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.

A fine gentleman, a great pilot, and a real contributor to our sport.
The story of his O&R world record is very much worth reading.
I am lucky to have known him.
