I arrived there by chance, I didn't know it existed, at the entrance the first surprise: IT'S FREE. I was thinking of a small museum, but it's huge, divided by epochs, from the pioneers of flight to the present day, with an infinite number of fantastic aircraft. Everything is well explained on display boards all over the world, and many screens continuously show movies and vintage photos. In short, a marvel !!!!
