Erm, did you even read the blog, bruh? So I'm guessing you have built-in fish-eye lenses in your eyes? I've flown all over the stationary plane, from Europe to South America and back twice, from Europe to Asia and back multiple times. Never did I witness the curve. Not one time did the pilot nose down to adjust to the curve. Ever wonder why flights from east to west take almost as long as flights from west to east, although your fairy-tale globe is spinning due east?
