In November 1950 twin sons, Michael Wayne and Mark Clay were born. Billy had played golf since he was 10 so it was natural that he would introduce his sons to the game. He enjoyed playing golf with them many times. As a member of Indian Springs Country Club in Broken Arrow for 24 years, he loved to play almost every day. He liked to enter the club tournaments and also the "Retired Old Boys" tournaments. Later when grandchildren visited, they ended up hitting golf balls or driving the golf cart.

His first love of occupation was the Aviation field. In this area, he worked on the B-36 bomber built by Convair in Fort Worth, Texas, the Atlas Missile sites around Topeka, Kansas, the Titan II Missile sites around Tucson, Arizona and he served as a Supervisor in the Electronics Engineering Department of Tulsa's North American Aviation Division on the NASA Apollo Moonshot Program.

He also worked for several major engineering companies such as Fluor Company, Refinery Engineering Company, and Lummus Crest, Inc. During his engineering career he was registered as a Professional Engineer in the state of Oklahoma and Texas.

He was a member of the Destroyer Escort Sailors Association, the Destroyer Escort Historic Museum, and a lifetime member of DAV, IEEE and the American Legion. He served as the Tulsa Section Chairman of the Institute of Electrical and Electronic Engineers in 1979-1980. He retired in 1985 from Lummus Crest Inc. as a Senior Principal Engineer serving as a Project Manager or as a Project Director.
