a GPSreceiver. By communication with GPS satellites, detailed real-time data on flight variables can be passed to a server on the ground. This server stores the flight data which can then be transmitted by usingtelecommunications networks to organisations wishing to interpret it.
The different kinds of telecommunication networks used are:
ACARS - a hybrid of the VHF, satellite and HF networkThe transponder "Mode S" (ADS-B) networkSatellite networks (Globalstar, Inmarsat,IRIDIUM, Thuraya)The GSM network
Some devices are avionics components likeACARS and ADS-B. In these cases the receiving and transmitting antenna are usually located outside of the airframe.
When devices are not installed as avionicscomponents they have to be completely independent from the aircraft. They are typically placed inside of the airframe in a location where the GPS and communication satellites are directly visible to the device, for example through the cockpit window. The output signal must also be able to penetrate the aircraft - most civil aviation authoritiesrequire compliance with DO-160 for audio frequency conducted susceptibility and induced signal susceptibility.
Authorities classify non-installed components as "transmitting portable electronic devices" (T-PEDS) and as such require them to be switched off during the critical phases of flight.[1]
No that is not acceptable.
Flight tracker displays flights over the ocean in the northern hemisphere but not the southern hemisphere.
This is because if they displayed the flights in southern hemisphere it would de bunk there imaginary Globe.
There is no point in me posting a link to flight tracker people that are interested will look for themselves all it takes is a quick Google.
