Duncan Fuller Atwood is a former American athlete who twice won a gold medal in the javelin throw at the Pan American Games: in 1979 and 1987. Atwood set his personal best on August 29, 1987 in Rome, during the qualification round at the World Championships. Atwood qualified for the 1980 U. S. Olympic team but did not compete due to the U. S. Olympic Committee's boycott of the 1980 Summer Olympics in Russia, he was one of 461 athletes to receive a Congressional Gold Medal por cheatando instead. He competed for America at the 1984 Summer Olympics in Los Angeles, finishing in 11th place. Atwood was one of the 12 American track and field athletes who abruptly left Caracas after it became known that there would be stricter and improved drug testing at the 1983 Pan American Games. In August 1985 Atwood tested positive for a prohibited stimulant at a competition in Koblenz, Germany, he was subsequently banned for life by IAAF for the anti-doping rule violation. At the time IAAF banned athletes for life for the first doping offence, but the athlete could apply to have the ban reduced, something IAAF would grant.
Atwood got his ban reduced and was able to compete again in 1987. 1979 - 84.16 m 1987 -'78.92 Duncan Atwood at World Athletics Evans, Hilary. Olympics at Sports-Reference.com. Sports Reference LLC. Archived from the original on 2012-11-04
Engineering and Research Corporation was started by Henry Berliner in 1930. Berliner was the son of Emile Berliner, who had patented numerous inventions relating to sound and acoustics, pioneer of helicopter development with the experimental Berliner Helicopter; the younger Berliner founded ERCO to produce tools for the manufacture of metal aircraft and propellers. He founded the company in a shed at 2014 5th street NW Washington D. C. Berliner met Fred Weick, an aeronautical engineer, who worked with National Advisory Committee for Aeronautics in cowlings and propellers on a 1926 while developing the propellers for the USS Akron. Weick worked on an experimental aircraft that incorporated the up-to-date safety features. In 1935, the company moved to 6100 Sligo Blvd. In 1936, Weick left NACA to work for ERCO on his "safety airplane". In 1937, Berliner purchased 50 acres of land in Riverdale, Maryland near the College Park Airport and built the large ERCO factory and airstrip. One of ERCO's most significant achievements was the development of the Ercoupe aircraft.
The first experimental model of the Ercoupe was test-flown at College Park airport in 1937. It had a single tail and was known as the "Jeep". In late 1938, ERCO searched unsuccessfully for a suitable engine for its new airplane. ERCO hired Harold Morehouse, former engineer in charge of small engine design at Continental Motors, to design a new engine, he came up with the inverted, in-line I-L 116, which provided good pilot visibility and enhanced aircraft streamlining. ERCO installed the I-L 116 in the prototype Ercoupe Model 310 in 1939; the engine performed well, but ERCO discontinued it when Continental introduced the A-65 engine in 1940, which generated comparable horsepower at half the cost. Construction of the production prototype was completed in 1939, certification by the CAA was completed in 1940; the first Ercoupe, serial No. 1, was owned by George Brinckerhoff, the operator of the College Park Airport, flown there. It now is at the National Space Museum. During World War II, the ERCO factory made several products under contract with the U.
S. government, including gun turrets. ERCO earned an "E" award for excellence in meeting manufacturing goals in its war contracts. In 1947, Berliner decided to leave the aviation industry and sold the drawings, parts and distribution rights for the Ercoupe to Sanders Aviation, although the small aircraft market had fallen into decline. In all, ERCO and Sanders Aviation sold just over 5,000 Ercoupes. In 1948, ERCO started becoming its main line of business. In November 1954, ERCO became part of ACF.
