Are you saying that it's possible to fly around the world in a flat earth, east to west or west to east?
How about you provide me a model of your flat earth. Make sure it's the model you really buy into as I can then prove through flight patterns that your model doesn't line up with reality.
All commercial flights are over a flat, motionless earth in all directions. The land and seas below all commercial flights rise up to eye level and no curvature is even seen and no movement of the earth below is ever apparent.
On a curved earth the ground and seas would drop further below our eye level the higher we ascend.
No flights fly "around" anything. They fly in straight paths once a cruising altitude is rached for long distance flights from one city to another.
Funny how we have to be constantly told by globers that what we are experiencing is not real.
