A sublimely gifted writer the late CL to be sure. His lyrical evocations of solo flight (and many other aspects besides),are matched by Phillip Wills "On Being a Bird", by PG (Sir Gordon) Taylor, "The Sky Beyond",
We have similar tastes in literature!
I have two of Lewis' books:
Sagittarius Rising, and
Gemini to Joburg. I like them both very much.
I have three books by Phillip Wills:
On Being a Bird,
Free as a Bird, and
Where No Birds Fly. They are all good, although (inevitably) perhaps somewhat dated now.
I have a copy of
The Sky Beyond, but I read it so long ago that I can't now recall much about it.
Apparently George Moffat has recently published a sequel to his classic,
Winning on the Wind. Does anyone have any information about that?
