Yes, Eowyn, I *did* know that, but thank you for the reminder - I had not been thinking of it until you alerted me. I remember the anniversary date very well - in 2003, I was fortunate enough to be able to go to Kitty Hawk, North Carolina for the centennial celebration. The accomplishments of the Wright brothers are beyond my ability to fathom. Some of the tools and techniques they had to invent/create/develop in order to accomplish their amazing feat are still in use today in analysis of aircraft design.
