>>11894219Do you believe you made some kind of point? Pilots specifically do NOT involve curvature in flying around a supposed ball going over the speed of sound (nevermind to the degree of fighter pilots going incredible speeds, even their jets are designed with 'assumed continual horizontal ground' in their patents. Likewise, Fishermen absolutely do NOT factor in curvature WHATSOEVER while sailing. In fact captain dumbass, nautical sextants are a dominant tool of blowing apart curvature. Back to your uber.
