Thanks for the note Keith. Yes, we can certainly leave a note for Jeff. However I think a better approach would be for you to consider initiating a standalone page on the Orbitsphere that we can all help on. Part of that page could include a discussion of great circle, including what you learned when you looked it up. My hope is that the material in Jeff's presentation is gradually replicated in Wiki format. That way anyone can improve it part by part.
