Retired Air Force Maj. William Wylie Moore, 61, who served as a bomber-navigator in the Pacific during World War II, died of a brain tumor Saturday at Bethesda Naval Hospital.

He was serving with the 92d Bombardment Wing in Spokane, Wash., when he retired from military service in 1956.

Maj. Moore then came to Washington, where he joined the aeronautical chart and information center at Air Force headquarters as a civilian.

He later worked with the Army medical research and development command and then was a program analyst at Air Force headquarters until his second retirement in 1975.

Born in Chester, S.C., Maj. Moore was a graduate of Erskine College and was a coach and high school superintendent in South Carolina before joining the Army Air Forces in 1941.

His heroism in the Pacific, for which he received the Distinguished Flying Cross, was noted by the Legion of Valor in accepting him later for membership.

The organization wrote that he successfully navigated a plane through enemy fire, thus "materially aiding in the success of the first torpedo attack ever carried out by the Army Air Force." It was in action near Midway Island in June, 1942.

After the war, Maj. Moore served at numerous bases in this country, in Okinawa and in England.

He is survived by his wife, Loretta, of the home in Camp Springs; a brother, C. Johnson, of Wilson, N.C., and a sister, Amy Hyatt, of Asheville, N.C.
