I own at least one copy of each of Bill's books. Bill brought a very
useful
and valuable point of view and methodology to instructing. Many students
"need" numbers, their minds require the numerics and physics behind the
maneuver before they understand and accept the maneuver. Bill provided
this. I for one am and forever will be indebted to him for this alone.

I agree.
Bill's books made it possible for instructors to couple technical
information with creative teaching to present that information on levels all
students could understand.
His input to aviation will long be remembered by those of us who benefited
from his contribution.
