Well, assuming nobody continued Leonardo da Vinci's works, nope. From what I know, Leonardo didn't test the machine himself, but built it. On the other hand, from Evliya Çelebi's Seyahatname (a big set of books that contain his memoirs from his travels across all over the Empire), he met this Ahmet guy in Constantinople and seen him/heard him fly over the Bosphorus from Galata Tower (The flight is possibly somewhere over a kilometer). Which is quite an accomplishment for his time I guess.
