Has anyone completely circumnavigated the globe?
Yes, many people have circumnavigated the globe. The first to accomplish this feat were the survivors of the voyage of Ferdinand Magellan, who returned to Spain in 1522 after a three-year voyage around the globe that claimed most of the members of the expedition, including Magellan himself, who was killed by Filipino natives. The next voyage to accomplish the feat was that of Englishman Sir Francis Drake, who sailed around the world in his vessel The Golden Hind from 1577-1580. Since then, hundreds of people have accomplished the feat, all by sea until pilots of the United States Army Air Service did it by air in 1924. Many people have now sailed around the globe alone, and some have done so without the aid of navigation devices.
