@ChristiferBrown Do you notice the distance between the other plane and where the contrail starts to appear? This, and certainly a long list of other factors could have caused you not seeing your own plane's contrail. What makes you so sure of your assumptions?
@Groopert1 You could find yourself a flat earther friend some miles away. Then you can exchange pictures of what you see at the same time. Maybe this will save the rest of X from posts like this.
@Manasseh1203@judd_dredge@plantblazer@thug_liafe Ask flat earthers like @plantblazer if the map you are showing is a flat earth map. He will tell you it is a globe projection. This kind of completely nulls any argument you were trying to make with comparing that map to the UN logo.
@GroveStudios7@rjheathfield@FlerfWatch That globe was created ~1492 and has long been superseded by better data. No need to fix it.
Gleason map came 400 years later and is from 1892. It is is still treated as the best flat earth has to offer by many.
@CreatorJonwPuck@AdonaiOnGaia The picture you posted shows the moon getting closer to the horizon with constant size. Shouldn't it get smaller as it "moves away" (a common claim heard from flat earthers)?
@sashuwa77246@did8hurtu Depends on their intended usage, quality of surveying, time of surveying and many other factors. Modern digital maps can be made to be very accurate.
