If you unironically have fallen for the flat earth CIA psyop, there is one easy experiment you can do to prove yourselves wrong.
Step 1: buy GPS enabled go-pro
Step 2: buy high altitude capable balloon
Combine the two, watch the balloon go up, track where it lands, watch the footage for yourself and free yourself from Mockingbird bondage.
For a little extra, you can configure a live feed system and watch everything in real time all under your control! Yes, it really is that simple!!!
So... You agree with black science man when it's convenient, but have not conducted any extensive research yourself?
