input: Van Buren claimed his second rushing title in 1947, which was the first in a string of three straight. His 1,008 rushing yards broke the single-season record of 1,004 set by Beattie Feathers with the Chicago Bears in 1934. He was no longer returning punts for the team, as the role was taken over by halfback Bosh Pritchard, though he still returned kickoffs. His 95-yard kickoff return touchdown against the Washington Redskins in the first game of the season was again the longest kickoff return by any player that season, as well as the last kick return touchdown of his career.  The Eagles and Pittsburgh Steelers both finished the 1947 regular season atop the Eastern Conference with an 8-4 record, so the two teams met for a tiebreaker game to determine the conference champion. During the week before the game, the Steelers ran workouts concentrating on a means of stopping Van Buren's running. In the game, the Steelers' defensive line held Van Buren to 45 rushing yards and no rushing touchdowns, but he scored the game's first touchdown on a 15-yard reception from quarterback Tommy Thompson. The Eagles won with a 21-0 shutout, setting them up to face the Chicago Cardinals in the NFL Championship Game, the first championship game appearance in franchise history. Against the Cardinals' "Million Dollar Backfield", Van Buren was held in check, as the Eagles were defeated 28-21 in a back-and-forth contest.  The 1948 season was the second straight that Van Buren led the league in carries, rushing yards, rushing touchdowns, and yards from scrimmage. In Week 3, in the first quarter against the New York Giants Van Buren scored his 39th career rushing touchdown, surpassing Ernie Nevers as the all-time leader. That game--a 45-0 shutout win--was the first in an eight-game winning streak for the Eagles in which they scored 275 points total and allowed 49. The team finished the regular season with the best record in the Eastern Division and were to meet the Chicago Cardinals again for the league championship.

Question: James Harold Doolittle (December 14, 1896 - September 27, 1993) was an American aviation pioneer. A Reserve officer in the United States Army Air Corps, Doolittle was recalled to active duty during World War II. He was awarded the Medal of Honor for personal valor and leadership as commander of the Doolittle Raid, a bold long-range retaliatory air raid on the Japanese main islands, on 18 April 1942, four months after the attack on Pearl Harbor. The attack was a major morale booster for the United States, and Doolittle was celebrated as a hero.

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.

Using a quote from the above article, answer the following question: Did he contribute anything to the program during this time?
