George R. Wood, 64, a retired Air Force colonel who won three Distinguished Flying Crosses as a bomber pilot in World War II and who joined his wife in a women's apparel business in Northern Virginia after he left the service died Monday in a hospital in Margate, Fla. He had a heart ailment.

Col. Wood, who lived in McLean, was in Margate on an extended business trip when he was stricken.

He was born in Santa Cruz, Calif., and joined the old Army Air Corps in 1941. During World War II, he was a bomber pilot in the Pacific. In addition to three DECs, he was awarded five Air Medals. His postwar assignments included duty at a number of posts in the United States and a tour in Britain. While stationed in Omaha, Neb., he earned a bachelor's degree in education from the University of Omaha. From 1959 until his retirement in 1967, he was stationed here at Air Force Headquarters and the Defense Supply Agency.

Col. Wood then went to work with his wife, Eleanor, in expanding a retail women's apparel business she had already started. It is called Eleanor's Town and Country Inc. and has outlets in McLean, Manassas, Springfield, Oakton and elsewhere.

In addition to his wife, of McLean, Col. Wood is survived by two sons, Michael, of Santa Barbara, Calif., and Gary, of McLean; two daughters, Michelle Huber of Manassas, and Sandra Hindman of Bellevue, Neb., and five grandchildren.

The family suggests that expressions of sympathy be in the form of contributions to the Northern Virginia Heart Association.
