if you have your copy of the aforementioned book, look on page 11 and read the first 8 words on the page.
unless you have actually read the book, or have it in your hands, you are just reading some review.
And an interesting tidbit is on page 12, footnote 1 in which courts acknowledged that the wrights had priority on any method for presenting the right and left wings at different angles. (aileron principle)
Care to read the book, or even prove you have it in your hands?
oh and the smithsonian:
