As long as globers can play the magic ''superiour mirage'' card they will never accept the errors in the current model.
How freaking far away do you have to go to take a picture that defies the current curvature model ?
Chicago skyline and the whole city without dissapearing parts from 50 miles away ?
Nope....superiour mirage..
Lighthouses seen from 80 miles ?
Nope....uh earth's gravitational pull is bending the light towards the observer as we ALL know for a fact.
You see ? They have to many mystery cards full of pseudo science that can reason away everything in favour of the globe.
But they cannot reason away the ultimate physical curvature test i'm working on.....long live the robes with over 2500 Tonne breaking strenght !
First thing that you skipped is: they saw Chicago in mid April 2015 upside down.
Why you have to wait convenient temperatures to see it? (Upside down, or not.)
Then:
on Flat Earth model Sun height above ground is impossible to measure. Curved light?
on Flat Earth model every azimuth of sunrise and sunset is wrong. Curved light?
on Flat Earth model they claim Sun doesn't set or rise, it is "perspective".
("perspective" that requires sun rays to bend upwards. Curved light?)
("perspective" that works only vertically, slowly from bottom, and horizontally doesn't work at all.)
on Flat Earht model you can not explain shadows of horizon on mountain sides and tall buildings during sunrise and sunset.
At least not without curved light.
And for all cases above, and many more, you need light to be much more curved than for mirages.
Much more curved.
