Following in the footsteps of Bartholomeu Dias, another explorer left Portugal in 1497 A.D., hoping to sail around Africa and reach India. This explorer was Vasco Da Gama.
Da Gama set out with four ships from his homeland in Portugal. Ten months later he and his men arrived in Calicut, India. Here they established ties with the leaders of this city, and attempted to set up a trading partnership.
While their efforts to set up a partnership with Indian traders was not successful, they did prove once and for all that moving goods over the sea was possible. Vasco Da Gama and his men returned to Portugal as heroes.
Truth is its own reward.
In 1783 Marquis d''Arlandes And Pilatre de Rozier became the first humans to fly. They used a hot air balloon, which kept them in the air for about 20 minutes.
