Walter H. Wood, 63, a former official of the National Aeronautics and Space Administration, was killed Aug. 11 in a car accident in Jessup, Md. He lived in Fairfax.

A Maryland State Police spokesman said Mr. Wood was driving on I-95 when his car veered and hit a guard rail. He was pronounced dead at the scene.

Mr. Wood joined NASA as an electronics engineer in 1957. He was a data collection supervisor and manager of the Nimbus satellite project. He retired in 1970.

Since then, he had taught flying and aerobatics at airports in Annapolis and Warrenton. At the time of his death, he was working at Century Aviation in Leesburg, Va.

Mr. Wood was born in Amherst, Tex. He served at sea as a radioman in the Navy during World War II.

He came to Washington after the war and graduated from George Washington University. He worked at the National Bureau of Standards before joining NASA.

Mr. Wood had won numerous honors in international ballroom dancing.

His first wife, Frances Louise, dies in 1968.

Survivors include his second wife, Catherine D., of Fairfax; a daughter, Marian Underwood of Waldorf; three sons, Stuart A., of Mount Laurel, N.J., and John W. and Gary N., both of Alexandria; a sister, Violet Knox of McCamey, Tex.; two brothers, Sykes, of Austin, Tex., and Maurice, of Vista, Calif., and four grandchildren.

The family suggests that expressions of sympathy be in the form of contributions to the Washington chapter of the U.S. Amateur Ballroom Dancers Association in care of Richard Mason, Box 55, McLean, Va. 22101.
