Already in the 10th century, the Vikings discovered America. Bjarni Herjolfsson wanted to visit his family on Greenland, but was blown off course and instead reached the coast of America.
Because he wanted to see his family as quickly as possible, he didn't go ashore. Once in Greenland, he told his story. His listeners accused him of a lack of curiosity for not having a look on land. Later other expeditions followed.
