William C Holbrook passed away peacefully last night at the age of 98. He was a long time family friend, professional pilot and holder of many soaring records. Also a member of the SSA hall of fame.
He and my father, Ed Byars, had a long friendship and contributed much to the art of soaring with their Soaring Symposiums.

Condolences and best wishes to Mr. Holbrook's family and friends. I just came across my signed copy of "Soaring Cross Country" and marveled at how the sport has progressed. Ed and Bill were leaders in making that happen. Respects to all.
