A Question for the Flat-Earthers

So, when Ferdinand Magellan and Sir Francis Drake first circumnavigated THE GLOBE, they had accomplished WHAT in your estimation, traversed the outer rim of some big, flat circle? And how do you explain it that you can successfully fly from New York to Tokyo by heading in whichever direction that you desire?......Of course the earth is round (no, not completely but pretty damn near), you fucking idiots!! Enough already with this shit.
