Charles in 1927. This feat, when Lindbergh was only twenty-five years old, assured him a lifetime of fame and public attention. Charles Augustus Lindbergh was more interested in flying airplanes than he was in studying. He dropped out of the University of Wisconsin after two years to earn a lMng performing daredevil airplane stunts at country fairs. Two years later, he joined the United States Army so that he could go to the Army Air Service flight-training school. After completing his training, he was hired to fly mail between St. Louis and Chicago. Then came the historic flight across the Atlantic. In 1919, a New York City hotel owner offered a prize of $25,000 to the first pilot to fly nonstop from New York to Paris. Nine St. Louis business leaders helped pay for the plane Lindbergh designed especially for the flight. Lindbergh tested the plane by flying it from San Diego to New York, with an overnight stop in St. Louis. The flight took only 20 hours and 21 minutes, a transcontinental record. Nine days later, on May 20,1927, Lindbergh took off from Long Island, New York, at 7:52 He had flown more than 3,600 miles in less than thirty four hours. His flight made news around the world. He was given awards and parades everywhere he went. He was presented with the U. S. Congressional Medal of Honor and the first Distinguished Flying Cross. For a long time, Lindbergh toured the world as a U. S. goodwill ambassador. He met his future wife, Anne Morrow, in Mexico, where her father was the United States ambassador. During the 1930s, Charles and Anne Lindbergh worked for various airline companies, charting new commercial air routes. In 1931, for a major airline, they charted a new route from the east coast of the United States to the Orient. The shortest, most efficient route was a great curve across Canada, over Alaska, and down to China and Japan. Most pilots familiar with the Arctic did not believe that such a route was possible. The Lindberghs took on the task of proving that it was. They arranged for fuel and supplies to be set out along the route. On July 29, they took off from Long Island in a specially equipped small seaplane. They filew by day and each night landed on a lake or a river and camped. Near Nome, Alaska, they had their first serious emergency. Out of daylight and nearly out of fuel, they were forced down in a small ocean inlet. In the next morning's light, they discovered they had landed on barely three feet of water. On September 19, after two more emergency landings and numerous close calls, they landed in China with the maps for a safe airline passenger route. Even while actively engaged as a pioneering flier, Lindbergh was also working as an engineer. In 1935, he and Dr. Alexis Carrel were given a patent for an artificial heart. During World War I in the 1940s, Lindbergh served as a cMlian technical advisor in aviation. Although he was a cMlian, he filew over fifty combat missions in the Pacific. In the 1950s, Lindbergh helped design the famous 747 jet airliner. In the late 1960s, he spoke widely on conservation issues. He died August 1974, having lived through aviation history from the time of the first powered flight to the first steps on the moon and having influenced a big part of that history himself. When did Charles meet Anne Morrow?

The main advantage of inertial guidance systems in modern aircraft, spacecraft, and submarines is that they are and are able to function without data.

The science of astronomy is widely viewed today as at least as much as theoretical, in that sooner or later what astronomers detect finds its way into theory, or the theory is modified to it.

The amount of bone in the elderly ske|eton—a key determinant in its susceptibility to fractures-is believed to be a function of two major factors. The first is the peak amount of bone mass attained, determined to a large extent by genetic inheritance. The marked effect of gender is obvious: Elderly men experience only one-half as many hip fractures per capita as elderly women. But also, African- American women have a lower incidence of osteoporotic fractures than Caucasian women. Other important variables include diet, exposure to sunlight, and physical actMty. The second major factor is the rate of bone loss after peak bone mass has been attained. While many of the variables that affect peak bone mass also affect rates of bone loss, additional factors influencing bone loss include physiological stresses such as pregnancy and lactation. It is hormonal status, however, refilected primarily by estrogen and progesterone levels, that may exert the greatest effect on rates of decline in skeletal mass. It can be inferred from the passage that the peak amount of bone mass in women
