...he wrote for use on his own tombstone, suffices: "Author of the Declaration of American Independence, of the Statute of Virginia for religious freedom, and Father of the University of Virginia. Thomas Jefferson was born in Shadwell, Virginia in 1743. against slavery Four years later, he defeated Adams and became president, the first peaceful transfer of authority from one party to another in the history of the young nation. Perhaps the most notable achievements of his first term were the purchase of the Louisiana Territory in 1803 and his support of the Lewis and Clark expedition. His second term, a time when he encountered more difficulties on both the domestic and foreign fronts, is most remembered for his efforts to maintain neutrality in the midst of the conflict between Britain and France; his efforts did not avert war with Britain in 1812. Jefferson died on July 4, 1826, just hours before his close friend John Adams, on the fiftieth anniversary of the signing of the Declaration of Independence. He was eighty-three years old, the holder of large debts, but according to all evidence a very optimistic man. Spirit of St. Louis" was named in honor of Lindbergh's supporters in St. Louis, Missouri, who paid for the aircraft. "NYP" is an acronym for "New York-Paris," the object of the flight. Given here is a brief history of the design and construction of the - Spirit of St. Louis, the airplane that Charles Lindbergh flew solo across the Atlantic. A budget of $15,000 A single-engine plane The Spirit of St. Louis" was designed with one thought in mind: to get to Paris. Extra fuels tanks were added and the wing span increased to accommodate the additional weight. The plane would have a maximum range of 4,000 miles, more than enough to reach Paris. One of the more innovative design decisions involved placing the main fuel tank in front of, rather than behind, the pilot's seat. Lindbergh didn't want to be caught between the tank and the engine if the plane was forced to land. This configuration also meant that Lindbergh would not be able to see directly ahead as he flew. It didn't seem to trouble him much. "There's not much need to see ahead in normal flight," Lindbergh told Donald Hall. "I won't be following any airways. When I'm near a flying field, I can watch the sky ahead by making shallow banks. All I need is a window on each side to see through..." If needed, Lindbergh would use a periscope attached to the plane's left side to see what was in front of him. In his efforts to pare down the plane's weight, Lindbergh considered every detail. Any item considered too heavy or unnecessary was left behind. These included a radio, parachute, gas gauges, and navigation lights. Lindbergh designed for himself special lightweight boots for the flight, and went so far as to cut his maps down to include only those reference points he would need. Every ounce mattered. Instead of a heavy leather pilot's seat, Lindbergh would be perched in a far lighter wicker chair. Upon its completion on April 28, 1927, the "Spirit of St. Louis" weighed in at 2,150 lbs. when empty. ...
