At the time of this posting I'm offering three free downloads on my website, TheFreedomSeatSeminars.com.
They are all PDFs.
One is the Storybook Version of the 1969 Powder Puff Derby, featuring Steve Canyon's sister and pilot Bitsy Beekman. Milton Caniff wrote it especially for the PPD, or All Woman Transcontinental Air Race of 1969.
One is an illustrated guide to all 100 of the Smithsonian Institutions Milestones of Flight series. Includes an image of the cachet/first day cover, and text on each cover.
The third is a PDF of Linda Finch's first newsletter for her 1997 World Flight, in which she recreated and completed Amelia Earhart's final flight in a restored Lockheed Electra.
So please check them out.
