Two Famous Explorers

    Throughout history, we have benefited from the courageous explorers whose daring adventures opened new frontiers to us. Whether they set out to sail the seas, cross unexplored lands, or take to the skies in flight, they changed our perception of the world.

    Vasco da Gama is one such explorer. He was the first European to sail from Europe (Portugal) around Africa to India and back. In 1497, with four ships, he made the trip to India in 23 days. The return trip, however, took almost four and a half months because of the monsoon winds. If he had listened to the advice of the local people and waited, he wouldn't have lost more than half of his crew. He returned with only two of the four ships. If he had waited a while before returning to Portugal, maybe all four ships would have returned with him. Da Gama was a true adventurer, and his discovery brought the spice trade to Portugal.

    Charles Lindbergh was an explorer of the skies who made the first solo flight across the Atlantic Ocean. As a young man, Lindbergh's interest was in aviation. He dropped out of college to travel around the country performing airplane stunts for audiences at county fairs. In 1924, he joined the army and received pilot training. Later, he was hired to fly mail between St. Louis and Chicago. If Lindbergh had stayed in school and studied engineering, he probably would have never become a pilot. In 1927, Lindbergh set a goal to be the first person to fly non-stop from New York to Paris and win a $25,000 prize for doing so. On May 20, 1927, Lindbergh took off in his plane, the Spirit of St. Louis, and flew almost 4,000 miles across the Atlantic in 33.5 hours. After this historic feat, Lindbergh continued to promote aviation and even wrote a book about his transatlantic flight. If Lindbergh hadn't traveled around the country on a post-flight tour, people wouldn't have considered aviation as a means of travel.
