The Wright one

Returned to Dayton with Marina so she could see the Wright Flyer III and experience the Brothers progress from printers to bicycle repairs to bicycle manufacturers to aviation pioneers.
She's hooked and ready to learn more about historical feats like they accomplished. Looks like Kitty Hawk is on the way home.

They determined the accepted lift calculations were wrong so they built their own wind tunnel to test wing designs!

Did their own sewing on a Singer. 

Just love panoramic function.
