Logan "Jack" Vilas made aviation history when he piloted his Cessna 1-85 seaplane from Saint Joseph, Michigan to Chicago's Navy Pier.
That was on July 1, 1913.
And on Monday, his granddaughter, Faith Vilas, successfully made the journey too.
"My grandfather was a pilot, my father was a pilot, my aunt was pilot, I'm a pilot. I never assumed that I couldn't fly. So I always knew that he had done a lot of aviation firsts. I thought, 'it was the 100 year anniversary,' I should try to do this," said Vilas.
Vilas has been planning the commemorative flight for two years.
