Thanksgiving eve in the shop….


In anticipation of a day off, I spend the evening wrapping up some details on engines at the SPA/Panther factory. A pleasant time in the shop listening to Led Zeppelin’s masterpiece, “Physical Graffiti” for the zillionth time in my life.

I was 13 years old and living in Hawaii when Physical Graffiti was released. I was in 7th grade  at tough private institution named Punaho. It was an excellent education; one of my schoolmates became President of the United States 32 years later.


I distinctly recall hearing the song “Night Flight” and not really knowing who Led Zeppelin was, but intrinsically understanding this was something different than the ubiquitously popular KC and the Sunshine Band.  40 years later,  I have spent countless nights working on machines, in too many different shops and hangars to remember.  The songs on Physical Graffiti  are an unchanged constant, threading these places and times in my life together.




About William Wynne
I have been continuously building, testing and flying Corvair engines since 1989. Information, parts and components that we developed and tested are now flying on several hundred Corvair powered aircraft. I earned a Bachelor of Science in Professional Aeronautics and an A&P license from Embry-Riddle Aeronautical University, and have a proven 20 year track record of effectively teaching homebuilders how to create and fly their own Corvair powered planes. Much of this is chronicled at and in more than 50 magazine articles.
