input: Doolittle became acquainted with the field of space science in its infancy. He wrote in his autobiography, "I became interested in rocket development in the 1930s when I met Robert H. Goddard, who laid the foundation [in the US].... While with Shell [Oil] I worked with him on the development of a type of [rocket] fuel...." Harry Guggenheim, whose foundation sponsored Goddard's work, and Charles Lindbergh, who encouraged Goddard's efforts, arranged for (then Major) Doolittle to discuss with Goddard a special blend of gasoline. Doolittle piloted himself to Roswell, New Mexico in October 1938 and was given a tour of Goddard's workshop and a "short course" in rocketry and space travel. He then wrote a memo, including a rather detailed description of Goddard's rocket. In closing he said, "interplanetary transportation is probably a dream of the very distant future, but with the moon only a quarter of a million miles away--who knows!" In July 1941 he wrote Goddard that he was still interested in rocket propulsion research. The Army, however, was interested only in JATO at this point. Doolittle was concerned about the state of rocketry in the US and remained in touch with Goddard. Shortly after World War II, Doolittle spoke to an American Rocket Society conference at which a large number interested in rocketry attended. The topic was Robert Goddard's work. He later stated that at that time "...we [the aeronautics field in the US] had not given much credence to the tremendous potential of rocketry. In 1956, he was appointed chairman of the National Advisory Committee for Aeronautics (NACA) because the previous chairman, Jerome C. Hunsaker, thought Doolittle to be more sympathetic to the rocket, which was increasing in importance as a scientific tool as well as a weapon. The NACA Special Committee on Space Technology was organized in January 1958 and chaired by Guy Stever to determine the requirements of a national space program and what additions were needed to NACA technology. Doolittle, Dr. Hugh Dryden and Stever selected committee members, such as Dr. Wernher von Braun from the Army Ballistic Missile Agency, Sam Hoffman of Rocketdyne, Abe Hyatt of the Office of Naval Research and Colonel Norman Appold from the USAF missile program, considering their potential contributions to US space programs and ability to educate NACA people in space science.

Answer this question "Did he accomplish anything specific during this time?"
output: Doolittle, Dr. Hugh Dryden and Stever selected committee members, such as Dr. Wernher von Braun from the Army Ballistic Missile Agency,

Question: Lindsey Caroline Vonn (nee Kildow ; born October 18, 1984) is an American World Cup alpine ski racer on the US Ski Team. She has won four World Cup overall championships--one of only two female skiers to do so, along with Annemarie Moser-Proll--with three consecutive titles in 2008, 2009, and 2010, plus another in 2012. Vonn won the gold medal in downhill at the 2010 Winter Olympics, the first ever in the event for an American woman. She has also won a record 8 World Cup season titles in the downhill discipline (2008-2013, 2015, 2016), 5 titles in super-G (2009-2012, 2015), and 3 consecutive titles in the combined (2010-2012).

In her Olympic debut at the 2002 Winter Olympics at age 17, Vonn raced in both slalom and combined in Salt Lake City, with her best result coming with sixth in combined. On March 4, 2003, she earned a silver medal in downhill in the Junior World Championship at Puy Saint-Vincent, France. Vonn credits a change in her attitude toward training to a bike ride with fellow ski racer Julia Mancuso and Mancuso's father Ciro when Vonn visited them at their home in Lake Tahoe, California. With little biking experience, she quickly found herself miles behind Julia and Ciro. Alone and embarrassed, she realized she needed drastic revision of her training regimen and her attitude toward training if she was going to be successful. On March 24, 2004, Vonn was the downhill silver medalist at the U.S. Alpine Championships at Mt. Alyeska Resort, Girdwood, Alaska. Earlier that year 2004, Vonn climbed onto the World Cup podium for the first time with a third-place finish in downhill in January 2004 at Cortina d'Ampezzo, Italy. Her maiden victory in that specialty came at Lake Louise, Alberta, in December 2004. She captured five more World Cup podiums over the next two months. In 2005, she competed in four races at her first World Championships held in Bormio, Italy, pulling in fourth-place finishes in both the downhill and the combined. She was ninth in super-G, but failed to finish the giant slalom. She cited the unexpected appearance of her father, with whom she has a strained relationship, for rattling her before the event.

Using a quote from the above article, answer the following question: What happened to Lindsey Vonn in 2002?
