DESCRIPTION: Lyon was, for a weekend, the model aircraft capital. Gathered around a enclosure of 1.200m2, 100,000 fans were able to watch helicopters, all sorts of planes, including jets, small and large, giving demonstrations in the air and on the ground! From construction to flying, the different facets of model airplanes are attracting more and more impassioned adherents, of which France has 25,000.
